there are 3 atoms in zinc chloride
Halogens such as fluorine, chlorine, and oxygen readily accept electrons due to their high electronegativity. Transition metals can also readily accept electrons due to their ability to form stable ions with a partially filled d subshell.
The chlorine atoms would become negatively charged because they would gain electrons from the calcium atoms, resulting in an excess of electrons and a net negative charge.
Four chlorine atoms are needed to form a covalent compound with carbon by sharing electrons. Carbon can form four covalent bonds, so it can share one electron with each of the four chlorine atoms to achieve a stable octet electron configuration.

In chlorine gas (Cl2), there are 17 protons and 17 electrons in each chlorine atom. Since there are two chlorine atoms in a molecule of chlorine gas, there are a total of 34 protons and 34 electrons in chlorine gas.
Two atoms of chlorine are needed, one to accept each of the barium electrons in an ionic compound, barium chloride (BaCl2).
No, the chlorine atoms do not return the electrons to the sodium atoms.
Ca + Cl2 --> CaCl2 or Ca2+ + 2 Cl- --> CaCl2

One chlorine atom is needed to form an ionic bond with one magnesium atom because magnesium can donate its two valence electrons to chlorine, which requires one more electron to complete its octet.
