Subatomic Particles

Vocabulary flashcards covering subatomic particles, their symbols, charges, masses, and locations within or orbiting the atom.

Proton

A subatomic particle with symbol $p^+$, a charge of $+1$ (in multiples of $e$), and a mass of $1.0\,\text{amu}$, located in the nucleus.

Neutron

A subatomic particle with symbol $n^0$, a charge of $0$ (in multiples of $e$), and a mass of $1.0\,\text{amu}$, located in the nucleus.

Electron

A subatomic particle with symbol $e^-$, a charge of $-1$ (in multiples of $e$), and a mass of $0.0005\,\text{amu}$ or about $\frac{1}{1800}\,\text{amu}$, located orbiting the nucleus.
