Question

1. draw the following lewis dot structures using the periodic table. (see companion material, the periodic table, attached.) draw a lewis dot structure for br. draw a lewis dot structure for at.

Explanation:

Step1: Determine valence electrons

Bromine (Br) is in Group 17 of the periodic table, so it has 7 valence electrons.

Step2: Draw Lewis dot structure

We represent the Br atom with its symbol and place 7 dots around it to represent the valence electrons. The dots are placed one - by - one on the four sides (up, down, left, right) of the symbol until all 7 are placed.

Answer:

The Lewis dot structure for Br has the symbol 'Br' with 7 dots around it, with 2 dots on one side and 1 dot on each of the other three sides.
