Cards in this deck (15)
- 1Define atomic numberNumber of protons/electrons
- 2Define diatomicConsisting of two atoms
- 3Define mass-to-charge ratioThe mass divided by the charge of an ion. Often called the m/z value
- 4Define shellA group of atomic orbitals with the same principle quantum number, n. Also known as an energy level
- 5Define sub-shellA sub-division of an energy level (shell). Sub-shells may be s, p, d or f sub-shells
- 6Define orbitalRegions of space around the nucleus of an atom where an electron is likely to be found
- 7Define spinA quantum property of electrons
- 8Define electron configurationThe number of electrons that an atom or ion has, and how they are arranged
- 9Define ionic bondingThe electrostatic attraction between positively charged ions and negatively charged ions
- 10Define giant latticeA regular repeating structure
- 11Define covalent bondingThe strong electrostatic attraction between a shared pair of electrons and the nuclei of the bonded atoms
- 12Define dative covalent (coordinate) bondingA covalent bond in which both electrons come from the same atom
- 13Define average bond enthalpyThe average enthalpy change that takes place when breaking 1 mole of a given bond in the molecule of a gaseous species under standard conditions
- 14Define electronegativityThe ability of an atom to attract the bonding electrons in a covalent bond
- 15Define intermolecular forcesThe forces between molecules
