Solved + + WORKSHEET: Chemical Bonding - Ionic & Covalent! | Chegg.com - Free Printable

To solve the problem, we need to determine whether each element in the given compounds is a metal or a non-metal and then identify the type of bond (ionic or covalent) that occurs in each compound. Here's the step-by-step solution:

Key Points to Remember:

1. Ionic Bond: Forms between a metal and a non-metal.
2. Covalent Bond: Forms between two non-metals.

List of Metals and Non-Metals:

- Metals: Typically found on the left side of the periodic table (excluding hydrogen).
- Examples: Mg, Ca, K, Al, Cu, Rb, Fe, etc.
- Non-Metals: Typically found on the right side of the periodic table.
- Examples: N, O, Br, I, Cl, F, S, etc.
