Step by step solution

Given Information

We need to complete the table.

Simplify

Selenium- $\begin{matrix} 34 \\ 16 \end{matrix} S e$

number of protons- $16$

number of neutrons- localid="1652015569429" $34 - 16 = 18$

number of electrons- $16$

Nikal- localid="1652016060903" $\begin{matrix} 62 \\ 28 \end{matrix} N i$

number of protons- localid="1652016063894" $28$

number of neutrons- localid="1652016067073" $34$

number of electrons- localid="1652016070565" $28$

Magnesium localid="1652016073400" $\begin{matrix} 26 \\ 12 \end{matrix} M g$

number of protons- $12$

number of neutrons- localid="1652016077675" $14$

number of electrons- localid="1652016081839" $12$

Radium localid="1652016086033" $\begin{matrix} 288 \\ 28 \end{matrix} R a$

number of protons- localid="1652016090956" $88$

number of neutrons- localid="1652016094789" $228 - 88 = 140$
