Cards in this deck (11)
- 1Atomic NumberNumber of protons in the nucleus of an Atom.
- 2Mass NumberTotal number of protons and neutrons in the nucleus.
- 3IsotopesAtoms of the same element, same atomic number, but have different mass numbers.
- 4Relative Isotopic MassThe mass of a single isotope of an element relative to 1/12, the mass of carbon-12
- 5Relative Atomic MassThe avg. mass of an element relative to 1/12, the mass of carbon-12. Including all its Isotopes.
- 6Relative Molecular MassThe mass of a single molecule relative to 1/12, the mass of carbon-12.
- 7Energy LevelsThe energy levels/shells which the electrons orbit around the nucleus.
- 8Sub-shellsEnergy Levels are divided into sub-shells which are made of orbitals, the way the electron moves around the nucleus of the atom.
- 9IsoelectronicParticles which have the same electron configuration.
- 10IonisationThe Process of removing electrons from energy levels surrounding an atom.
- 11First Ionisation EnergyThe amount of energy required to remove 1 mole of electrons from 1 mole of gaseous atoms to form one mole of gaseous ions.
