What has promethium in it?
As all other chemical elements promethium contain protons (61), electrons (61) and a variable number of neutrons depending on the isotope.
Is the number of protons greater than the number of electrons in an atom?
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.
Which symbols represents represents atoms that are isotopes of each other?
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.
How do the numbers of protons and neutrons compare in stable atoms?
The majority of stable atoms have slightly more neutrons than protons, but the numbers are similar. The biggest exception is hydrogen, which has a stable isotope having one proton and no neutrons. Many of the lighter elements have stable isotopes in which the number of protons and the number of neutrons is the same. But as the elements get heavier, we increasingly find that stable isotopes have more neutrons than protons. This is an understandable pattern. Protons, all of which have a positive charge, repel each other. It is the neutrons which act as a kind of nuclear glue, holding the nucleus together against the repulsive force that protons exert on each other. As the nucleus gets bigger, more neutrons are needed to hold it together.
What are the sub-atomic particles of uranium?
Protons, neutrons and electrons - as in all the other chemical elements.
Do atoms have neutrons in them?
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.
What is an atom of same elements that differs in the number of neutrons compared to other atoms of the element?
the atom is an isotope
Are all atoms of a given element identical to one another and different from atoms of other elements?
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.
What is the number of protons electrons and neutrons in n-14?
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!
If an atom has the same number of protons and neutrons is it most likely to bond with other atoms?
Yes, it is possible.
What elements make sodium?
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.

Distinguishes one element from another element?
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.
What are most of the elements made of?
Elements are not made of other elements. They are made of protons, neutrons, and electrons. They all differ in configuration.
