Transcript of 10-12 Elements science project

Why are all these elements in the same group? These elements (generally) are very good at conducting heat and electrically. They are not the only elements in this certain group. (They're 32 other elements in this group) These elements are call Transition metals because of how well they can transfer heat from one thing to another 10 Nickel, Palladium, Platinum and
Darmstadtium 11 Copper, Silver, Gold and
Roentgenium 12 Zinc, Cadmium, Mercury and
Copernicium Elements 10 - 12 in The Periodic Table Physical properties: Silvery White color
Shiny surface
Ductile and Malleable
1,555 C degrees melting point
Density is 8.9
One of the only naturally metals that is very magnetic
Less magnetic then iron and cobalt Nickel Physical Properties:
Silvery white.
Ductile and Malleable.
Able to absorb hydrogen gas like a sponge.
Can absorb up to 900 times its own weight. Palladium Physical Properties:

1,773 C melting point
Density 21.45 grams
One of the densest elment Platinum Physical Properties:
1 Isotope
A lot of the metal darmstadtium is unknown because it is so new Darmstadtium Platinum Some examples of these metals are: Nickel is used to make a coin in U.S.A. that is also called the Nickel
In factories it's melted together with other metals to make a alloy
You can make Jewelry with the metal Nickel
You can also find Nickels in some meteorites
Mainly used to make stainless steel objects Fun facts! Chemical Properties:
Most reactive of the metals.
Combines poorly with oxygen.
If in powder form it will catch on fire.
Doesn't react with acids.
Only when the temperature is high enough will it mix with the acids.
It will also combine with Fluorine and Chlorine at high temperatures.
Isotopes are Pd 102-110 Used for: A catalyst when making jewelry
The catalyst is also used in various other items.
Sometimes used for breaking down a petroleum to make high quality gasoline or other items. It's also used in making alloys. Chemical properties:
It is very unreactive
Does not combine with oxygen or water at room temperature
Higher the temperature the more reactive it becomes.
In it's gas form it reacts with steam to make hydrogen gas
Ni51 - Ni55 This metal was called "Devil" in the past because they used it as a "Fool's gold" so to speak, but with copper instead of gold.
Their is a allergy associated with silver. When some people touch the metal there body starts to develop a rash at the afflicted areas. Chemical Properties:
Relatively inactive.
Not attacked by most acids
Will dissolve in Aqua Regia
Dissolves in very hot alkali metals
It will absorb a large amount of hydrogen gas at high temperatures
Isotopes, Pt188- Pt198 Some things it used for would be:
Making jewelry (Mainly bracelets and certain types of rings and necklaces)
Catalysts are also made using platinum
Platinum catalysts are mainly used in cars.
Such as spark plugs.
It used in small amounts of making some alloys Chemical Properties:
It's so unstable that studying it is nearly impossible.
By the time it's made it is decomposed by other natural elements. Other used of this metal are non existance as of right now. Again they just discovered the metal and don't understand it very well yet Palladium Physical Properties:
Reddish brown
Fairly soft and ductile
Electric energy passes through it very quickly
Melting point is 1,083
Boiling point is 2,593
Density is 8.96 Copper Physical Properties:
Shiny surface
Most Ductile and Malleable metal
Conducts heat and electricity better than any other element
Also reflexs light Extremely well Silver Chemical Properties:
Moderately reactive
Dissolves in most acids and alkali metals
When copper comes in contact with moist air it combines with water and carbon dioxide, making hydrated copper carbonate
Cu61 - Cu67 are the isotopes Uses of copper in everyday life would be:
Copper is mainly used to make wires that transfer electric energy.
Some of it is turned into alloys of copper, such as brass.
The same alloy is used in making roofs some some buildings <-- Nickel Malleable: Ability to be hammered or pressed permanently out of shape without breaking or cracking

Ductile: Capable of being hammered out thin

Aqua Regia: fuming liquid composed of one part nitric acid and three to four parts hydrochloric acid

Alloy: A substance composed of two or more metals, or composed of one metal (or more) combined with a non metal through the process of fusion

Catalyst: something that causes activity between two or more persons or forces without itself being affected.

