Yes, some elements can have the same number of neutrons despite being different elements; these are called isotopes. Isotopes are variants of a chemical element that have the same number of protons (and therefore the same atomic number) but different numbers of neutrons. For example, carbon-12 and carbon-14 are both isotopes of carbon, with 6 neutrons and 8 neutrons, respectively. This phenomenon occurs because the Atomic Mass of an element is determined by the total number of protons and neutrons, allowing for variations in neutron count while maintaining the same atomic identity.
PROTONS. Isotopes of an element may have a different number of neutrons.
As for all other elements: neutrons, protons and electrons.
As all other chemical elements promethium contain protons (61), electrons (61) and a variable number of neutrons depending on the isotope.
A "superscript" number before the symbol for the element - eg. 11C 12C 13C 14C Denotes the four isotopes of the element Carbon. The superscript number is a count of the total number of "nucleons" (protons and neutrons) in the atomic nucleus of the atom. If you subtract the elements "atomic number" (which is the number of Protons that element has) from the Isotope (superscript) number you get the number of Neutrons in that isotope. From this you will be able to deduce that isotopes of elements are caused by a variation in the number of neutrons in an atom of an element.
It depends on the atom and isotope. In the most common isotope of hydrogen, there are no neutrons. In other light elements, the numbers of protons and neutrons are often equal. In heavier elements, there are more neutrons than protons in most isotopes.
Atoms of all elements can have neutrons in them. Only the element hydrogen has an isotope whose atoms do not contain neutrons, but all other isotopes of hydrogen have neutrons in them. In the heavier elements the number of neutrons always exceeds the number of protons in the atom.
the atom is an isotope
No. Some may have different numbers of neutrons. Atoms of the same element (atoms with the same number of protons in the nucleus) may have different numbers of neutrons, and so will have different masses. As an example, chlorine is a mixture of different isotopes with some of the atoms having different neutrons numbers.
Yes, it is possible.
The Periodic Table of the Elements includes most of this information (but not the number of neutrons). The Chart of the Nuclides (or Table of the Isotopes) includes all of the information.
An element with 148 neutrons in its nucleus is usually Gadolinium (Gd) with an atomic number of 64, as its atomic mass is approximately 157. There may be isotopes of other elements with 148 neutrons as well.
Sodium is an element. It is not made of any other elements. If you are reffering to the fundamental particles that make sodium, it is 11 protons, 11 electrons and any number of neutrons, depending on the isotope. 11 or 12 neutrons would be acceptable as an answer.
PROTONS. Isotopes of an element may have a different number of neutrons.

As all other chemical elements promethium contain protons (61), electrons (61) and a variable number of neutrons depending on the isotope.
Nitrogen-14: 7 Protons, 7 Electrons, 7 Neutrons To work this out in the future for other elements: Protons = Atomic Number Electrons = Atomic Number Neutrons = Atomic Mass - Atomic Number Hope this helps!
Elements are defined by the number of protons contained in the nucleus of their atoms. The number of electrons (the same as protons in neutral atoms) determine an elements chemical interactios with other elements. The number of neutrons (which can vary) determines an element's mass and relative stability.
