Protons and neutrons are particles that make up the dense nucleus at the center of an atom. Protons have a positive electric charge, and neutrons have no electric charge (i.e., neutrons are electrically neutral).
Electrons are particles that are found surrounding the nucleus; electrons have a negative electric charge.
The magnitude of a proton's positive charge and an electron's negative charge are equal in magnitude. All they differ in is in their polarity.
So, an atom that has the same number of protons and electrons would be electrically neutral. An ion is an atom that has a non-neutral charge because of an imbalance between the number of protons and electrons. If there are more electrons than protons, there is a net negative charge, and this type of ion is called an anion; if there are fewer electrons than protons, there is a net positive charge, and this type of ion is called a cation.
In this case, we have an element (or, more precisely, an atom of an element) that has 35 protons, 36 electrons, and 45 neutrons. There is one more electron than there are protons. This is called an anion because there are fewer electrons compared to protons.
Considering the definition of ion, cation and anion, this is called an anion because there are more electrons compared to protons.
All atoms are composed of a central nucleus in which there are particles with a positive electric charge, the protons, around which other particles with a negative electric charge that are electrons move. Thus, the atom is electrically neutral, since the positive charge of the protons is compensated by the negative charge of the electrons.
On the other hand, an ion is a particle with an electrical charge obtained by adding or removing electrons from atoms or molecules.
An electron-deficient atom or molecule has a positive charge and is called a cation; On the other hand, when there are excess electrons, the ion has a negative charge and is called an anion.
In other words, if an atom, or atoms, does not have a balanced number of negatively charged electrons and positively charged protons, these species will be charged and are called ions.
A cation has more protons than electrons, giving it a net positive charge. For a cation to form, one or more electrons must be lost.
An anion has more electrons than protons, which gives it a net negative charge. For an anion to form, one or more electrons must be gained.
In this case, an element has 35 protons, 36 electrons, and 45 neutrons. This is called an anion because there are more electrons compared to protons.
