Question

write the chemical symbol, including the charge, for the common anion formed by bromine, br.
part: 2 / 3
part 3 of 3
draw the lewis dot symbol for the common anion formed by bromine, br.

Explanation:

Step1: Determine bromine's group

Bromine is in group 17 (halogens), has 7 valence - electrons.

Step2: Find the anion formed

It gains 1 electron to achieve a stable octet, forming an anion with a - 1 charge.

Step3: Write the chemical symbol

The chemical symbol for the bromine anion is $Br^-$.

Step4: Draw the Lewis - dot symbol

The Lewis - dot symbol for $Br^-$ has the symbol $Br$ surrounded by 8 dots (representing 8 valence electrons) and a $1 -$ charge outside the brackets: $[\ddot{Br}:]^-$

Answer:

Part 1: $Br^-$
Part 3: $[\ddot{Br}:]^-$
