Transcript of Metals and Non metals project

METALS AND NON METALS
By: Elijah Pascal Carter
What is an element?
A chemical element is a pure chemical substance consisting of one type of atom distinguished by its atomic number, which is the number of protons in its nucleus. Elements are divided into metals, metalloids, and non-metals
Periodic Table of Elements
A chart of the chemical elements that displays them in rows horizontally in order of increasing atomic number and vertically according to similarity of the chemical properties of their atoms. The position of an element on the table thus gives useful information about the structure and chemical properties of the element. It determines whether the element is a metal, non metal or a metalloid.
Dmitri Ivanovich Mendeleev 27 January 1834 – 20 January 1907) was a Russian chemist and inventor. He formulated the Periodic Law, used to classify the elements. For his contribution, an element was named after him.
Metals
Physical Properties
Ductile
Magnetic
Opaque
Malleable
Lustrous
Good conductor of heat
Solid at room temp
Sonorous
Chemical Properties
Corrodes
Good reducing agent
Forms basic oxides
Loses electrons easily
Metals and Non Metals
Physical Properties Exceptions
Most metals are silvery gray except for gold and copper with their yellow/orange luster
Alkali metals such as lithium, potassium and sodium are soft that they can be cut by a knife.
Metals are solid at room temp except for Mercury
Some non metals like graphite and iodine exhibit metallic luster
Graphite, an allotrope of Carbon (NM) is also a good conductor of electricity
Diamond, another allotrope of Carbon is the hardest natural substance known to man. It also exhibits a high melting point.
Non Metals
Physical Properties

Not ductile
Dull
Brittle
Gas or liquid at room temperature
Transparent
Poor conductor of heat and electricity
Not sonorous
Chemical Properties
Form acidic oxides
Good oxidizing agents
Readily gain or share electrons
Have higher electronegativities
Metals
Everyday Uses
Copper for wiring
Titanium for joint replacement
Gold and Silver for jewelry
Aluminum for packaging, cooking utensils
Calcium for bone strength
Potassium for health supplements
Zinc for protective coat for Iron and sunscreen
Iron for manufacturing automobiles
Cobalt for magnets
Non Metals
Everyday Uses
Nitrogen for explosives
Krypton for lights
Neon for bright signs
Oxygen for breathing
Bromine for camera film
Silicon for glasses
Tellurium for tires
Sulphur for matches and dyes
Graphite in pencils and brake linings
Phosporous for fireworks
Legos and Elements
Building Blocks
Legos are very similar to atoms because they both are the most basic of building blocks.Legos have many colors, shapes and sizes, atoms do too. Each different kind of atom is called an
element
. Each element is unique. Breaking a lego structure to the smallest pieces is like breaking down an object or substance to its most basic form, the atom. While you put legos together to create a structure, atoms bind with other atoms to create a
molecule.
