electrons in atoms

the ways in which electrons are arranged around the nuclei of atoms

• atomic orbitals

• energy level

• electron configurations

• photoelectric effect

the ejection of electrons by metals when light shines on them

• quantum

• photoelectric effect

• hund's rule

• pauli exclusion principle

the region around the nucleus of an atom where an electron is likely to be moving

• atomic orbitals

• energy levels

• quantum

• electron configurations

an atomic orbital may describe at most two electrons

• hund's rule

• aufbau principle

• quantum mechanical model

• pauli exclusion principal

the regions within which electrons have the highest probability of being found

• atomic orbitals

• quantum

• energy level

• photons

when electrons occupy orbitals of equal energy, one electron enters each orbital until all the orbitals contain one electron

• aufbau principle

• pauli exclusion principle

• hund's rule

• quantum mechanical model

the amount of energy required to move an electron from its present energy level to the next higher one

• photons

• atomic orbitals

• quantum

• energy levels

light quanta

• quantum

• energy level

• photons

• atomic orbitals

electrons enter orbitals of lowest energy first

• aufbau principle

• photoelectric effect

• quantum mechanical model

• hund's rule

the modern description of the electrons in atoms
