General chemistry
Molecular geometry
Chemistry; General chemistry
1. The three-dimensional shape of a molecule. For example, methane (CH4) has a tetrahedral molecular geometry. 2. The study of molecular shapes. molecular model stick model; ball and stick model; ...
Surface tension
Chemistry; General chemistry
The work required to expand the surface of a liquid by unit area.
Adiabat
Chemistry; General chemistry
A line on an indicator diagram that represents an adiabatic process.
Effective nuclear charge
Chemistry; General chemistry
The nuclear charge experienced by an electron when other electrons are shielding the nucleus.
Molecular orbital
Chemistry; General chemistry
A wavefunction that describes the behaviour of an electron in a molecule. Molecular orbitals are usually spread across many atoms in the molecule, and they are often described as a combination of ...
Surfactant
Chemistry; General chemistry
A material that spreads along a surface, changing the properties of the surface. For example, soap spreads over a water surface and lowers its surface tension .
Adiabatic
Chemistry; General chemistry
A process that neither absorbs nor releases energy into the surroundings. For example, a chemical reaction taking place in a closed thermos bottle can be considered adiabatic. Very fast processes can ...
