the answer is 109... im not positive that im right but if i am right heres what you do... subtract the Atomic Mass from the atomic number(number of protons.) :p
106 neutrons. Since you minus the number of protons which is the atomic number and the mass number which is the neutrons and protons added together.
72 protons
72 electrons
108 neutrons
* Number of Electrons: 72 * Number of Neutrons:106 * Number of Protons: 72 * Number of Electrons: 72 * Number of Neutrons: 106 * Number of Protons: 72
Hafnium has 72 electrons and protons; the number of neutrons is different for each isotope and depend on atomic mass of the isotope.
Number of neutrons = Atomic mass of an isotope - atomic number Atomic number of Cf is 98.
The atomic number of cesium is 55. The number of neutrons is the isotope mass number minus atomic number, or in this instance 86 neutrons.
Atomic mass is equal to the number of protons + neutrons present in the nuclide. The atomic number is defined as the number of protons in the nuclide. Therefore to find the number of neutrons use the formula: atomic mass = #protons + # neutrons solving for # of neutrons you get: # neutrons = atomic mass - # protons plug in the given values: #neutrons = 31 - 15 # neutrons = 16
* Number of Electrons: 72 * Number of Neutrons:106 * Number of Protons: 72 * Number of Electrons: 72 * Number of Neutrons: 106 * Number of Protons: 72
the atomic number of hafnium is 72, protons? 72, neutrons? 106, electrons? 72
Hafnium has 72 electrons and protons; the number of neutrons is different for each isotope and depend on atomic mass of the isotope.
The atomic number of hafnium is 72. So there is 72 protons.
To find the number of neutrons simply subtract the atomic number from the atomic mass. In this case there are two neutrons.
Number of neutrons = Atomic mass of an isotope - atomic number Atomic number of Cf is 98.
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of hassium is 108; each isotope of an element has a different number of neutrons and a different atomic mass.
The atomic number of cesium is 55. The number of neutrons is the isotope mass number minus atomic number, or in this instance 86 neutrons.
50 neutrons
The atomic number (number of protons) of the element is needed to tell the number of neutrons. Mass number = atomic number + number of neutrons.
Roentgenium-272 has 161 neutrons. Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of roentgenium is 111, but Rg has many isotopes each with a different atomic mass and number of electrons.
Mass number = Atomic number (or number of protons) + Number of neutrons
