Draw a Bohr model showing the number of
protons and neutrons and the electron
arrangement (including pairs and single
electrons) for these atoms.
(a) hydrogen-1
(b) hydrogen-2
(c) beryllium-9
(d) magnesium-26
(e) sulfur-36

pie chart because it is in percents ( % )

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg

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: )
