Basic Atoms
The negative subatomic particle
What is an electron?
Multiple of an element that have the same number of protons and a different number of neutrons
What is an isotope?
When atoms tend to form bonds in order to get 8 electrons in their valence shells.

Group 1A
What is an Alkali Metal
Dimitri Mendeleev
