Review the mass and size of an atom. A typical hydrogen atom, for example, has a mass of 1.66 x 10-24 g. Imagine how big a number we would need to describe the number of atoms in a real-life sample of an element. Could we somehow measure or handle a dozen or a ream of atoms? Explain.

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.

your answer is c) plasma
