<u>Answer:</u> The ion formed is _{12}^{26}\textrm{Mg}^{2+}

<u>Explanation:</u>

An ion is formed when an atom looses or gains electron.

  • When an atom looses electrons, it will form a positive ion known as cation.
  • When an atom gains electrons, it will form a negative ion known as anion.

Atomic number is defined as the number of protons or electrons that are present in a neutral atom.

Atomic number = number of protons = number of electrons

Atomic mass is defined as the sum of number of protons and neutrons that are present in an atom.

Atomic mass = Number of protons + Number of neutrons

The isotopic representation of an atom is: _Z^A\textrm{X}

where,

Z = Atomic number of the atom

A = Mass number of the atom

X = Symbol of the atom

We are given:

Number of protons = 12

Number of neutrons = 14

Atomic Mass = 12 + 14 = 26

Number of electrons = 10

As, the number of electrons is less than the number of protons, it forms positive ion

Hence, the ion formed is _{12}^{26}\textrm{Mg}^{2+}
