Electrons determine THIS about an atom.
What is the charge of the atom?
The elements that have some properties of metals, and some properties of non-metals.
What are metalloids?
This is the octet rule
What is the tendency for atoms to want to have a full valence shell?
This Law of Conservation of Mass says THIS.
What is "matter cannot be created or destroyed"?
It is the same element, but with more or less neutrons.
