Question

Using the periodic table, predict the charges of the ions of the following element: 

(d) Br

Video Transcript

Alright guys, so here we have to predict the charge of the element. Our element is bromine, where is bromine located? Bromine is going to be located in group 7A, group 7A element are just 1 electron away from reaching the noble gas configuration. So we need to gain 1 electron, so how do we write that we need to gain 1 electron, well gaining electron means a minus charge.

Losing an electron means a positive charge, because when you're gaining electrons negatively charged you're becoming more negative and if you're losing electrons which is a positively charge that means that you're becoming more positive. So here this is going to be Br minus. Alright guys, lets move on.
