Bonding (Ionic, Covalent & Metallic)

Question 1

What happens in ionic bonding?

Answer 1

A metal loses electrons to form positive ions, and a non-metal gains electrons to form negative ions.

Ionic bonding typically occurs between metals and non-metals.

Question 2

What is a covalent bond?

Answer 2

A shared pair of electrons between two non-metal atoms.

Covalent bonds can be single, double, or triple depending on the number of shared electron pairs.

Question 3

What are metallic bonds?

Answer 3

Positive metal ions surrounded by a sea of delocalized electrons.

This structure allows metals to conduct electricity and heat effectively.

Question 4

What properties do ionic compounds have?

Answer 4

High melting/boiling points, conduct electricity when molten or in solution.

Ionic compounds typically form crystalline structures.

Question 5

What properties do simple covalent molecules have?

Answer 5

Low melting/boiling points, do not conduct electricity.

Simple covalent molecules include substances like water and carbon dioxide.

Question 6

What gives metals their malleability and electrical conductivity?

Answer 6

The presence of delocalized electrons.

This allows metal atoms to slide past each other without breaking the metallic bond.
