Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of meitnerium is 109. Each isotope of an element has a different number of neutrons.
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
As electrons have such a small mass, they are not counted in the atomic mass. Thus the mass of an atom with 19 protons and 20 neutrons is 39.
A neutral atom with an atomic mass of 36 amu will have 36 electrons. This is because the atomic mass of an atom is determined by the sum of its protons and neutrons, and in a neutral atom, the number of electrons is equal to the number of protons.
atom have: 20 protons,20 electrons and20 neutrons ion have: 20 protons 18 electrons( metals lose electrons) and20 neutrons
Vanadium has an atomic no. of 23 and mass number of 51. But it has 28 neutrons and 23 electrons
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of meitnerium is 109. Each isotope of an element has a different number of neutrons.
Americium has 95 protons and electrons. Number of neutrons: Atomic Mass of an isotope - number of protons
Atomic mass is protons + neutrons, and the atomic number (4) gives you the number of protons. Thus, this atom would have 5 neutrons.
The number of protons (or electrons) an atom has. To find out how many neutrons there are take the atomic number and subtract it from the Atomic Mass... (atomic mass)-(atomic number)= neutrons atomic number= #of protons (or #of electrons)

The atomic number of a chemical element is equal to the number of electrons or protons. The number of neutrons = Atomic weight of an isotope (rounded) - atomic number of the element (or the number of protons)
a neon atom has 10 electrons , 10 protons , and 10 neutrons. its mass no. is 20 and atomic no. is 10. it is a stable atom.
Silicon-29 has 14 protons (atomic number), 14 electrons if the atom is neutral, and 15 neutrons (mass number - atomic number).
The isotope sulfur-46 has 16 protons and electrons and 30 neutrons (the exact atomic mass is 46.000750).
An atom of neon consists of 10 protons, 10 neutrons and 10 electrons (atomic number = 10; atomic mass = 20)
10 protons, 10 neutrons, 12 electrons
