Electrons have a negative charge (-1).
Electrons are not part of the nucleus, but they orbit the protons there because protons and electrons have opposite electrical charges.

eletrons
Aluminium lends it's eletrons, it does not borrow it.
By adding or losing eletrons (friction)
count the number of protons which will be equal to number of electron.
electrons are shared in two shells, 2 in the first and 6 in the second
its chemicl reactivily is determined by the number of eletrons in its outer shell property fudamental
Positive charges attract negative charges and repel other positive charges. Negative charges do the opposite, attracting positive charges and repelling other negative charges. Like charges repel and opposite charges attract.
It means that they are charges (that usually refers to electrical charges), and that they don't move (or don't move significantly).
