Front

What is the Electron Cloud Model?

Back

A model of the atom where electrons are found in regions of space called orbitals, rather than in fixed paths.

Front

What is Nuclear Fission?

Back

A process where the nucleus of an atom splits into smaller parts, releasing a large amount of energy.

Front

What happens during Beta Decay?

Back

A type of radioactive decay where a beta particle (electron or positron) is emitted from an atomic nucleus.

Front

What is the significance of significant figures?

Back

They indicate the precision of a measurement, showing which digits are reliable.

Front

How many significant figures are in the number 100.00?

Back

5 significant figures.

Front

How many significant figures are in the number 100?

Back

1 significant figure.

Front

What is the Bohr Model?

Back

A model of the atom that depicts electrons orbiting the nucleus in fixed paths.

Front

What is the Rutherford Model?

Back

A model of the atom that describes a dense nucleus surrounded by orbiting electrons.

Front

What is the difference between Alpha Decay and Beta Decay?

Back

Alpha decay involves the emission of alpha particles (helium nuclei), while beta decay involves the emission of beta particles (electrons or positrons).

Front

What is Nuclear Fusion?

Back

A process where two light atomic nuclei combine to form a heavier nucleus, releasing energy.
