Atom |
The smallest particles of an element that still retains the identity and properties of the element |
|
|
Ion |
Particle that results when a neutral atom gains or loses electrons |
|
|
Electron affinity |
The energy released when an atom gains an electron |
|
|
Electronegativity |
The attraction an atom has for a shared pair of electron in a covalent bond |
|
|
Atomic radius |
The distance between the center of the nucleus to the valence level of electrons |
|
|
Ionization energy |
The energy needed to remove an electron from an atom |
|
|
Hydrogen 1 Hydrogen 2 Hydrogen 3 (names) |
Protium Deuterium Tritium |
|
|
Average atomic mass formula |
(Mass of isotope 1 * abundance %) + (Mass of isotope 2 * abundance %) |
|
|
Ionic bonding |
Chemical bond formed by the electrostatic attraction between positive and negative ions |
|
|
Covalent bonding |
Occurs when one atom nucleus is unable to completely pull an electron away from the other atom's nucleus |
|
|
VSEPR theory (acronym for?) |
Valence Shell Electron Pair Repulsion theory |
|
|
Ionic (solid aggregate) |
3d crystal lattice structure comprised of ions surrounding by an ion of the opposite charge; continuously alternates |
|
|
Covalent molecular (polar) |
formed by the sharing of electrons by adjacent nuclei due to attraction from both nuclei |
|
|
Covalent network (non polar) |
Giant molecular amount of atom's and branch like structure |
|
|
Metallic |
Cations in a metal are surrounded by delocalized electrons and each free electrons is attracted by an atom |
|
|
Polar covalent bond |
A covalent bond around which there is an uneven distribution of electrons, making one end slightly positively charged and the other end slightly negatively charged. |
|
|
Intermolecular forces |
The attractive forces that exist between molecules or monoatomic atoms of a substance |
