If lon X has a charge of 2+ and lon Y has a charge of 1-, the chemical the formula of the ionic
Monica [59]

The chemical formula of the ionic compound is XY₂.

<h3>Ionic compounds</h3>
  • Ionic compounds are compounds which are formed from the combination of negatively charged and positively charged ion.
  • Positively charged ions are formed by loss of electrons
  • Negatively-charged ions are formed from gain of electrons

<h3>Formation of ionic compounds</h3>

During the formation of the ionic compound between an ion X that has a charge of 2+ and ion Y has a charge of 1-, two negatively charged ions of Y are required to form a neutral ionic ionic compound when they react with X.

The chemical the formula of the ionic compound they form is as follows;

X²⁺  + 2Y⁻ ---> XY₂

Therefore, the chemical formula of the ionic compound is XY₂.

VLD [36.1K]

Just like how heat moves from a region of higher temperature to a region of lower temperature, molecules also tend to move from a region of higher concentration to a region of lower concentration. This is called natural diffusion and is naturally happening to reach stability.
