Question

magnesium
determine the ionic name.
write the chemical symbol and charge.
the ionic charge of is achieved when the atom electrons.

Explanation:

Step1: Determine ionic name

Magnesium loses 2 electrons to form a cation. The ionic name is magnesium ion.

Step2: Write chemical symbol and charge

The chemical symbol of magnesium is Mg. Since it loses 2 electrons, the charge is +2, written as Mg$^{2 + }$.

Step3: Explain how ionic - charge is achieved

Magnesium has an atomic number of 12 and an electron - configuration of 2, 8, 2. It loses 2 electrons to achieve a stable noble - gas electron - configuration. So the ionic charge of +2 is achieved when the atom loses 2 electrons.

Answer:

1. Magnesium
2. Mg, 2+
3. +2, loses, 2
