• All the above are right

the attraction that forms when atoms when they share electrons as knows as

• cavalent bond

• weird bond

• covalent bond

• normal bond

what is a nonpolar bond

• a bond between elements from group 6 and group 8

• a bond between two polar bears

• Atoms share electrons but act like they're not talking.

• Is covalent Bond in which electrons are shared equally by both atoms

polar as in polar bond means having ________ ends.

determine if this statement is true polar molecule means one in which the unequal sharing of electrons result in a slightly positive end and a slightly negative end although the overall molecule is neutral.

• True
• Partially true
• Maybe
• False

which of these is oxidation number.

• Lucky number

• positive or negative number
