42 total mass -20 protons = 22 neutrons
If you think to stable isotope Ca-135 this have 80 neutrons.
For Ca isotope 40 it is 20 neutrons and 20 protons, but there are 5 other naturally occurring (>2%) Ca-isotopes with mass numbers ranging from 42 - 48. Remember: p + n = mass number, so n = m - p
The mass number of an isotope is the sum of its protons and neutrons. Calcium (Ca) has an atomic number of 20, meaning it has 20 protons. If the isotope has 24 neutrons, the mass number would be 20 protons + 24 neutrons = 44. Therefore, the mass number of this calcium isotope is 44.
The isotope 293Uuo has 175 neutrons and the he isotope 294Uuo has 176 neutrons.
The isotope has 20 protons and 24 neutrons. This isotope is called calcium-44, and it is a stable isotope of calcium.
Francium has 87 protons and electrons; the number of neutrons is different for each isotope and francium has ca. 40 isotopes ad isomers. Number of neutrons = Atomic mass of the isotope - 87
If the isotope existed, it would have 16 neutrons.
If the isotope existed, it would have 16 neutrons.
Cl-35 isotope has 18 neutrons Cl-37 isotope has 20 neutrons
For each isotope of Md the number of neutrons is different.Number of neutrons = Mass number of a Md isotope -101
10 neutrons
The isotope 14C has 8 neutrons.
