200
This group is a highly reactive group of metals
What is Alkali Metals

I help prove that the first periodic table was an excellent model when I was discovered by a French chemist in 1875.
What is gallium
200
Most reactive element with 1 valance electron
What is francium
200
Mendeleev grouped the elements by increasing atomic mass and by placing the elements into similar groups.This is similar to which card game?
What is solitaire
300
We are not very reactive
What is the noble gas group

300
I am a noble gas with only 2 valence electrons instead of 8
What is hellium
300
I have only 2 valance electrons

What is iodine
500
During a stage of making computer chips, pure silicon is heated in a furnace at 1480 degrees Celsius. At this high temperature silicon reacts with both nitrogen and oxygen. Which group on the periodic table allows us to make computer chips?
