1 g) Covalent Bonding

Question 1

Covalent Bonding

Answer 1

Strong electrostatic force of attraction between the nuclei of the atoms making up the bond and the shared pair of electrons.

Question 2

Delocalised Electrons

Answer 2

Electrons that are no longer attached to particular atoms or pairs of atoms, but are free to move throughout the whole structure.

Question 3

Intermolecular Force

Answer 3

Force of attraction between covalent molecules, much weaker than covalent bonds within the molecules.

Question 4

Allotropes

Answer 4

Different forms of the same element.

Question 5

Dot-and-Cross Diagram

Answer 5

Representation of how electrons are arranged.

Question 6

Double Bond

Answer 6

Atoms sharing two pairs of electrons in a covalent bond.

Question 7

Electrostatic Attraction

Answer 7

Force of attraction between something that is positive and something that is negative.

Question 8

Giant

Answer 8

Structure in which there are no individual molecules and the bonding extends in all directions.

Question 9

Hydrogen halide

Answer 9

Compound formed between hydrogen and a halogen.

Question 10

Simple Molecular Structures

Answer 10

Consists of molecules in which the atoms are joined by strong covalent bonds but which have weak intermolecular forces between the molecules.

Question 11

Triple Bond

Answer 11

Atoms sharing three pairs of electrons in a covalent bond.
