How do valence electrons impact the type of bonds an atom makes? An atom wants an empty outer shell of valence electrons, so it will either transfer or share electrons depending on what the other atom needs.
A large number of valence electrons means the atom will share electrons; a small number of valence electrons leads to transferring from one atom to another.
A small number of valence electrons means the atom will share electrons; a large number of valence electrons leads to transferring from one atom to another.
An atom wants a full outer shell of valence electrons, so it will either transfer or share electrons depending on what the other atom needs.

Use your knowledge of valence electrons and how they affect bonds to figure out how carbon (Group 14) and oxygen (Group 16) would be attached to one another. In carbon dioxide (CO2), how is the compound structured? (Use “–” to represent a single bond and “=” to represent a double bond.)(1 point)
O=C=O
C=O–O
C–O–O
O=C–O

Methane’s chemical formula is CH4. Is there a bond between any of the hydrogen atoms? Why or why not?
Yes, there is because there are one too many hydrogen atoms for carbon to handle alone, so one hydrogen must bond with another.
No, there is not because carbon needs four bonds, so it bonds with each hydrogen atom; hydrogen only forms one bond.
No, there is not because it would form H2 instead of methane if hydrogen bonded with itself.
Yes, there is because they form a long chain in order to all have stable outer energy shells.

In hydrogen peroxide (H2O2), which option best shows how the atoms are ordered?
H–O–O–H
O–H–H–O
H–O–H–O
O–H–O–H
