Bonding and Structure

Question 1

Ionic bond

Answer 1

A bond where a positive ion donates an electron to a negative ion. Bond between metal and non-metal

Question 2

Covalent bond

Answer 2

A bond where two atoms share electrons to form a molecule. A bond between two non-metals

Question 3

Properties of ionic lattices

Answer 3

Very high melting and boiling points, can conduct electricity if in liquid form because the particles can move freely

Question 4

Properties of covalent bonds

Answer 4

Gases at room temperature except water, weak intermolecular forces, strong covalent bonds, don’t conduct electricity because no free electrons

Question 5

Properties of giant covalent molecules

Answer 5

High boiling and melting points due to many covalent bonds, cannot conduct electricity due to no free electrons
