Carbon atom
A molecule is the smallest unit of a pure substance that can exist and still retain its chemical properties. An atom is the smallest unit of an element that can exist and still retain its chemical properties.
Yes, different isotopes of an atom retain the properties of the atom.
Isotopes of an atom does retain the properties of the atom. This is discrete in units of matter.

This smallest unit of matter is the atom.
No. The smallest particle of an element that has the properties of that element is an atom.
The addition of neutrons to the nucleus of an atom creates a new isotope of the element. It changes the nuclear properties of the atom, but has no effect on its chemical properties. Chemical reactions occur as the result of interactions between the electrons of atoms, not their nucleii so, for example, Carbon-12 and Carbon 14 will react chemically in exactly the same ways. The resulting compounds will have identical chemical properties but different molecular weights.
An Atom. An atom contains protons , neutrons and electrons. The number of protons in an atom gives it its characteristics. e.g. Hydrogen has ONE proton. Carbon has SIX protons. et seq/.
By definition, an atom of an element is the smallest particle of the element that retains its chemical properties. The answer is "an atom of carbon." A group of 6 protons. It could have 6 neutrons and 6 electrons, but it does not necessarily have to. It could have a different amount of neutrons and hence a different weight (an isotope), or a different number of electrons and be electrically charged (an ion). These are all still considered to be carbon atoms and chemically act as carbon.
Because the number of protons and electrons remain unchanged.
A carbon atom.
