Has only 7 electrons so it want to bond with other elements so its very reactive and unstable. Hope this helps
The difference between all three Magnesium, Mg isotopes is in; the number of neutrons.
<h3>What is
isotopy?</h3>
Isotopy is a property of elements in which case the element has two or more types of atoms that have the same atomic number and hence, same position in the periodic table, but differ in nucleon numbers due to different numbers of neutrons in their nuclei.
- Ultimately, the distinctive feature between the three isotopes is in their number of neutrons

Answer:
The answer to your question is (C). I would work out the question for you lad, but I don't know how to do it on here.
Explanation:
Helium has an atomic number 2 and an atomic weight of 4 grams per mole. It is one of the noble gas (which means that it is stable) and also a nonmetal. Its electron configuration is 1s2. There are energy levels and they are s, p, d and f. The s level means that its maximum number of electrons is only 2.
