Atomic number = number of protons
Atomic Mass number = number of protons + number of neutrons
Relative mass number = the weighted average mass numbers of the naturally occurring isotopes as compared to C-12
If you delete the atomic number from the mass number you get the number of neutrons. The atomic number is the number of protons and electrons. (They are both the same number.)
Atomic radius decreases along the rows of the Periodic Table. Atomic radius increases along the columns. If you would care to examine the page given by the link you will find a graph showing the relationship that interests you as well as two copies of the periodic table representing atomic radii obtained in two ways respectively.
As the atomic number goes up, you have atoms with more particles of all three sorts (protons, neutrons, and electrons) which therefore become progressively larger, but not in a precisely defined way that can be expressed by a formula. They just get bigger.
Atomic radii ( diameter ) of group elements in general increase as increase of atomic number or as agroup is descended because electrons are being added to shells farther from the nucleus. So atomic radii order : Mg < Ca < Sr < Ba atomic number : 12 < 20 < 38 < 56 ...As I know there is no link or relationship between atomic radii sets and atomic numbers.
There is no exact general numerical relationship between atomic number and atomic mass, except that the atomic mass must be at least as large as the atomic number. The atomic number is always an exact integer equal to the number of protons in the nucleus of each atom of the element, and the atomic mass number of a single isotope of the element is always equal to the sum of the numbers of protons and neutrons in the nucleus of each atom of that isotope of the element. The atomic masses of an element, however, are generally not exact integers, for two reasons: The actual mass, in atomic mass units, of isolated neutrons is slightly larger than the actual mass of isolated protons, and both of these particles have actual masses in isolation that are slightly greater than the integer 1; and the rest mass of both protons and neutrons when collected into actual atoms can be different from the product of the number of each type of particle in isolation multiplied by the number of particles of that type in the nucleus as a result of nuclear binding energy quantum mechanical interactions.
The relationship between atomic number atomic radius in inversely proportional. The atomic number will increase as the atomic radius decreases.
The atomic radius decrease from left to right in a period.
The atomic radius increase from the top to down in a group.

Simply, the atomic number and the number of protons are the same. If the atomic number is 8, then there are 8 protons in the element.
Atomic number is the number of protons in the nucleus of an atom. All of the atoms of the same element have the same number of protons, and therefore the same atomic number. For example, all hydrogen atoms have one proton in their nuclei, and hydrogen's atomic number is 1; and all carbon atoms have six protons in their nuclei, and carbon's atomic number is 6. Each element's identity is determined by its atomic number. The relationship between the periodic table and atomic number is that the elements are arranged in the periodic table according to increasing atomic number, starting with hydrogen and ending with Ununoctium, which has an atomic number of 118.
The number of protons.
The atomic number of the element is the number of protons or number of electrons in an atom of the element . The atomic weight of the element is the ratio of the mass of the atom to the 1/12th of the mass of the atom of carbon 12.
The atomic number of an element equals the number of protons in the element.
The atomic number is the number of protons the element possesses.
The atomic number of a chemical element is identical to the number of protons.
Simply, the atomic number and the number of protons are the same. If the atomic number is 8, then there are 8 protons in the element.
The atomic number and number of protons are always the same in a normal element.
Proton number, which is an element's atomic number, identifies an element. Each element has a unique atomic number (number of protons).
Atomic number: number of protons in a nucleus unique to an element Atomic Mass number: number of protons + number of neutrons in a nucleus. May be a small range of values for a given element. Very roughly the atomic mass number is double the atomic number. For large elements it is more than double.

Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number. Mass number is the number of protons and neutrons in the nuclei of the atoms of a specific isotope of an element.
Atomic mass is the mass of 1 mole of the element. Atomic number is the number of protons the element has
The number of protons is the atomic number.
sodium chloride is a salt, a type of compound, not an element. it has no atomic number.
the atomic number is the number of protons in a certain element. elements are arranged on the periodic table by atomic number in increasing order
