Neurons are nerve cells in the body but if you meant neutrons nothing normally happens; it sometimes increases radioactivity.
Transmutation always involves a change in the number of protons in the atom, which changes the atomic number and the element of the atom. It also involves at least some slight change in the mass of the atom (but not necessarily the mass number, which is the number of protons plus the number of neutrons, and not the same as the actual mass).
In the nucleus of the atoms of the elements concerned
It is very unusual for one kind of atom to become another kind atom, however it does happen in radioactive processes. Every element is characterized by a distinct number of protons. For example, all hydrogen atoms have 1 proton, all helium atoms have 2 protons, etc. Atoms also include electrons and neutrons. However, adding or removing electrons or neutrons does not change the kind of atom. For example, a helium atom with 2 electrons or 1 electron is still a helium atom. Alpha decay is an example of a radioactive process in which the number of protons changes (and therefore the kind of atom changes). An alpha particle includes 2 protons and 2 neutrons. When it is expelled from an atom, a new kind atom is formed. This occurs when a uranium atom (92 protons) is changed into a thorium atom (90 protons) + an alpha particle.
The nucleus of the atom doesn't have a negative charge. It has protons with a positive charge and neurons that don't have a charge.
The number of neutrons in an atom can affect the atomic mass of an atom.
no. because if the number of protons changes, then the element changes
The particle in an atom that cannot change is the number of protons. If that changes, it is no longer the same element.
the number of protons determine what the substance is. if the number of protons in an atom change, the substance made of that atom changes too.
The number of neurons in an atom is independent to the number of protons.
The protons don't change because if the number of protons changes, the type of element the atom is changes. The number of protons determine the species of the atom.
a charged particle if the atom is neutral before the change
The type of atom is now different from what it was. (It has a new identity.)
Transmutation always involves a change in the number of protons in the atom, which changes the atomic number and the element of the atom. It also involves at least some slight change in the mass of the atom (but not necessarily the mass number, which is the number of protons plus the number of neutrons, and not the same as the actual mass).
neutrons
Nothing happens to the number of neutrons nor protons. it's just the electron number that changes. If an atom gains electrons, it increases and the ion is negative and vice versa. the number of neutrons or protons DOES NOT CHANGE.
the atomic number never changes
By changing the number of neuturons the atom is converted into isotope. As we know the atom is made up of electrons(negative charge),protons(positive charge) and neutrons(no charge),when we change number of electrons in an atom ions are created in the same way change in number of protons create change in the identity of atom and change in neutrons results isotopes
