This total energy is influenced by factors such as temperature, pressure, and chemical composition.
The amount of energy needed to move an electron from one energy level to another is an?
The amount of energy needed to move an electron from one energy level to another is known as the energy difference between the two levels. This energy difference is typically quantified in electron volts (eV) or joules.
The ability of an atom in a molecule to attract electrons is best quantified by the what?
The ability of an atom to attract electrons in a molecule is best quantified by its electronegativity. Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.
What is pH mean?
