Homework Answers
6)
Bromine is in group 7 of periodic table.
It has 7 valence electrons.
It needs one more electron to complete its octet.
So, it will accept one more electron and becomes anion with charge of -1
Answer: C
7)
Atomic size decreases as we move from left to right in a period. This is because one extra proton is added.
So, atom in group 1 will be largest.
This element is Rubidium
