7. Nitrogen has two naturally occurring isotopes: nitrogen -14 (99.632%; isotopic mass=14.003074 amu) and nitrogen -15 (0.31 %; isotopic mass = 15.00010 amu). Calculate the atomic weight of nitrogen

i think slash and

it takes on an electronical energy

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
