protons = +1
neutrons = 0
electrons = -1
3
New cards
explain why atoms have an overall neutral charge
protons are positive and electrons are negative.
atoms have equal numbers of protons and electrons.
so the charges sum to zero
4
New cards
define element
a substance that is made of only one type of atom
5
New cards
state the number of electrons that can go in the first shell
two
