a double helix structure. Which process of science were
they most likely using?
o publishing results
o repeating an experiment
o constructing a model
. developing procedures

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.
