• 4

• 6

• 8

How many orbitals are present in d-orbital?

• 1

• 3

Where are the electrons usually found according to the atomic theory?

• In the atomic nucleus.

• Outside the nucleus, most of an atoms’ volume is the electron cloud.

• Outside the nucleus, yet near it because they are attracted to protons.

• Anywhere they want to be – no particular location is more likely than any other.

• p orbital, f orbital, s orbital, d orbital

• s orbital, d orbital, f orbital, p orbital

• s orbital, p orbital, d orbital f orbital

• 4

• 5

What was the key feature of Bohr’s model of the atom?

• Electrons move randomly in the atom.

• Electrons revolve in fixed orbits around the nucleus.

• The atom is a solid sphere

• Electrons are spread evenly throughout the atom.
