Definitions - Bonding

Question 1

Element

Answer 1

Substance made form only one type of atom

Question 2

Compound

Answer 2

Substance made from 2 or more types of atom chemically bonded together

Question 3

Molecule

Answer 3

Particle made form two or more atoms chemically bonded together using a covalent bond

Question 4

Ion

Answer 4

Electrically charged particle formed by the loss or gain of one or more electrons from one or atom or group of atoms

Question 5

Ionic bonding

Answer 5

Electrostatic attraction between positive and negative ions (opposite charge)

Question 6

Giant ionic lattice

Answer 6

Structure resulting from oppositely charged ions strongly attracted in all directions e.g NaCl

Question 8

Metal and ionic, Giant

Answer 8

Always giants as they have no covalent bonds and aren’t molecules

Question 9

Simple Vs Giant

Answer 9

Giant - Strong bonds holding structure together
Simple - weak intermolecular forces between molecules

Question 10

Giant ionic lattice

Answer 10

• High melting point - strong electrostatic force of attraction between op charged ions = high energy needed to break
• Can conduct when molten/aqueous - Ions are free to move and carry charge
• Soluble in polar solvents e.g water
