Question

question 1 (1 point)
the number of electron groups exists in the valence shell of the boron atom in the bcl₃ molecule is?
1
2
3
4
5

Explanation:

Boron in \(BCl_3\) has 3 valence electrons. It forms 3 single bonds with chlorine atoms, using all valence electrons. There are no lone pairs on boron. Each bonding pair counts as one electron group, so total electron groups = number of bonding pairs = 3.

Answer:

3
