B and C have the same atomic numbers, which means they have the same number of protons, which is the defining part of an element.
Because it has more protons than electrons. Protons are positive so if there is more of them than electrons, the ion will have a positive charge.
Answer:
N-1
Explanation:
All nitrogen positions in purine rings (N-1, N-3, N-7 and N-9) have the potential to form hydrogen bonds. Among them, only N-1 is involved in Watson-Crick base pairing hydrogen bond with a pyridimine. N-3 and N-7 are available to form further hydrogen bonds and N-9 is involved in a N-glycosyl linkage with a desoxyribose.
Answer:
N with a charge of (-3) is nitride
Explanation:
