The mass number of an isotope of an element is defined as the sum of the numbers of protons and neutrons in the nucleus of each atom of the isotope. The atomic number is defined as the number of protons only in the nucleus. Therefore, an atom with an atomic number of 6 has 6 protons in its nucleus.
Atomic number means number of protons present in an atom. Atomic number= number of protons. mass number = number of neutrons+ number of protons. So if you subtract the number of protons you get neutrons and if you subtract neutrons you get protons. mass number - protons= neutrons Mass number - neutrons = protons.
ruthenium has a atomic number of 44 and a mass of 101. how many protons does ruthenium have?
Mass is irrelevant when determining the number of PROTONS. The atomic number is the number of PROTONS so the answer is 19. Mass is approximately number of PROTONS plus the number of NEUTRONS. ELECTRONS mass is so small compared to protons and neutrons that they are usually ignored.
Number protons + number neutrons is called the mass number or the atomic mass.
Atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom the number of neutrons would equal the mass number minus the atomic number.
No it is not the atomic number. We call it mass number.
The nucleus of an atom consists of protons and neutrons. The number of protons in a particular nucleus is its "atomic number". The total number of protons and neutrons in a particular nucleus is its "mass number".
Atomic number means number of protons present in an atom. Atomic number= number of protons. mass number = number of neutrons+ number of protons. So if you subtract the number of protons you get neutrons and if you subtract neutrons you get protons. mass number - protons= neutrons Mass number - neutrons = protons.
Find out how many protons (atomic number) and what the mass number of a particular element is. Then subtract the number of protons from the rounded mass number to get the number of neutrons in a particular atom.
Atomic Mass: protons AND neutrons atomic number: just protons
atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number
The atomic mass number tells how many protons and neutrons are in a nucleus.
Atomic mass is determined by the number of protons and neutrons in an atom's nucleus.
The Atomic Number of an element is equal to the number of Protons/Electrons in the nucleus and the Atomic Weight is approximately the total number of Protons/Electrons and Neutrons combined. Using Carbon as an example: Total Protons/Electrons = 6, therefore the Atomic Number is 6 Total Neutrons = 6, and the Atomic Weight is 12 Question? The Atomic Number of Lithium = 3 The Atomic Weight of Lithium = 7 How many Protons/Electrons? How many Neutrons? Answer: Protons/Electrons = 3 Neutrons = 4
Close; Mass # is the number of protons + the number of neutrons.
The Atomic Number is the number of protons. The Atomic Mass Number is the number of protons plus the number of neutrons of a particular isotope.neutrons and protons
atomic mass number - protons = number or neutrons
