A particle that contains 8 proton, 9 neutrons and 7 electrons could be written as?
O
O+
N
O-
Correct answer is B
The atomic number is the number of protons in the nucleus of an atom.
The number of protons define the identity of an element (i.e., an element with 8 protons is a carbon atom, no matter how many neutrons may be present).
If an atom loses or gains electrons, it will become a positively or negatively charged particle, called an ion.
The loss of one or more electrons results in more protons than electrons and an overall positively charged ion, called a cation.
