Unit 1 - Bonding Consolidation

The type of bonding that tends to exist between non-metals only.

In covalent bonding, atoms of non-metals _____ electrons between them.

A small group of atoms bonded covalently is called...

• a metallic lattice

• an ionic lattice

• covalent network

• covalent molecule

Covalent bonds are formed when there is an electrostatic attraction between

• positive and negative ions are attracted to each other

• positive metal ions are attracted to delocalised electrons

• positive nuclei are attracted to a shared pair of electrons

Do covalent compounds conduct electricity?

• Yes

• No

Why can't covalent substances conduct electricity?

• They have delocalised electrons

• The ions are trapped in the bond

• The electrons are trapped in the bond

• They can conduct electricity

The type of bonding that tends to exist between metals and non-metals.

Ionic bonds are formed due to the electrostatic attraction between

• positive nuclei and shared electrons

• positive metal ions and delocalised electrons

• positive and negative ions

When an ​ (a)   bond forms, ​ (b)   tend to be ​ (c)   by metal elements and gained by​ (d)   elements. In doing so they form positive and negative ​ (e)   .

• ionic
• electrons
• lost
• non-metal
• ions
• covalent
• protons
• shared
• metal
• charges

Metals form what type of ions?
