No. the atomic number tells you the number of protons it has.
The ones that are elements. Since you didn't provide "the following," that's about the best we can do. This is an absurdly simple question for you to answer yourself anyway. Find a periodic table, look at it, look at the list.
It is important so you can knoe the atoms number of protons, nuetrons, and electrons. You can also know it's atomic weight, physical property, and state of matter.
Pretty much any element is identified by its atomic number or number of protons; in the case of beryllium it has four of them in its nucleus. It's somewhat a matter of convention that it is beryllium by definition so long as it has those four protons; any element might be in a different oxidation state having gained or lost electrons, or be a different isotope by varying the number of neutrons, but the atomic number or number of protons is used to identify elements.
Promethium is a chemical element with the symbol Pm and an atomic number of 61. It is solid at room temperature.
The atomic number of a chemical element is equivalent to the number of protons and electrons, in the neutral state.
Examples: atomic number, atomic weight, density, state of matter, electrical conductivity, etc.
Elements in the table are identified by different things. What they are made of, atomic mass, and atomic number. Elements can also be identified by what state of matter they are at zero degrees Celsius and standard pressure which 1atm. The most current, standard table has 117 different elements.
Literal groups are by similar chemical properties (alkaline earth, halogens, etc.). Elements are arranged by atomic number (number of protons) and are grouped also by their state of matter. For example, metals are in the middle, liquids are grouped together, and except for Helium, gases are as well.
Their atomic number, which represent the number of protons in the nucleus. This will also be the number of electrons in the unionised state of the atom.
No two elements would have the same atomic number, so, nor atoms of different elements (in neutral state) would have the same number of electrons.
The matter for most elements is a solid.

There are many elements among the transitional elements which has the electron configuration differed than predicted. Such element with the lowest atomic number is chromium.
Atomic number = number of protons = number of electrons (in the neutral state)
It is important so you can knoe the atoms number of protons, nuetrons, and electrons. You can also know it's atomic weight, physical property, and state of matter.
An elements atomic number is important because it tells you how many protons are in the nucleus of the atom, and how many electrons are orbiting the nucleus in the ground state.
