Question

The charge on ammonium ion is
a) + 3
b) + 2
c) + 1
d) + -1

​

Answer 1

$\huge\underline{\overline{\mid{\bold{\purple{+ 1 }}\mid}}}$

$\huge\underline{\overline{\mid{\bold{\blue{explanation}}\mid}}}$

The sole but crucial difference is that the ammonium ion has one more proton in the nucleus of the central atom and hence an overall charge of +1.
