2-1Flashcardizz Part 7: The Nucleus vs. Electron Cloud

Front

What are protons and neutrons?

Back

Protons and neutrons are subatomic particles found in the nucleus of an atom. Protons have a positive charge, while neutrons have no charge.

Front

What is the electron cloud?

Back

The electron cloud is the region around the nucleus of an atom where electrons are likely to be found. It is mostly empty space.

Front

What is the charge of electrons?

Back

Electrons have a negative charge.

Front

How do electrons behave in the electron cloud?

Back

Electrons repel each other due to their like charges but are attracted to protons in the nucleus due to opposite charges.

Front

What determines the mass of an atom?

Back

The mass of an atom is primarily determined by the number of protons and neutrons in its nucleus.

Front

What is the relationship between the nucleus and the electron cloud?

Back

The nucleus contains protons and neutrons, while the electron cloud surrounds the nucleus and contains electrons.

Front

What is the significance of the electron cloud in determining atomic size?

Back

The electron cloud determines the size of an atom because it represents the space occupied by electrons.

Front

What happens to the forces between electrons and protons?

Back

Electrons are attracted to protons due to opposite charges, while they repel each other.

Front

What is the role of neutrons in the nucleus?

Back

Neutrons help stabilize the nucleus by offsetting the repulsive forces between protons.

Front

What is the concept of atomic mass?

Back

Atomic mass is the weighted average mass of an atom's isotopes, reflecting the number of protons and neutrons.
