Answer: " <span>1.8 * 10²⁴ molecules of O₂ " .
________________________________________</span>
3.0 moles O₂ * (6.02 * 10²³ molecules O₂ / 1 mol O₂) =
[ (3.0) *(6.02 * 10²³) ] molecules O₂
= 1.806 * 10²⁴ ; round to 2 significant figures.
= 1.8 * 10²⁴ molecules of O₂ .

<span>The main difference between carbon-12 and carbon-14 is the number of neutrons present in each compound. Carbon-12 has six neutrons, while carbon-14 has eight neutrons, explains About.com. The differing number of neutrons is responsible for numerous differences between the two compounds.</span>
The reason for this is because nonmetals, have close to fulfilling an octet and need to gain few more electrons to do this, not to lose more. Nonmetals, because of the fact they need only few more electrons to satisfy their octet they would receive or share electrons to do this.
The property that nonmetals have are that they are very electronegative, they possess a strong affinity to pull electron density closer, because they possess fewer electron shells and possess even protons this allows for this.
