04.06 The Periodic Table of Elements
Transcript of 04.06 The Periodic Table of Elements
A list of five compounds the element can form:
It can form into technetium, promethium, neptunium, plutonium, and americum are all compounds of oxygen.
Identify whether each compound is only naturally occurring, only human–made, or both naturally occurring and human–made:
Each of the compounds are naturally made.
A brief description of how the element was discovered, identified, and/or purified:
A French chemist named Antoine Lavoisier first discovered oxygen in 1775. He was the first to recognize it as an element, and coined its name "oxygen" - which comes from a greek word that means "acid former". The number of valence electrons in a neutral atom of the element = 8.
A description of the element's position on the periodic table, including a list of other elements that have similar properties (if any)- Oxygen's position on the periodic table is in group 16, period 2, and in the series of nonmetals. Elements that have similar properties to oxygen are selenium, sulphur, tellurium, and polonolium. The chemical symbol, average atomic mass, and atomic number for the element:
Chemical Symbol- O
Average Atomic Mass-15.9994 amu
Atomic Number- 8 The name of the element, including an explanation for the origin of its name if that origin is known:
The word oxygen is actually originated from Greece. The real meaning of the word is "that which makes acid". When oxygen was first isolated in air its role or importance was not known and it was treated as any other new element. That is why it's meaning is what it is. A description of where the element is commonly found in nature:
This element (oxygen) is commonly found in water, plants, and also in humans.
A description of how the element is commonly used by people and what properties make it appropriate for that use:
People commonly use oxygen for breathing. If we did not have oxygen then we would be unable to breath, and live. We and all other things would die. All of the properties of oxygen make it appropriate for this use.
