You are probably referring to neutrons which are often found within the nucleus of an atom in numbers different from the protons. An atom of the element carbon, for instance, normally consists of 12 protons, 12 electrons and 12 neutrons. However, an isotope of carbon known as C13 consists of 12 protons, 12 electrons and 13 neutrons.

If the number of protons changes, the atom becomes an entirely different element. Changing the number of neutrons creates isotopes of the same element, which can have different properties. Changing the number of electrons alters the atom's charge, turning it into an ion.
Neutrons
The element that an atom is is determined by the number of protons. The number of electrons can be changed (creating an ion), and the number of neutrons can be changed (creating an isotope), and as long as the number of protons does not change, the element that the atom is does not change.
Changing the number of neutrons in an atom does not change the element it belongs to because the element is determined by the number of protons in the nucleus. Changing the number of neutrons would result in an isotope of the same element, not a new element.
Changing the number of neutrons in an atom affects its isotope but does not change its fundamental chemical identity. An element is defined by the number of protons in its nucleus (its atomic number), while isotopes have varying numbers of neutrons. Thus, changing the number of neutrons does not create a new element.
The number of protons in the nucleus of an atom determines the element. The number of neutrons can vary. If two atoms of the same element have a different number of neutrons in their nuclei, they are isotopes of that element.
Neutrons do not always equal the number of protons in an atom when there are isotopes present. Isotopes are atoms of the same element with different numbers of neutrons. This affects the atomic mass of the atom without changing its chemical properties.
The number of neutrons in one atom can vary depending on the element. Neutrons are one of the three main subatomic particles found in an atom, along with protons and electrons. The number of neutrons in an atom is calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom.
The number of neutrons in an atom can affect the atomic mass of an atom.
