an ionic bond
Each fluorine atom has 9 protons.
They will not bond
A calcium atom contains 20 electrons and is electrically neutral. A calcium ion contains only 18 electrons and is positively charged.
Neon has 10 protons and 10 electrons. Calcium has 20 protons and 20 electrons.
Calcium is an element, so each atom of calcium is calcium.
A calcium atom will readily form Ca2+ ions while a chlorine atom will readily form Cl- atoms. Thus, ionic bonding is the only bonding that can occur between a calcium and a chlorine atom. The equation for the reaction is as follows: Ca + Cl2 --> CaCl2
calcium atom have 20 electrons.
calcium atom as calcium ion will lose two electrons from the last shell so the atomic radius will decrease in calcium ion than calcium atom.
