18. Calcium has atomic number of 20 so the 2+ ion has two less electrons than the neutral elemnt.
What do all of one element have in common?
The same number of protons (the atomic number),(the number of neutrons in the nucleus may differ from atom to atom ) The fact that atoms of an elemnt have the same number of protons means that in the neutral atom the number of electrons is the same - and therefore the chemistry is the same.
Is calcium an elemnt?
Yes, it has the atomic # of 20 on the periodic table of elements.
