5.1 Revising the Atomic Model

How many energy levels on the atom?

• 7 Levels

• 2 Levels

• 9 Levels

• 6 Levels

What is a Quantum?

• is the amount the energy required to move an electron from one energy level to another energy level.

• is a subatomic particle, symbol e⁻ or β⁻ , whose electric charge is negative one elementary charge.

• is a subatomic particle, symbol p, with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron.

• is a subatomic particle, symbol n, which has a neutral (not positive or negative) charge, and a mass slightly greater than that of a proton.

What is an electron cloud

• is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei.

• is spherically symmetric around the nucleus of the atom, like a hollow ball made of rather fluffy material with the nucleus at its centre.

• is ​the region of negative charge surrounding an atomic nucleus that is associated with an atomic orbital.
