Question

Which element, when combined with Fluorine would most likely form a covalent compound?

Aluminum (Al)
Sulfur (S)
Potassium (K)
Calcium (Ca)

Answer 1

Sulphur

Step-by-step explanation:

When Fluorine reacts with Aluminium,
`AlF_(3)` is formed.Since
`Al` is metal and
`F` is non metallic,the compound has ionic nature.

When Fluorine reacts with Sulphur,
`SF_(6)` is formed.Since
`S` is non metal and
`F` is also non metallic,the compound has prevalent covalent nature.

When Fluorine reacts with Potassium,
`KF` is formed.Since
`K` is metal and
`F` is non metallic,the compound has ionic nature.

When Fluorine reacts with Calcium,
`CaF_(2)` is formed.Since
`Ca` is metal and
`F` is non metallic,the compound has ionic nature.
