What’s are electrons
Hang around side the nucleus have no mass and the charge is 1-
What are protons?..
In the nucleus mass 1 charge +1
What are neutrons?
In nucleus mass of 1 no charge or neutral.
What are the electrons on the outer ring called.
Valence electrons.
What’s an isotope?
An atom with a different number of neutrons, giving it a different mass.
What does an atom become when either electrons are added or taken away? It gives it a charge.
Ion
What is the formula for finding atomic mass
Protons+neutrons
How do you get the charge of an atom?
Protons-electrons
