The atomic number is the number of protons in the nucleus of the atoms of a given number. The elements are arranged in increasing order of atomic number on the Periodic Table.
In a neutral atom, the number of electrons is equal to the number of protons, however, the number of electrons is not the atomic number of an element.
The atomic number corresponds to the number of protons in an atom's nucleus. It uniquely identifies an element and determines its position on the periodic table.

What does the atomic number equal of an element?
The atomic number of an element is the number of protons in the nucleus of an atom of that element. It is a unique identifier for each element on the periodic table.
What is the atomic number of f plus the atomic number of Na equals the atomic number of this element?
The atomic number of F (fluorine) is 9 and the atomic number of Na (sodium) is 11. Adding them together gives 20, which is the atomic number of calcium (Ca).
The sum of the protons and neutrons in an atom equals the .?
atomic number
Whats a type of number that equals the amount of protons inside a nucleus and electrons outside a nucleus?
Atomic number represents the number of protons in the nucleus of an atom, which also equals the number of electrons outside the nucleus.
What describes an atomic number?
The atomic number is the number of protons found in the nucleus of an atom. It determines the element's identity and its place on the periodic table.
Who made atomic numbers?
M.GMosly found the atomic number. Atomic number is equals to protons.
What is the atomic number of F plus the atomic number of An equals the atomic number of this elements?
There is no element whose symbol is An.
The atomic number of an element equals the number of what atomic particles?
Atomic number = number of protons = number of electrons (in the neutral state)
What the atomic number of F plus the atomic number of Na equals equals the atomic number of this element?
The atomic number of F is 9, the atomic number of Na is 11. Adding them together gives a sum of 20, which corresponds to the atomic number of Calcium (Ca).
The number of protons equals the atomic number?
Yes.

What is hydrogen's number of neutrons equals mass number - atomic number equals?
The number of neutrons in an atom can be calculated by subtracting the atomic number (number of protons) from the mass number. For hydrogen, the atomic number is 1 and the mass number is also 1. Therefore, the number of neutrons in hydrogen is 1 (mass number - atomic number = 1 - 1 = 0 neutrons).
When you subtract the atomic number from the atomic mass it will give you the number of what?
the protrons, neutrons and electrons in a atom
How do you calculated electrons?
electron equals the atomic number
Mass number - atomic number equals?
Mass number minus the atomic number equals the number of neutrons. Mass number is the number of particles in an atom that have significant mass. Electrons are assigned a value of 0 since the mass is so much smaller than protons and neutrons. Protons and neutrons are similar in mass and are assigned mass number of 1. The formula for calculating atomic mass atomic mass = # protons + # neutrons.
How do the mass number and the atomic number of an element different?
Atomic number equals the number of protons, the (atomic) mass number equals the sum of (the number of) protons and neutrons of the same element.The answer is: they're differing in the number of neutrons(Mathematically: Where A = p and M = p + n, the difference in A and M is n)
