13 Terms

1

Discrete energy

Emission spectrum representing different possible wavelengths of light emitted by an atom.

New cards
2

Emission spectrum

Series of bright lines representing the wavelengths that can be emitted by an atom.

New cards
3

Radioactivity

Spontaneous emission of particles and energy from an unstable nucleus.

New cards
4

Nuclear transmutation

Transformation of one element to another through nuclear reactions.

New cards
5

Nuclear fission

Splitting of a heavy nucleus into lighter nuclei, with the release of energy.

New cards
6

Critical mass

Minimum mass of fissile material needed to maintain a chain reaction.

New cards
7

Nuclear fusion

Joining of light nuclei to form a heavier nucleus, releasing energy.

New cards
8

Isotopes

Atoms with the same number of protons but different numbers of neutrons.

New cards
9

Radioactive decay

Unstable nuclei emit particles and energy spontaneously.

New cards
10

Half-life

The time required for half the quantity of a radioactive substance to undergo decay.

New cards
11

Unified atomic mass unit (u)

A standard unit of mass for atoms and molecules.

New cards
12

Mass defect

The difference between the mass of separated nucleons and the mass of the nucleus.

New cards
13

Binding energy

The energy required to disassemble a nucleus into its protons and neutrons.
