This was an answer i found on google from Nasa
Covalent
bonds = sharing of electrons between two atoms of the same elements or elements
close to each other on the periodic table. Usually they are metals sometimes
non-metals. In polar bonds electrons are
shared unequally. Non polar bonds share electrons equally.
Answer:
The octet rule is a chemical rule of thumb that reflects the observation that main group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas
Explanation:
1 mole is 6.02x 10^23 molecules
3 * 6.02*10^23 =1.806*10^24 molecules
