2-1 Flashcardizz Part 1 Subatomic Particles & Parts of Atom

Front

What charge does the electron cloud have?

Back

The electron cloud has a negative charge because it contains electrons (e^-).

Front

What charge does the nucleus have?

Back

The nucleus has a positive charge because it contains protons (p⁺) and neutrons (n^o).

Front

What is the overall charge of an entire atom?

Back

The entire atom has a neutral charge because the positive charge of the nucleus cancels out the negative charge of the electron cloud.

Front

Which region of the atom is divided into energy levels?

Back

The electron cloud is divided into energy levels.

Front

What does the electron cloud contain?

Back

The electron cloud contains electrons only.

Front

What are the three main subatomic particles?

Back

The three main subatomic particles are protons, neutrons, and electrons.

Front

Where are protons located in an atom?

Back

Protons are located in the nucleus of an atom.

Front

Where are electrons located in an atom?

Back

Electrons are located in the electron cloud surrounding the nucleus.

Front

What is the mass of a neutron compared to a proton?

Back

A neutron has approximately the same mass as a proton.

Front

What is the charge of a neutron?

Back

A neutron has no charge; it is neutral.
