Practice Chemical Bond in Chemistry

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

A lasting force of attraction between atoms that holds them together in molecules, compounds, or crystal lattices, formed when atoms share electrons (covalent bond), transfer electrons (ionic bond), or pool electrons in a metallic sea (metallic bond).

The 'glue' that holds atoms together, made by sharing or transferring electrons.

Example 1

easy
What are the three main types of chemical bonds? Give an example of each.

Example 2

medium
Predict the type of bond formed between: (a) Na and Cl, (b) H and O, (c) C and C. Use electronegativity values: Na = 0.9, Cl = 3.0, H = 2.1, O = 3.5, C = 2.5.

Example 3

easy
Will potassium (K) and bromine (Br) form an ionic or covalent bond? Explain.

Example 4

medium
Why do atoms form chemical bonds instead of always staying separate?
