The particles are no longer held together by the attractive forces keeping it a liquid (hydrogen bonds in the case of water). Enough energy has to be put into the system to break these bonds. When this happens the particles pull apart and fill the space available as a gas
According to Arrhenius definition of acid bases: An acid donates ions in aqueous solution and a base donates hydroxide ions in aqueous solution.
So the given statement that a substance that forms hydroxide ions in aquoeus solution is true.
Example of a base giving hydroxide ions in water:
Answer:
The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive.
The number of protons found in the nucleus equals the number of electrons that surround it, giving the atom a neutral charge (neutrons have zero charge). Most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen.Hoped this helped
Explanation:
To completely describe an electron in an atom, four quantum numbers are needed: energy (n), angular momentum (ℓ), magnetic moment (mℓ), and spin (ms).
