An unknown element is a nonmetal and has a valence electron configuration of ns²np⁴.

a. How many valence electrons does this element have?

b. What are some possible identities for this element?

c. What is the formula of the compound this element would form with potassium?

d. Would this element have a larger or smaller radius than barium?

e. Would this element have greater or smaller ionization energy than fluorine?

Expert Solution

a. How many valence electrons does this element have?

answer: 6

b. What are some possible identities for this element?

answer: Oxygen(O) ,Sulfur(S),Selinium(Se),Telurium(Te)

c. What is the formula of the compound this element would form with potassium?

answer: with potassium , oxygen forms compound- K2O (potassium oxide)

d. Would this element have a larger or smaller radius than barium?

answer: smaller radius, in periodic table left to right atomic radius decreases.and top to bottom radius increases.

e. Would this element have greater or smaller ionization energy than fluorine?

answer: as it is bigger in size compared to flourine, its ionisation enrgy is lesser than F.
