We use atomic number for recognize chemical elements. atomic number means, how many protons are there in a single 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
The atomic number of an atom is the number of protons in its nucleus. It determines the element's identity on the periodic table and is used to arrange elements in ascending order based on their properties.
The atomic number is equal to the number of protons and neutrons in a neutral atom.
The atomic number of an atom is determined by the number of protons it has.
Atomic number is the number of protons in the nuclei of the atoms of an element. It is the number of protons that determines the atomic number. In a neutral atom, the number of electrons equals the number of protons. So in a way you could say that atomic number determines the number of electrons in a neutral atom.
The atomic number of an atom is the number of protons in its nucleus.
The atomic number of an atom is the number of protons in its nucleus.
Atomic number is the number of protons in a neutral atom
The atomic number of an atom is equivalent to the number of protons in its nucleus.
An atom's atomic number is the number of protons within the single atom of an element
The number of protons is the atomic number.
The atomic number of an atom is the number of protons in that atom. For example, the atomic number of hydrogen is 1 because one hydrogen atom have one proton.
