Answer
$\begin{array}
{|c|cccc|}
Symbol & ^{58}Ni & ^{33}S & ^{20}Ne & ^{55}Mn \\
N. of\ protons & 28 & 16 & 10 & 25 \\
N. of\ neutrons & 30& 17& 10 & 30\\
N. of\ elecrons & 28 & 16 & 10 & 25 \\
(neutral\ atom) & \\
Name & Nickel & Sulfur & Neon & Manganese
\end{array}$
Work Step by Step
Relevant information: $Z=p^+=e^-$, $A=Z+n^0$
From the periodic table:
$^{58}Ni$: Nickel, $Z=28, A=58\rightarrow n^0=30$
$^{33}S$: Sulfur, $Z=16, A=33\rightarrow n^0=17$
$p^+=Z=10\rightarrow Ne, Neon$, $n^0=10\rightarrow A=20$
$e^-=Z=25\rightarrow Mn, Manganese$, $n^0=30\rightarrow A=55$
