The atomic numbers of \( \mathrm{Co}, \mathrm{Zn} \), and \( \mathrm{Br} \) are, respectively, 27, 30, and \( 35 . \)
(11) In

The atomic numbers of \( \mathrm{Co}, \mathrm{Zn} \), and \( \mathrm{Br} \) are, respectively, 27, 30, and \( 35 . \) (11) In the Zn atom (in its ground state), how many electrons are \( m=-2 \) and \( s=+\frac{1}{2} \) ? (12) In the Zn atom (in its ground state), how many electrons are \( l=1 \) and \( m=-1 \) ? (13) In the \( \mathrm{Br}^{-} \)ion (in its ground state), how many electrons are \( m=0 \) and \( s=+\frac{1}{2} \) ? (14) In the \( \mathrm{Co}^{4+} \) ion (in its ground state), how many electrons are \( l=0 \) ? (15) In the \( \mathrm{Zn}^{2+} \) ion (in its ground state), how many electrons are \( m=0 \) ?
