Revising the Atomic Model 5 - Post

When an electron moves from a lower to a higher energy level, the electron

• always doubles its energy. B

• absorbs a continuously variable amount of energy

• absorbs a quantum of energy

• moves closer to the nucleus.

What is the maximum number of electrons in the second principal energy level?

• 2

• 8

• 18

• 32

How does the energy of an electron change when the electron moves closer to the nucleus?

• It decreases.

• It increases.

• It stays the same.

• It doubles.

The quantum mechanical model of the atom

• defines the exact path of an electron around the nucleus.

• was proposed by Niels Bohr.

• involves the probability of finding an electron in a certain position.

• no longer requires the concept of energy levels.

What is the maximum number of f orbitals in any single energy level in an atom?

• 1

• 3

• 5

• 7
