Do you mean "Why is the number of protons in an atom called the atoms atomic number?" The defining characteristic of an atom is the number of protons in its nucleus. Hydrogen has one proton. All atoms of hydrogen have one proton. Helium has two protons. If you add a proton to a hydrogen nucleus you get a helium nucleus. Since the number of protons defines what element the atom is, it is the defining characteristic.
What else can I help you with?
The protons in the nucleus of an atom is called the?
the no. of protons or the no.of electrons inthe nucleus ofan atom is called the atomic number of that atom.
What is the number of protons in the neucleus called?
the answer is that it is called a atomic number.
The number of protons in an atom of an element?
The number of protons in an atom of an element is its atomic number. It determines the element's identity and is unique for each element. The number of protons also defines the element's chemical properties.
What is the number of protons in an atom known as?
It is called the atomic no. of element. It is also equal to the no. of electrons in the atom.
Atomic number equals the number of?
The atomic number is equal to the number of protons in the nucleus and in a neutral atom will also equal the number of electrons.

The atomic number of an atom is equivalent to which of the following?
The atomic number of an atom is equivalent to the number of protons in its nucleus.
What you the relationship between the number of protons and the atomic number of an atom?
The number of protons is the atomic number.
How is called the number of protons in an atom?
In a neutral atom, the number of protons is equal to the number of electrons. Therefore it is also equal to the atomic number of the particular atom.
Is the sum of protron and neutrons of an atom is called the atomic number?
No, the sum of protons and neutrons in an atom is called the mass number, not the atomic number. The atomic number is the number of protons in an atom, which determines its chemical properties and its place on the periodic table.
The number of protons in the nucleus of an atom is called the what?
Atomic number
What is the atomic number of an atom determained by the number of what?
The atomic number of an atom is determined by the number of protons it has.
Number of protons in an atom is called?
The number of protons in an atom is the atomic number. It tells you which element the atom is.
