Discuss why there wouldn't be an element in between side by side existing elements?
What is that the element on the right should have one more proton than the element on the left.
There can't be half a proton in the nucleus, so there can't be any atomic numbers between existing elements.
1) Metals - shiny, good conductors of electricity and heat, can be shaped easily, almost all are solids at room temp.
2) Non-Metals - dull, poor conductors of electricity and heat, cannot be shaped easily, many are gases at room temp
This is the name given to columns on the Periodic Table
