Check the statements that are a part of the early atomic theory. check all of the boxes that apply. scientists believe that the atom is made up of elements. atoms combine in whole number ratios to form compounds. atoms cannot be created or destroyed during a chemical reaction.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
