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 particles are found in the nucleus of an atom?

Back

The nucleus contains protons and neutrons.

Front

What particles are found in the electron cloud?

Back

The electron cloud contains electrons only.

Front

What is the overall charge of an entire atom?

Back

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

Front

Which region of the atom is divided into energy levels?

Back

The electron cloud is divided into energy levels.

Front

What is the role of protons in an atom?

Back

Protons determine the atomic number and identity of the element.

Front

What is the role of neutrons in an atom?

Back

Neutrons contribute to the mass of the atom and stabilize the nucleus.

Front

What is the significance of electrons in an atom?

Back

Electrons are involved in chemical bonding and determine the atom's charge.

Front

How do protons and electrons compare in terms of charge?

Back

Protons have a positive charge, while electrons have a negative charge.

Front

What is the mass comparison between protons, neutrons, and electrons?

Back

Protons and neutrons have approximately the same mass, which is much greater than that of electrons.
