Question 1

Bonds

Answer 1

Links hat join atoms together

Question 2

Covalent bonding

Answer 2

The sharing of electrons between atoms of non-metal

Question 3

Inert gases

Answer 3

Also known as nobles gases, group 18 elements known for their stability(lack of reactivity

Question 4

Ionic bonding

Answer 4

Attraction of positive and negative ions formed from the transfer of electrons from metallic to non-metallic atoms

Question 5

Ions

Answer 5

‘Charged atoms’ (or a group of atoms) formed by electrons begging transferred from on atom to another

Question 6

Lattices

Answer 6

A regular arrangement on particles. In ionic lattices the particles are io; in solid molecular lattices the particles are molecules

Question 7

Metallic bonding

Answer 7

A mutual attraction between a lattice or posit e metal ions and a sea of delocalised, outer-shell electrons

Question 8

Molecules

Answer 8

Discrete groupings of atoms covalently bonded together

Question 9

Monatomic

Answer 9

Atoms that exist on their own, without bonding with others

Question 10

Noble gases

Answer 10

Also known as inert gases, group 18 elements known for their stability (lack of reactivity)
