An atom of one of the few elements that have only one radioactively stable isotope naturally occurring. Even this is not quite literally true, because all atoms have radioactively unstable isotopes that have different numbers of neutrons.
They are called isotopes,
An isotope
Neutrons have no significant effects on an atom's properties other than its mass. Nearly all chemical and physical properties of an element are determined by the configuration and number of electrons it has, which is in turn determined by the number of protons in the nucleus. As a result two atoms of the same element but with different numbers of neutrons (called isotopes) will behave identically.
The number of electrons and neutrons may differ for atoms of the same element. However, what distinguishes atoms of one element from those of a different element is the number of protons in the atom's nucleus. All of the atoms of an element have the same number of protons, which is the single most important determiner of the properties of an element.
An isotope of an atom has the same number of protons but a different number of neutrons compared to the common form of that atom. This results in isotopes having the same chemical properties but different atomic masses.

An atom of an element that differs in the number of neutrons compared with other atoms in the same element is called an isotope. Isotopes have the same number of protons and electrons but different numbers of neutrons, resulting in variations in atomic mass.
Atoms of all elements can have neutrons in them. Only the element hydrogen has an isotope whose atoms do not contain neutrons, but all other isotopes of hydrogen have neutrons in them. In the heavier elements the number of neutrons always exceeds the number of protons in the atom.
Isotopes of an element have the same number of protons but differing numbers of neutrons in the nucleus.
Neutral atoms of the same element can differ in the number of neutrons, which results in different isotopes of the same element. Isotopes have the same number of protons and electrons, but different numbers of neutrons.

No. All atoms of the same element have the same number of protons and, when neutral, the same number of electrons. They can, however, differ in the number of neutrons.
This atom is called isotope.
The atomic number for an element with 54 protons is 54. For the atoms with 77 neutrons, the mass number would be 54 (protons) + 77 (neutrons) = 131. For the atoms with 79 neutrons, the mass number would be 54 (protons) + 79 (neutrons) = 133.
No. Some may have different numbers of neutrons. Atoms of the same element (atoms with the same number of protons in the nucleus) may have different numbers of neutrons, and so will have different masses. As an example, chlorine is a mixture of different isotopes with some of the atoms having different neutrons numbers.
Isotopes are atoms of the same element with different numbers of neutrons. Mixtures, on the other hand, are combinations of different substances that are physically mixed together, but not chemically bonded.
