Which of the following is the first postulate of Bohr's atomic model?

Electron moves in circular orbits around the nucleus

The energy of an electron in a hydrogen atom is quantised

If energy is supplied, electron absorbs the energy and is promoted from a lower energy level to a higher energy level

At excited state, the electron is unstable. It will fall back to lower energy level and releases a specific amount of energy (photon) in the form of light

In Bohr's model of the atom, where are the electrons and protons located?

the electrons orbit the protons, which are at the center of the atom

the electrons and protons move throughout the atom

the electrons and protons are located throughout the atoms, but they are not free to move

the electrons are stationary around the protons, which are at the center of the atom

Emission of light from an atom occurs when the electron ________.

drops from a higher to a lower energy level

moves within its atomic orbital

jumps from a lower to a higher energy level

Which has more energy?

electron moving from the 2 to the 1 energy level

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

gains a certain amount of energy

Which change occurs when an atom in an excited state returns to the ground state?

The number of electrons decreases

The number of electrons increases
