It is the number of protons in the nucleus of an atom. It defines what element the atom is.
The atomic number is the number of protons in an atom, and each element has a unique atomic number. This means that the atomic number is used to identify and distinguish one element from another. The number of protons in an atom determines its chemical properties and its placement on the periodic table.
The atomic number is equal to the number of protons in the atomic nucleus. It is an individual characteristic.
Each element has its own specific atom number because that's what they differ in: the number of protons (from 1 up to over 100)
Atomic numbers represent the number of protons in an atom's nucleus. It also defines the element, as each element has a unique atomic number.
Protons distinguish one lement from another because the number of protons in an element is equal to the atomic number, and each element has its own atomic number for example Hydrogen's atomic number is 1, which means it has 1 proton
The unique number of protons in the nucleus of an atom is an element's atomic number. This identifies an element.
The unique number of protons in the nucleus of an atom is an element's atomic number. This identifies an element.

Every element has a different number of protons and electrons in each atom, and this amount is what the atomic number tells you.
There is no element with the atomic number 3.14. Atomic numbers are whole numbers that represent the number of protons in an atom's nucleus.
Actually atomic number is the number of protons or number of electron's a neutral atom ,both are equaling the atom loses the electron it becomes charged. For example's case of hydrogen the atomic number is in case of helium the number is 2.helium is inert because is shell is completely filled. Same with the case of all inert gasses in case of atomic instability the atom radiates the ray sand other particle's a result ,the atomic number varies and hence the atom turns to be the atom of other element. I hope this will be convincing.
The number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table
The atomic number indicates the number of protons in an atom's nucleus, which determines its identity as an element. It is crucial because it helps to distinguish one element from another on the periodic table and influences the atom's chemical properties.
Each element has its own specific atom number because that's what they differ in: the number of protons (from 1 up to over 100)
