H2, n2, o2 molecules: must be polar/ must be nonpolar/ can be polar or nonpolar depending on geometric configuration/ indeterminate. immediately

must be nonpolar

Explanation:

A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms. It is also defined as the bond which is formed due to the unequal sharing of electrons between the atoms.  Example:

Non-polar covalent bond is defined as the bond which is formed when there is no difference of electronegativities between the atoms. It is also defined as the bond which is formed due to the equal sharing of electrons between the atoms.  example:

Thus as , , molecules are formed by similar atoms with no electronegativity difference, the bond must be non polar.

Hence, the correct answer is the molecules   , , must be non polar.

increased stability in the completion of fluorine's outer shell.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
