+## Form a Chemical Bond
+
+Site: LeetCode\
+Difficulty per Site: Easy
+
+## Problem
+
+Two elements can form a bond if one of them is `'Metal'` and the other is `'Nonmetal'`.
+
+Write a solution to find all the pairs of elements that can form a bond.
+
+Return the result table **in any order**. [[Full Description](https://leetcode.com/problems/form-a-chemical-bond/description/)]
+
+## Submitted Solution
