Ground and excited state of an atom

According to Bohr’s atomic model, for an atom at the ground state, where does an electron exist?

• in nucleus

• in electron cloud

• In the orbit closest to the nucleus

• In the orbit farthest from the nucleus

When an electron moves from a lower energy level to a higher energy level:

• Energy is absorbed, excited state

• Energy is released, excited state

• Energy is absorbed, ground state

• Energy is released, ground state

When an electron moves from a higher energy level to a lower energy level:

• Energy is absorbed, excited state

• Energy is released, excited state

• Energy is absorbed, ground state

• Energy is released, ground state

According to the Bohr model of the atom, which particles are allowed to exist in any one of a number of energy levels?

• protons

• electrons

• neutrons

• both protons and neutrons

The process of an atom releasing energy when it moves to a lower energy state is called

• absorption.

• emission.

• translation.

• regression.
