2-1 Flashcardizz Part 3 Stability of Nucleus

Front

What is the stability ratio of protons to neutrons in a stable nucleus?

Back

1:1 (the same amount of protons and neutrons)

Front

Why are protons packed tightly together in the nucleus?

Back

Despite having the same charge.

Front

What type of nuclei do the labeled barrels contain?

Back

Nuclei that do NOT have a 1:1 ratio of protons to neutrons.

Front

What particles are found in the nucleus of an atom?

Back

Protons and neutrons.

Front

What type of nucleus will undergo radioactive decay to achieve stability?

Back

An unstable nucleus.

Front

What is the role of neutrons in the nucleus?

Back

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

Front

What happens to an unstable nucleus during radioactive decay?

Back

It changes its ratio of protons to neutrons to become more stable.

Front

What is the charge of protons?

Back

Positive charge.

Front

What is the charge of neutrons?

Back

Neutral (no charge).

Front

How does the ratio of protons to neutrons affect nuclear stability?

Back

A balanced ratio (close to 1:1) generally indicates stability, while imbalances can lead to instability.
