Answer:
Neutrons
Explanation:
Isotopes are variations of an element that differ from the number of neutrons.
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:
Global warming and climate change can cause habitats to no longer suit animals needs and not all animals can easily adapt. Climate change can kill if severe enough
Differences<span>: </span>Ionic bonding<span> occurs </span>between<span> atoms that have opposite needs for electrons (metals and nonmetals) and results in a transfer of electrons.</span>Covalent bonding<span> occurs </span>between<span> atoms that have similar needs for electrons (two nonmetals) and results in a sharing of electrons.
