Type of molecule

Question 1

Ionic Solids

Answer 1

Composed of a regular 3D pattern or lattice of positive and negative ions (cations and anions) held in place by strong electrostatic attractions or ionic bonds.

Question 2

Sillica

Answer 2

3D covalent network made up of silicon atoms covalently bonded to 4 oxygen atoms in a tetrahedral shape.

Question 3

Graphite

Answer 3

is a covalent network solid made up of a 2D arrangement of carbon atoms covalently bonded, each carbon is bonded to three others with a lone pair. Sheets of graphite bonded together by weak intermolecular forces.

Question 4

Diamond

Answer 4

is a covalent network solid made up of a 3D array of of carbon atoms covalently bonded to four other carbon atoms in a tetrahedral arrangement.

Question 5

Molecular Solid

Answer 5

composed of molecules bonded together by weak intermolecular forces in a lattice structure

Question 6

Metallic solids

Answer 6

composed of cations bonded by strong non directional bonds in a 3D lattice surrounded by a sea of delocalized electrons.
