Yes. the atomic weight is the averge atomic weight of the ions of an element, which differ because of their different number of neutrons. The weighted average is the same thing but takes into account what percentage of the element the specific ion is
Radium typically has 138 neutrons.
Protons and neutrons are present in nucleus. They are fixed.
14
Neutrons have the same mass as that of a proton. Neutrons and protons are present in the nucleus
The isotope 14C has 8 neutrons.
30 neutrons in Ni-58 isotope.
Protons have a positive charge, Electrons have a negative charge, and Neutrons have a neutral charge. Neutrons help to ground the charges of protons and electrons.
neucleons
This depends on the individual Atom.
One limitation of the weighted average cost of capital is that a firm may possibly end up having a negative Net Present value. This occurs if the weighted average cost of capital gives a discount rate that is too low.
Chlorine naturally occurs with mixed isotopes, and the number is an average of the atomic mass of those isotopes, in the proportion they are present. The isotopes have the same atomic number (protons), but their mass number can be different due to the presence of a different number of neutrons. These atoms of an element having a different number of neutrons are called isotopes.
The number of neutrons will vary for every isotope of an atom and is not possible to generalize for all the elements.
