You have the compound CH4. The first element is a (metal, nonmetal) and the second element is a
(metal, nonmetal). You would predict that this would form a(n).
(ionic, covalent) bond.

1. Nonmetal

2. Nonmetal

3. Covalent

Explanation:

Methane is the molecule being described in this question. It has a chemical formula of CH4 where four hydrogen atoms are bonded to one central carbon atom. Carbon as well as hydrogen are non-metallic elements, which means that they can only share their valence electrons to form a COVALENT BOND.

A covalent bond is a type of chemical bond in which two atoms share their valence electrons. It occurs between two non-metallic atoms. In this molecule, CH4, carbon and hydrogen share their valence electrons to form a covalent bond.

c8h10 is your answerr

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: )
