The atomic number of an element is determined by the number of protons in the nucleus of its atom. It is a unique identifier for each element on the Periodic Table. The atomic number also determines an element's position in the periodic table and its chemical properties.

The number of neutrons in the nucleus of an atom can be calculated by what?
The number of neutrons in the nucleus of an atom can be calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom. Atomic mass - Atomic number = Number of neutrons.
Cesium-133 has an atomic number of 55 It has neutrons?
Cesium-133 has an atomic number of 55, which means it has 55 protons in its nucleus. Since the atomic number represents the number of protons, the number of neutrons in an atom of cesium-133 can be calculated by subtracting the atomic number from the atomic mass.
How can the number of protons electrons and neutrons be calculated when giving the mass number?
To calculate the number of protons, electrons, and neutrons based on the mass number: The number of protons is equal to the atomic number of the element. The number of electrons is also equal to the number of protons in a neutral atom. The number of neutrons can be calculated by subtracting the number of protons (atomic number) from the mass number.
What is the number of neutrons in argon?
The number of neutrons in an argon atom is 22. This is calculated by subtracting the atomic number of argon (18) from its atomic mass number (40).
Atomic mass and number of fluorine?
The atomic number of fluorine is 9, which means it has 9 protons in its nucleus. The atomic mass of fluorine is approximately 19. It is calculated by adding up the number of protons and neutrons in its nucleus.
How Mendeleev calculated atomic number in 17 th century?
Mendeleev calculated atomic number by increasing atomic number, which match the number of protons in an atomic nucleus of a single element
What does the formula atomic mass minus the atomic number equal?
By subtracting the mass number and the atomic number, the number of neutrons can be calculated.
How is the number of neutrons in an atom found?
The number of neutrons in an atom can be found by subtracting the number of protons (which is the atomic number) from the mass number. The mass number is the sum of protons and neutrons in the nucleus of an atom.
How do you calculated electrons?
electron equals the atomic number
Can the number of neutrons in the nucleus be calculated by subtracting the atomic number from the mass number?
Yes.
How is the atomic mass calculated for neon?
Neon is a non meta element. Atomic mass of it is 20. Atomic number of it is 10.
Neutrons in the nucleus of an atom calculated?
Mass number minus atomic number = number of neutrons
What is equal to the total number of protons and neutrons?
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
Protons are the same as the mass or the atomic?
The atomic number is the number of protons. For example, the atomic number of Hydrogen is 1, because it has 1 proton. The mass is calculated using protons, neutrons, and electrons.
How can the number of protons electrons and neutrons be calculated when giving the mass number?
To calculate the number of protons, electrons, and neutrons based on the mass number: The number of protons is equal to the atomic number of the element. The number of electrons is also equal to the number of protons in a neutral atom. The number of neutrons can be calculated by subtracting the number of protons (atomic number) from the mass number.
How do you calculate nutrons?
neutron can be calculated by subtracting the atomic number of the particular atom from its mass number.
How is atomic mass mass number and atomic number calculated?
Allthese can NOT be calculated being physical properties of each specific element. They can be found in 'periodic tables' eg. by typing in the element name in a wikipedia-search
