In element notation A is the

Mass number

In element notation, Z is the

Atomic number

Blank is the weighted average of the masses of an elements isotopes

Atomic weight

The blank model states that an atom is mostly empty space with electrons orbiting a fixed, positively charged nucleus

Rutherford model

According to the blank model, electrons orbit the nucleus in orbits that have a set size and energy

Bohr model

The blank principle states that it is impossible to know the momentum and position of an electron simultaneously

Heisenberg uncertainty Principle

Blank states that all orbitals must first have one electron before any orbitals can obtain a second electron

Hund's Rule

The blank principle states that no two electrons can share the same for identical quantum numbers

Pauli Exclusion Principle

Avogadro’s number =

6.022 x 10²³ particles per 1 mole

Planck’s constant (h) =
