In ${\mathrm{OF}}_2$ molecule, the number of bond pairs and lone pairs of electrons are $2 \mathrm{and} 8$.

In the Lewis structure, the formal charge on the central atom of ${\mathrm{SnCl}}_3^{-}$ is

Maximum number of lone pairs is present in Lewis dot structure of which compound?

In ${{\mathrm{PO}}_4}^{3-}$ ion formal charge on the oxygen atom of $\mathrm{P}-\mathrm{O}$ bond is

The formal charge on the $\mathrm{O}$-atoms in the ion ${\mathbf{[}\mathbf{:}\ddot{\mathbf{O}}\mathbf{=}\mathbf{N}\mathbf{=}\ddot{\mathbf{O}}\mathbf{:}\mathbf{]}}^{\mathbf{+}}$ is

In which of the following molecule central atom is having complete octet?

Which of the following is not an application of formal charge?

Lewis symbols are used to depict _____ in simple molecules.

The number of dots around the symbol represents the number of _____ electrons.

In ${\mathrm{OF}}_2$ molecule, the number of bond pairs and lone pairs of electrons are:

Which of the following is a Super octet molecule?

Metals lose electrons during ionization. This change is called

Assertion. ${\mathrm{SF}}_6$ is not a stable molecule.

Reason. A stable molecule must have 8 electrons around the central atom, i.e., octet rule should be satisfied.
