Protons
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"
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.
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 number
the answer is that it is called a atomic number.
It is called the atomic no. of element. It is also equal to the no. of electrons in the atom.
Atomic number
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.
Atomic number of an atom shows the number of protons in the nucleus of the atom. OR Atomic number of an atom is the number of electrons in the atom when the atom neutrally charged
atomic number
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.
