Help with this question plsss

The atomic number tells us how many protons and electrons are in the element we are looking at.

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.

the dissolution of polymer can be thermodynamically described in 2 steps.
