PS 4.3 Formative

What was the difference between Bohr's model and Rutherford's model

• Bohr's model focused on the electrons

• Bohr's model focused on the protons

• Bohr's model focused on the neutrons

• Bohr's model focused on the nucleus

The possible energies that electrons in an atom can have are called

• energy levels

• atomic clouds

• energy clouds

• orbital nuclei

An electron in an atom can move from one energy level to another when the atom gains or loses energy.

In our modern atomic model, electrons move around the nucleus like planets in a solar system.

• true

• false

An _____ _____ is a visual model of the most likely locations for electrons in an atom.

An _____ is a region of space around the nucleus where an electron is likely to be found.

What is the maximum number of electrons in the 2nd energy level of an atom?

When all of the electrons in an atom have the lowest possible energies, the atom is said to be in its

• ground state

• orbital configuration

• energy level

• cloud state

The most stable electron configuration is the one in which the electrons are in orbitals with the lowest possible energies.
