Question

Give the number of electrons in the species $H_2^{+},H_{2}and{O}_2^{+}$

Answer 1

$H_2^{+}$ :
Number of electrons present in hydrogen molecule ($H_2$) = 1 + 1 = 2
$\therefore$ Number of electrons in $H_2^{+}=2-1=1$

$H_2$ :
Number of electrons in $H_2$ = 1 + 1 = 2

$O_2^{+}$ :
Number of electrons present in oxygen molecule ( $O_2$ ) = 8 + 8 = 16
Number of electrons in $O_2^{+}$ = 16 – 1 = 15
