Question

Match the following types of bond with their correct example.

• A. Common salt
• B. Water molecule
• C. Iron rod

Answer 1

- Common salt (NaCl) is an ionic compound as sodium being electropositive transfers one electron to the chlorine in order to gain stability.

- Water molecule is a covalent compound since two hydrogen atoms share an electron each with an oxygen atom having six electrons in its outermost shell.

- In an iron rod, a metallic bond is formed between the ${\text{Fe}}^{2+}$ ions and the free moving electrons.
