Mg+2.
Magnesium is the cation and sulfur is the anion.
Magnesium will form a positive ion during ionic bonding. It will lose 2 electrons to achieve a stable octet configuration, resulting in a 2+ ion. Sulfur typically forms a negative ion by gaining 2 electrons to achieve a stable electron configuration.
When an atom loses an electron, it becomes positive (Since you're taking away something that is negative). It would not become an ion, it would become a cation.
No, nitrogen does not become a negative ion before bonding. Nitrogen typically forms covalent bonds, in which it shares electrons with other atoms.
The magnesium ion (Mg2+) is smaller than the sodium ion (Na+) because as atoms lose electrons and become positively charged ions, they lose electron shells, making them smaller. The higher charge of the magnesium ion also pulls the electrons closer to the nucleus, further reducing its size compared to the sodium ion.

chlorine
When an atom loses an electron, it becomes positive (Since you're taking away something that is negative). It would not become an ion, it would become a cation.
The interactive force between particles in magnesium fluoride is ionic bonding. Magnesium and fluorine atoms transfer electrons to achieve a stable configuration, resulting in the formation of a strong electrostatic attraction between the positively charged magnesium ion and the negatively charged fluoride ion. This creates a stable crystalline structure in magnesium fluoride.
It would just be called an ion of magnesium. There is only one oxidation state for magnesium.
No
No, aluminum does not become a negative ion; like all metals, it forms a positive ion.
No, nitrogen does not become a negative ion before bonding. Nitrogen typically forms covalent bonds, in which it shares electrons with other atoms.
Chlorine becomes a negative ion in the process of bonding; ionization and bonding are simultaneous, so no, it does not happen before bonding.
No, I would expect a chlorine ion to be slightly larger than a magnesium ion. Chlorine gains an electron to form a chloride ion, which increases its electron cloud size, while magnesium loses electrons to form a magnesium ion, making it slightly smaller due to the loss of electron shielding.
No. Helium is a noble gas. It does not want to gain or lose electrons as it already has a full valence shell. In order to become a positive ion it would need to lose an electron.