Electroplating: process by which a thin layer of one metal is deposited on the surface of a second metal Vocabulary Chemical Properties:
Melting point 961.5 C
Boiling point is about 2000-2200C
Density is 10.49 grams
Very inactive
Reacts slowly with sulfur compounds in the air, This turns the silver into silver sulfide
silver does not act readily with water, acids or many other compounds
only burns in powder form
107 and 109 are the stable isotopes People use silver for:
10% is used to make coins jewelry and artwork
2nd most important use is making wires in electric items
silver (and a bunch of other things) helps create films Physical Properties:
Gold and shiny
Melting point is 1064.43C
Boiling point is 2807C
Density is 19.32 grams
Malleable and soft
Sometimes back ruby or purple
When divided gold is a good conductor of electricity and heat Gold Chemical Properties:
Isotopes 194Au-Au199
Good reflector of infrared radiation Some uses for gold are:
Making coins, and jewelry
Sometimes used for dental work
Also used for pimping out (Aka Rims and reflectors)
Sometimes turned into a alloy to make it harder Physical Properties:
No color
Solid Roentgenium Chemical Properties:
Radioactive Because of how new this metal is, there is a lot
unknown about this metal. Therefore it's impossible to put any information about this metal Physical Properties:
Bluish white
Shiny metal surface
Not ductile or malleable
At temperatures above 100C they become somewhat mallable
melting point is 419.5C
boiling point is 908C
density is 7.14 grams
2.5 hardness on the mohs scale Zinc Chemical Properties:
Fairly active
dissolves in both alkalis and acids
Doesn't reactive with oxygen in dry air
In moist air is reactions to form zinc carbonate, which forms a thin white crust that prevents further reaction
Burns blue
Isotopes are zinc64-68 and zinc70 Physical Properties:
Shiny metal
Bluish cast
Very soft and can be stretched just with a finger nail
melting point is 321c
boiling point is 765c
density is 8.65 grams
When combined with another metal it lowers the melting point Cadmium Physical Properties:
One of the only liquid metals
Can be frozen at -38.85c
It boils at 365.6c and turns into gas
Density is 13.59 grams
It has a very high surface tension
Very good conductor of electricity Mercury Chemical Properties:
Cadmium reacts slowly with oxygen in moist air at room temperatures, forming cadmium oxide
Does not react with water but does react with most acids
Isotopes, cadmium106, cadmium108, cadmium110, cadmium111, cadmium112, cadmium113, cadmium114, and cadmium116 Physical Properties:
The density is predicted to be 16800 (predicted) kg m-3
Rest unknown Copernicium Chemical Properties:
Unknown Some things zinc is used for:
Used for preventing rush on other metals
It's also used when making alloys such as brass and bronze Some of cadmium uses would be:
Once mainly used for electroplating
Today mainly used in making a special type of battery (Nicad batteries). These batteries can be used over and over again. Chemical Properties:
Mercury is moderately active.
It does not react with oxygen in the air very easily.
It reacts with some acids when they are hot, but not with most cold acids.
Isotopes Hg196, Hg198, Hg199, Hg200, Hg201, Hg202, and Hg203
Mercury is toxic Some uses of mercury are:
The most important use of mercury is making chlorine
The second most important use of mercury in the United States is in switches and other electrical applications
One application in which concerns about mercury have had little effect is fluorescent lamps. A fluorescent lamp contains mercury vapor. When the lamp is turned on, an electricity passes through the vapor (gas), causing it to give off invisible radiation
Mercury batteries are also very popular This element is also very new and a lot is unknown about it as of now, if you want to know more about this element you might want to look at this element in a few months. Examples of these metals! Zinc Cadmium Mercury The liquid in the cup above is mercury, this example shows that mercury has so much surface tension that it can hold up a ball used in pool. THANK YOU FOR WATCHING! These are where the metals are located on the periodic table.
