the atomic number is determined by the number of protons in a nucleus.
Number of protons or the atomic number of an atom determines what is the element.
The atomic number of an element can be used to determine the number of electrons in an atom. It is equal to the number of protons in the nucleus of an atom, which also corresponds to the number of electrons in a neutral atom.
The numbers of protons and of electrons in an atom are both the same as the atomic number, and the difference between the mass number and the atomic number is the number of neutrons in the atom.
The identity of the element is determined solely by the atomic number, which is the number of protons.
Atomic mass minus atomic number. This is rather simplified but the atomic mass of an element is the total of all the protons, neutrons, and electrons in an atom. Each proton and neutron has an atomic mass of approximately 1 AMU (atomic mass units) while an electron has an atomic mass of about 0.0005 AMU. So, you don't need to worry about the electrons. The atomic number of an element is simply the number of protons in the atom. So, atomic mass (number of protons and neutrons) minus atomic number (number of protons) equals number of neutrons in an atom.
The atomic number of any atom is determined by the number of protons in the nucleus of the atom.
atomic number
The number of protons
To determine the number of protons, look at the atomic number. The number of electrons is also the atomic number.To find the number of neutrons subtract the atomic number from the Atomic Mass number.
yes...
The number of electrons in an atom can be determined by looking at the atomic number of the element on the periodic table. The atomic number represents the number of protons in the nucleus of an atom, which is equal to the number of electrons in a neutral atom.
Number of protons or the atomic number of an atom determines what is the element.
The number of protons in the nucleus of an atom determines the atomic number of the element to which the atom belongs.
balk people always when
the number of electrons of an atom is the same as it's atomic number
Number of Neutrons = Mass number - Atomic Number
The number of neutrons in an atom determines the isotope of the element. Isotopes of an element have the same number of protons but differing numbers of neutrons. This affects the stability and nuclear properties of the atom.
