Over time Pangaea broke apart to form other continents. Which group of modern-day continents composed Gondwanaland?
Africa, South America, Antarctica, Australia, and the subcontinent of India
North America and South America
O Antarctica, South America, and Europe
North America, Europe, and most of Asia

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

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: )
