Arrange the first twenty elements on the periodic table with the relevant velencies

The first 20 elements of the periodic table arranged in order with their relevant valencies (based on common combining capacity from the octet rule):

$$\begin{array}{|r|c|c|} \hline \textbf{Atomic} & \textbf{Symbol} & \textbf{Valency} \\ \textbf{No.} & & \\ \hline 1 & \mathrm{H} & 1 \\ 2 & \mathrm{He} & 0 \\ 3 & \mathrm{Li} & 1 \\ 4 & \mathrm{Be} & 2 \\ 5 & \mathrm{B} & 3 \\ 6 & \mathrm{C} & 4 \\ 7 & \mathrm{N} & 3 \\ 8 & \mathrm{O} & 2 \\ 9 & \mathrm{F} & 1 \\ 10 & \mathrm{Ne} & 0 \\ 11 & \mathrm{Na} & 1 \\ 12 & \mathrm{Mg} & 2 \\ 13 & \mathrm{Al} & 3 \\ 14 & \mathrm{Si} & 4 \\ 15 & \mathrm{P} & 3 \\ 16 & \mathrm{S} & 2 \\ 17 & \mathrm{Cl} & 1 \\ 18 & \mathrm{Ar} & 0 \\ 19 & \mathrm{K} & 1 \\ 20 & \mathrm{Ca} & 2 \\ \hline \end{array}$$

Note: Some elements like N, P, S, Cl show variable valencies in different compounds (e.g., N: 1--5, P: 3,5, S: 2--6, Cl: 1,3,5,7), but the values above are the most relevant/common ones for introductory purposes.

\begin{array}{|r|c|c|}
\hline
Atomic No. & Symbol & Valency \ \hline
1 & H & 1 \ 2 & He & 0 \ 3 & Li & 1 \ 4 & Be & 2 \ 5 & B & 3 \ 6 & C & 4 \ 7 & N & 3 \ 8 & O & 2 \ 9 & F & 1 \ 10 & Ne & 0 \ 11 & Na & 1 \ 12 & Mg & 2 \ 13 & Al & 3 \ 14 & Si & 4 \ 15 & P & 3 \ 16 & S & 2 \ 17 & Cl & 1 \ 18 & Ar & 0 \ 19 & K & 1 \ 20 & Ca & 2 \ \hline
