The atomic number is the number of protons in an atom. In an electrostatically neutral atom, ie not an ion, it is also the number of electrons. Every single atom of an element will have the same number of protons, eg. Carbon always has six protons. This also helps us to understand the layout of the electron in an atom. Carbon has six so it arranges them into an inner group of two and an outer group of four, meaning it can have up to four bonds. Hope this helps.

What is the atomic number a measure of?
The atomic number is a measure of the number of protons in an atom's nucleus. It determines the element's identity on the periodic table.
How is the mass number of an isotope different from the average atomic mass that is on the periodic table?
The mass number for a particular isotope of an element is a precise value. The average atomic mass for an element is the value you would measure for that element given all the isotopes it has and their abundance in the sample.
What is the atomic number of the element with the symbol Be?
The atomic number of the element with the symbol Be (Beryllium) is 4.
What is the element of a atomic number element?
The atomic number of an Element refers to it's position in The Periodic Table. The first element (Hydrogen - H) has the atomic number 1. The second element (Helium - He) has the atomic number 2. The fifty-second element (Tellurium - Te) has the atomic number 52. And so on.

What does the atomic mass of an element measure?
Atomic mass of an element measures the mass of that element on a molecular scale, taking into account neutrons and protons, which weigh approximately 1. Electrons are negated. Atomic mass is also the mass, in grams, of 1 mole of that element.
Define atomic radii?
The atomic radii is the measure of the size of the atoms in a chemical element. This is the distance from the nucleus to the boundary of the electrons' cloud.
When does atomic number occur?
It doesn't occur its just the way an way they measure atoms in an element

What is the weight of the mole?
The weight of a mole depends on the substance you are measuring. The formula is as follows 6.022e23 (Avogadro's number) multiplied by the atomic weight of the element you wish to measure. You can find the atomic weight for any element on the periodic table of elements.
