Take this Quiz: GCSE Chemistry: Ionic, Covalent and Metallic Bonding | Zestly

Question 1

Which of the following statements correctly describes the formation of an ionic bond?

Accepted Answer

Electrons are transferred from a metal atom to a non-metal atom.

Question 2

Which ions are typically formed by elements in Group 2 and Group 7 of the periodic table, respectively?

Accepted Answer

Group 2 forms $2+$ ions; Group 7 forms $1-$ ions.

Question 3

Which of the following properties are characteristic of simple covalent molecules?

Accepted Answer

Low melting and boiling points

Question 4

In a metallic bond, what is the nature of the 'sea of electrons'?

Answer

Electrons are fixed in place between two specific metal nuclei.

Answer

Electrons are delocalised and free to move throughout the metal structure.

Answer

Electrons are transferred from the metal to a non-metal to form a lattice.

Answer

Electrons are shared equally between two non-metal atoms.

Question 5

Which of the following statements accurately describe the properties of giant ionic lattices?

Answer

They have high melting points due to strong electrostatic forces.

Answer

They conduct electricity when in a solid state.

Answer

They are generally soft and easily deformed.

Answer

They conduct electricity when dissolved in water or molten.
