It is the number equal to the number of protons in the nucleus of an atom.
the number of electron or proton present in anyatom is called "atomic number/Charge number" of that atom it is denoted by Z.
For Example.
atomic number of Na is 11. Atomic number of Ca is20

The atomic number of an atom is also equal to which quantity?
Firstly, an atom is uncharged by definition. If it is charged, that is it has gained or lost electrons, its name is changed to an ion. The atomic number is the number of protons of an atom of that element. And the number of protons is equal to the number of electrons.
What is the number of protons for Florine?
Fluorine has 9 protons per atom: The number of protons per atom is by definition the atomic number of an element, and reference to a periodic table shows that the atomic number of fluorine is 9.
What is the AMU of carbon?
AMU stands for atomic mass units; the number of units an element has is called its atomic mass. The atomic mass of carbon is exactly 12, by definition.

This element has the atomic number that is double the atomic number of silicon?
The element with an atomic number that is double the atomic number of silicon is germanium, with an atomic number of 32. Silicon has an atomic number of 14.
What is the atomic number for fluorine17?
The atomic number for any isotope of fluorine is always 9; that is the "definition" of fluorine.
What is the atomic definition?
Atomicity is having atoms. Also the number of atoms in a molecule.
How many protons does an atom with an atomic number of 34 and a mass number of 79 have?
The number of protons in an atom of any atomic number is the same as the atomic number, because that is the definition of atomic number. Therefore, in the given question, the answer is 34; the mass number is not needed to answer.
Term for an atom that has the same atomic number as another atom but differs in atomic weight?
This is the definition of an "isotope".
How is the atomic number of an element related to the protons in an element?
Identically the same, by definition.
What is the number of protons for an element is the same as the number of the subatomic number?
By definition, the number of protons in the atoms of an element is the atomic number of the element.
How do you know which element have the greatest number of protons in their nucleus?
The elements with the highest atomic numbers have the greatest numbers of protons in their nucleus, because that is the definition of atomic number.
Why would an elements atomic number change after transmutation?
Transmutation by definition means the conversion of one element into another, and so it follows that its atomic number must also change. Every element has a unique atomic number.
How many protons does atomic number of 15?
The atomic number is the number of protons, so 15.
What is the Proton number for florine?
Fluorine has 9 protons per atom: The number of protons per atom is by definition the atomic number of an element, and reference to a Periodic Table shows that the atomic number of fluorine is 9.
