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 the number of protons in the nucleus, which also determines the element's identity. The atomic mass is the total mass of an atom, which includes the protons, neutrons, and electrons. Atomic mass is given in atomic mass units (u) and is a weighted average of the isotopes of an element in the periodic table.
An atomic mass of 39 amu is equal to 19 protons and 20 neutrons. This is because the atomic mass is the sum of the protons and neutrons in the nucleus of an atom.
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 an element is the number of protons in the nucleus, which also determines the element's identity. The atomic mass is the total mass of an atom, which includes the protons, neutrons, and electrons. Atomic mass is given in atomic mass units (u) and is a weighted average of the isotopes of an element in the periodic table.
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)
A neutral atom of neon with atomic number 10 has 10 protons and 10 electrons. The mass number of 22 indicates the total number of protons and neutrons combined. Since the atomic number is 10, the number of neutrons is 22 - 10 = 12.
