Question

When one atom of hydrogen (H) combines with one atom of bromine (Br), their bonding results in a molecule of HBr. Which of the following describes the arrangement of valence electrons in a bond between H and Br? (My answer: D)


The valence electrons are shared equally between H and Br.

The valence electrons spend more time around the atom of H.

The valence electrons spend more time around the atom of Br.

The valence electrons are given up by the H and gained by the Br

Answer 1

Answer:

C

Explanation:

we can see the answer with the values of electronegativity.

H =2.2

Br=2.96

difference=0.76

So the bond between the H and Br is polar covalent. Both shared the electrons but the electronic cloud stays more in the Br. so the answer is C because Br is more electronegative than H.
