(b–d) The two lone pairs (red lines) in ClF 3 have several possible arrangements, but the T-shaped molecular structure (b) is the one actually observed, consistent with the larger lone pairs both occupying equatorial positions. Step 1: write the configuration of element and then show the valence elactrons around the symbol of element . In such cases (e.g. 2, 3, 1. If an atom has lone pairs, the unpaired electrons will either form bonds, be lost, or the atom will gain electrons to be in a more stable state. Lone pair is a pair of electrons that are not in a bond. Di-bromodimethylselenium (CSD refcode RIZMIW) has 5 electron pairs (4 bonding pairs, and 1 lone pair), the parent shape is therefore trigonal-bipyramidal. Top.
