Drawing Lewis Dot Structures

How many electrons should Nitrogen have around its Lewis dot model?

• 1

• 3

• 4

• 5

Reorder the following steps for drawing lewis structures

• The Valence electrons

  charge - add/subtract if there is a charge

• Add remaining electrons as Lone pairs (terminal atoms first).

• Place the lower Electronegative atom in the centre and draw in bonds

• If any atoms dont have an Octet, use electrons to create double bonds.

• Check each atom has the same number of electrons as it started with (formal charge)

Which of the following is the correct Lewis structure for the compound PBr₃?

• structure A

• structure B

• structure C

• structure D
