6 protons
6 neutrons
Number of neutrons = Atomic mass of an isotope - Atomic number of the element; the atomic number of Lr is 103. Lawrencium has many isotopes and each isotope has a different number of neutrons.
Ununseptium, with the atomic number 117, has 117 protons and 117 electrons. Since it is a heavy and unstable element, the number of neutrons can vary depending on the isotope, but a common isotope of ununseptium might have around 176 neutrons.
oxygen has 8 protons as its atomic number is 8. The number of neutrons depends on the isotope. O-15 isotope will have 7 neutrons, O-16 isotope will have 8 neutrons. (Note: Mass number = Number of protons + number of neutrons)
Francium has 87 protons; the number of neutrons is different for each isotope and francium has approx. 40 isotopes and isomers. Number of neutrons = Atomic mass of the isotope - 87
The number of neutrons is the difference between the atomic mass of an isotope and the atomic number. Actinium has a great number of isotopes, each with a different mass or number of neutrons.
Promethium has 61 protons and electrons.For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 61
Promethium has 61 protons and electrons; For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 61
Californium has 98 protons and neutrons.For each isotope the number of neutrons is different.Number of neutrons = Mass number of an isotope - 98
Copernicium has 112 protons and electrons.For each isotope of Cn the number of neutrons is different. Number of neutrons = Mass number of an Cn isotope - 112
6 protons. The number of neutrons varies, but the most common isotope has 6 neutrons.
Number of neutrons = Atomic mass of an isotope - Atomic number of the element; the atomic number of Lr is 103. Lawrencium has many isotopes and each isotope has a different number of neutrons.
Americium has 95 protons and electrons. Number of neutrons: Atomic Mass of an isotope - number of protons
Ununseptium, with the atomic number 117, has 117 protons and 117 electrons. Since it is a heavy and unstable element, the number of neutrons can vary depending on the isotope, but a common isotope of ununseptium might have around 176 neutrons.
Technetium has 43 protons and 43 electrons. For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Tc isotope - 43
oxygen has 8 protons as its atomic number is 8. The number of neutrons depends on the isotope. O-15 isotope will have 7 neutrons, O-16 isotope will have 8 neutrons. (Note: Mass number = Number of protons + number of neutrons)
Protactinium has 91 protons and electrons; the number of neutrons is different for each isotope: Number of neutrons = Atomic Mass of the isotope - 91
Mendelevium has 101 protons and electrons.For each isotope the number of neutrons is different.Number of neutrons = Mass number of an isotope -101
