The atomic number of an element is equal to the number of protons in the nucleus of that element; it will identify the element. The number of neutrons of a given element may be different as the element may have a number of isotopes.
The smallest particle that has characteristics of that element is the atom. The atom is made up of a certain amount of protons, electrons and (neutrons) and those are what give the characteristics of that element to that atom.
This is the atomic number (equal to number of protons).

To identify an element, you can refer to the Periodic Table. Elemental analysis like combustion analysis is very common to know the composition of the sample.
Phosphorous is a chemical element that is always present in its oxidized state. It is never found as a free element. The primary source of phosphorous is in foods.
An atom is the smallest particle of an element that can be uniquely identified as that specific element.Note that this question is different from asking "What is the smallest particle in an atom?" (see related question below). Atoms are composed of smaller particles (protons, electrons, and neutrons), but the smallest thing that has the identity of a specific element is the atom.The smallest particle of an element that still retains all that element's properties is called an ATOM.
The most abundant element in any organic structure, including the human is hydrogen.
Atomic Mass
The elements are identified by atomic number. The atomic number is equal to the number of protons in each atom of the element. Of course the elements are usually identified their symbols, which are arbitrary.
yes
malleable
Yes you can recognize it. We use atomic number for that.
Yes. This is called an element's atomic number, and it is the key identifier for this element.
An atom is the smallest piece of an element that can be identified as that element.
Oxygen was first identified as an element in 1774 by English chemist, Joseph Priestley
An atom.

The number of protons.
The atomic number of an element refers to the number of protons in the nucleus within the element. This is how the element is identified.
