WHAT MAKES ELECTRONS JUMP TO OTHER ORBITS AROUND THE NUCLEUS THEN FALL AGAIN

Explanation:

Electrons absorb energy in photons. This makes the eclectron excited. An electron in an excited state can release energy and fall to a lower orbit

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.

explanation:

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
