Atomic radius is the measure from the middle of an atom to the outter edge. Usually mesured between two atom. Measure from the middle of one atom to the middle of another and then divide by two.
is the atomic mass
ATOMIC MASS ;The total numbers of protons and neutrons present in the nucleus of an atom is called atomic mass and it is represented by A ATOMIC NUMBER;the number of protons in the nucleus of an atom are called atomic number or proton number and it is represented by Z
Atomic weight is a unit of measure whose unity value is that of the mass of a Hydrogen atom "1".

the no. of protons or the no.of electrons inthe nucleus ofan atom is called the atomic number of that atom.
the atom's "atomic number"
because it is from an atom. think about it atom-ic. not that hard of a concept
It is called the atomic no. of element. It is also equal to the no. of electrons in the atom.
Exactly the mass of an atom expressed in atomic units of mass (u).
Since the Earth is not a single atom, nor a collection of similar atoms, it does not have an atomic mass. Atomic mass is a measure of how much matter is contained by a specific atom.
Atomic mass
it is the branch of physics that deals with the structure and the behaviour of an atom is called atomic physics
the mass of an atom is concentrated in a very small central portion of the atom which is called the atomic nucleus. The atomic nucleus is made up of nucleons, of which there are two important fundamental types: electrically positive protons and electrically neutral neutrons. So the Answer for the question is: Neutrons and Protons.
It is equal to the no. of electrons in the atom. It is called the atomic number.
