Select the correct answer. What is the molar mass, in grams, of a mole of an element equal to?
ОА
the number of electrons in the element
ОВ.
the atomic weight of the element
O c.
the atomic number of the element
D.
the number of neutrons in the element

c (diamond),

sio2 (quartz)

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
