What is atomic number equal to?
atomic number, the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus. Accordingly, the number of protons, which is always equal to the number of electrons in the neutral atom, is also the atomic number.

How do we calculate atomic mass?
Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
Why atomic number is unique?
The atomic number (Z) of an element is the number of protons in the nucleus of each atom of that element. This means that the number of protons is the characteristic which makes each element unique compared to all other elements.

Why can’t you see an atom with the naked eye?
An atom cannot be visible to the naked eyes because, Atoms are miniscule in nature, measured in nanometres. Except for atoms of noble gasses, they do not exist independently.
What is atomic number class 9th?
The atomic number of an atom is equal to the number of protons in the nucleus of an atom or the number of electrons in an electrically neutral atom. Atomic number = Number of protons. For example, in a sodium atom, there are 11 electrons and 11 protons.
Is atomic mass and mass number same?
The mass number is the sum of the number of protons and neutrons in an atom. It is a whole number. The atomic mass is the average number of protons and neutrons for all natural isotopes of an element.
