DISAPPEARING ROCKS EXPERIMENT I am not able to get many of the supplies required for the experiment.
If you have done it, please help me if possible.
I have asked for help on this several times and i have been reported or someone has wasted my time to comment unhelpful things on it and not helped me at all.
If you help me I will mark Brainliest and give 50 points.
Thanx y'all :)

Most animal cells membranes have proteins that pump ions out of the cell and potassium ions into the cell

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
