Question

Predict the formula of stable compound formed by an element with atomic number 114 and fluorine.

• A. $A{F}_3$
• B. $A{F}_2$
• C. $AF$
• D. $A{F}_4$

Answer 1

The correct option is D $A{F}_4$

Element A with atomic number 114 will share four electrons to attain stable noble gas electronic configuration. It falls in the Carbon family.

Fluorine shares one electron to attain stable noble gas electronic configuration. One atom of A combines with four atoms of F to form $A{F}_4$.

Hence, the correct option is $\text{D}$
