How many atomsl# of particles of Hydrogen are
there in 2 moles of Hydrogen?
(hint this is not a small
number)

1.204×10^24 atoms

Explanation:

1 mole of element contains 6.02×10^23 atoms so 2 moles of hydrogen contains 2×6.02×10^23 = 1.204×10^24 atoms

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
