There are three elemental forms of carbon (C). Carbon can be in the form of what is misnamed pencil lead. The hardest and most rigid structure on Earth is diamond, which is also pure C. Carbon forms the basis for coal also.
if it is a netrual atom it will have 3 but if it is charged it will change
An atom is the basic unit of matter consisting of a nucleus (protons and neutrons) surrounded by electrons. Two examples of atoms are hydrogen, which has one proton and one electron, and oxygen, which has eight protons, eight neutrons, and eight electrons.
Mass number is the total number of protons and neutrons in an atom's nucleus. Non-examples of mass number would include atomic number (number of protons in an atom), electron configuration (arrangement of electrons in an atom), and atomic mass (average mass of an atom, taking into account all isotopes).
An atom of lithium isotope 6Li has 3 electrons and 3 protons and 3 neutrons.
The oxidation number of the central atom Al in AlF6^3- is +3. This is because each F atom contributes a -1 charge, and the overall charge of the complex ion is -3, so the Al atom must have a +3 oxidation state to balance it out.
There are many examples of atom, 106 in fact. Look at the Periodic Table of the elements.
Gold
Molecules are not atoms, so I assume they can be classified as non-examples of atoms. Water is a molecule, and therefore not an atom. Water is comprised of two hydrogen atoms and one oxygen atom. Carbon is an atom.

Sodium, Aluminium, Chlorine gas....every thing that are in its element form or only consist of one type of atom is called element.
An atom is the smallest unit of an element that still maintains the physical properties of the element. Examples are: hydrogen, oxygen, gold, aluminum, neon, silver, carbon, potassium.
A model of the atom is a 3-D structure of the atom's structure.
It is called a polyatomic anion. Some examples are phosphate (PO4^3-), sulfate (SO4^2-), nitrate (NO3^-).
An atom is the basic unit of matter consisting of a nucleus (protons and neutrons) surrounded by electrons. Two examples of atoms are hydrogen, which has one proton and one electron, and oxygen, which has eight protons, eight neutrons, and eight electrons.
Based on the atomic number of lithium there are three protons in a lithium atom.
Mass number is the total number of protons and neutrons in an atom's nucleus.
