Answer 2

Final answer: The cation and anion which constitute the magnesium oxide, are $Mg^{2+}$ and $O^{2-}$.    

Given that: We are given magnesium oxide.​

To find: We have to find the anion and cation which constitute the molecule of magnesium oxide.​

Explanation:

• A cations is positive charged ions, which are formed when an atom loses one or more electrons results in an overall positive charge.

Hence cations contain more protons than electrons.

Example:  $H^{+}, He^{2+}, Li^{2+}, Mg^{2+}$

• An anions is negatively charged ions which are formed by gaining one or more electrons results in an overall negative charge.

Hence anions contain more electrons than protons.

Example:  $OH^{-}, F^{-}, Cl^{-}$

• Chemical formula of magnesium oxide is $MgO$.

• Atomic number of magnesium = 12

Electronic configuration = $1s^{2}2s^{2}2p^{6}3s^{2}$

Magnesium donate two electrons from $3s$ orbital and form "$+2$" cation.

• Atomic number of oxygen = 8

Oxygen need two electrons to attains noble gas configuration and become a "$-2$ "charge. Hence it is an anion.

• Cation: $Mg^{2+}$

• Anion: $O^{2-}$

• The cation and anion which constitute the magnesium oxide, are $Mg^{2+}$ and $O^{2-}$.
