What happens in an acid-base reaction according to the Arrhenius definition?
A. An acid donates an H', and a base donates electrons.
B. An acid donates an H', and a base donates an OH.
C. An acid accepts an electron pair from a base.
OO
D. An acid donates an H', and a base accepts an H.

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.

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: )
