17 сент. 2016 г. · Or if you mean “how to find how many,” here's how: protons = electrons = atomic number, neutrons = round(atomic mass) - atomic number.

24 авг. 2019 г. · The Atomic number uniquely identifies the Element and the Mass number is an indication of which isotope is under consideration.

29 мар. 2016 г. · For isotopes Z = protons number is the same , but differ by the mass number A = Z+ N( neutrons number) , so,= knowing Z then N= A-Z = neutrons ...

11 июн. 2024 г. · If Z is the atomic number, N is the number of neutrons, A is the mass number, we have · A = Z + N · For example, 92U235 means 92 protons (Z), and ...

30 нояб. 2017 г. · For the number of neutrons just take the mass number of the atom and subtract the number of protons. For example oxygen-18. Oxygen has 8 protons ...

27 июн. 2023 г. · The two numbers written next to and element denote the number of protons, neutrons and electrons. · The bottom number of carbon 12 is 6, meaning ...

8 дек. 2022 г. · An isotope is simply an atom of a particular element. Each element has configurations of “X” number of protons and varying numbers of neutrons.

22 июн. 2016 г. · By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom. To get a tutorial dm me.

11 мар. 2016 г. · Mass number of a particular isotope = number of protons + number of neutrons. Therefore subtract atomic number from the mass number to give the ...

5 апр. 2023 г. · The fact that each isotope has one proton makes them all variants of hydrogen: the identity of the isotope is given by the number of neutrons.
