the smallest component of an element having thechemical properties of the element, consisting of anucleus containing combinations of neutrons and protons and one or more electrons bound to the nucleusby electrical attraction; the number of protonsdetermines the identity of the element.
an atom with one of the electrons replaced by someother particle: muonic atom; kaonic atom.
In chemistry, the term "valence" refers to the combining capacity of an atom, which is determined by the number of electrons it can gain, lose, or share in order to achieve a stable electron configuration.
In chemistry, an ion is an atom or molecule that has gained or lost one or more electrons, resulting in a positive or negative charge.
Linus Pauling defined electronegativity as "the ability of an atom in a molecule to attract electrons to itself."
Atom is the word used to describe a single unit of an element by all professional scientists. That is the only word you should use.
In chemistry, the term nucleus generally refers to the central part of an atom that contains the protons and neutrons. It is also used to describe the central part of a cell where genetic material is housed.
One or more of the same Atom.

The term atom comes from ancient Greek meaning indivisible.
An atom smasher is an informal term for a particle accelerator.
The atomic number represents the number of protons in an atom's nucleus, determining the element's identity. The mass number is the sum of the protons and neutrons in an atom's nucleus, giving the atom its mass.
"Atom" in Greek is "άτομο" (átomo), which translates to "indivisible" or "uncuttable." This term was used by ancient philosophers to describe the smallest unit of matter that could not be divided further.
When an atom has an electric charge it is called an ion.
In chemistry, the term "valence" refers to the combining capacity of an atom, which is determined by the number of electrons it can gain, lose, or share in order to achieve a stable electron configuration.
