Covalent Bomds

Question 1

What is a covalent bond

Answer 1

An electrostatic attraction between a shared pair of electrons

Question 2

How do covalent bonds form in terms of electronic structure

Answer 2

Covalent bonds form when two atoms share electrons (in their valence shell) to achieve a stable electron configuration.

Question 3

How can double and triple covalent bonds form

Answer 3

Double and triple covalent bonds form when two or three pairs of electrons are shared between two atoms. For example O(2).

Question 4

Describe a double bond in a diatomic molecule

Answer 4

A double bond in a diatomic molecule occurs when two atoms share two pairs of electrons. This type of bond is common in molecules like oxygen (O₂)

Question 5

Suggest how properties of a double bond could be different to the properties of a single bond

Answer 5

Strength: A double bond is stronger than a single bond because it involves the sharing of two pairs of electrons. This also means it needs a high M and B point
