Bonding

Question 1

What is an ion?

Answer 1

An atom or group of atoms that has an electrical charge, either positive or negative

Question 2

How is an ion formed?

Answer 2

Atoms with incomplete outer electrons shells are unstable. Atoms must lose or gain electrons in order to become stable

Question 3

How to know if it’s positively or nagativley charged?

Answer 3

If an atom gains electrons, it becomes negatively charged. If it loses electrons, it becomes positively charged

Question 4

What is ionic bonding?

Answer 4

The electrostatic force between oppositely charged ions. It forms giant ionic lattices

Question 5

What is covalent bonding?

Answer 5

The electrostatic force between the nucleus and a bonding pair of electrons. It forms simple covalent or giant covalent molecules

Question 6

What is metallic bonding?

Answer 6

The electrostatic force between the positive ions and delocalised electrons. It forms giant metallic lattices
