take the mass number of boron-10 and subtract the atomic number then divide that number by mass number then multiply it by 100
The mass number of an isotope is the sum of its protons and neutrons. For oxygen, which has 8 protons, an isotope with nine neutrons would have a mass number of 8 (protons) + 9 (neutrons) = 17. Therefore, the mass number of this oxygen isotope is 17. This isotope is known as oxygen-17.
For each isotope the number of neutrons is different.Number of neutrons = Mass number of an isotope - 98
The mass number of an isotope is the sum of its protons and neutrons. In this case, the isotope of chlorine has 25 protons and 17 neutrons. Therefore, the mass number is 25 + 17 = 42. Thus, the mass number of this isotope of chlorine is 42.
The mass number of an isotope is the sum of its protons and neutrons. Oxygen has an atomic number of 8, meaning it has 8 protons. If the isotope has 9 neutrons, the mass number would be 8 protons + 9 neutrons = 17. Therefore, the mass number of this oxygen isotope is 17.
Depending on the isotope. Number of neutrons = Atomic mass of the isotope - 84
For each isotope the number of neutrons is different.Number of neutrons = Mass number of an isotope - 98
The mass number of an isotope is the sum of its protons and neutrons. Since silicon has 14 protons, the isotope with 15 neutrons would have a mass number of 14 (protons) + 15 (neutrons) = 29.
Depending on the isotope. Number of neutrons = Atomic mass of the isotope - 84
For each isotope of Md the number of neutrons is different.Number of neutrons = Mass number of a Md isotope -101
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 mass number of an isotope is the sum of its protons and neutrons. Silicon has an atomic number of 14, meaning it has 14 protons. If the isotope has 15 neutrons, the mass number would be 14 protons + 15 neutrons, which equals 29. Therefore, the mass number of the silicon isotope is 29.
The number of neutrons is different for each isotope. Number of neutrons = Atomic mass of an isotope - 104
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Tc isotope - 43
An isotope of indium has 77 protons and 115 neutrons. What is the mass number of this isotope
Subtract the atomic number of the isotope from its atomic mass number to obtain the number of neutrons in an isotope.
Each isotope has a different number of neutrons. Number of neutrons = Atomic mass of the astatine isotope - 85
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Tc isotope - 43
