Does there have to be the same number of protons and neutrons in the nucleus?

No. Even atoms of the same element will vary in the number of neutrons in their nucleus. For example, carbon (6 protons) has isotopes with 6, 7, and 8 neutrons. The most common isotope of hydrogen (1 proton) does not have any neutrons. While the most common isotopes of the lighter elements generally have the same number of protons and neutrons, heavier elements will have more neutrons than protons. For example the most common most stable isotope of uranium (92 protons) has 146 neutrons.

What do isotopes and nucleus have in common?
All the isotopes of a chemical element have the same atomic number, number of protons and number of neutrons.
What element has the same number of protons and neutrons in its nucleus as an alpha particle?
An alpha particle has 2 protons and 2 neutrons. That is the same as a helium nucleus.
Isotopes can have the same what?
Isotopes of an element have the same numbers of protons in the nucleus (and corresponding electrons). It's not so much "can have", as "do have". It's just a different number of neutrons that makes a different isotope.
How are isotopes different from one another?
Isotopes are atoms that have the same number of protons, but different number of neutrons in the nucleus of the atom. So the Carbon atom normally has 12 protons and 12 neutrons, but a few carbon atoms have 12 protons and 14 neutrons. The number of protons in the nucleus and electrons in the shell determine the properties of the element, but the extra neutrons can cause the element to be a little heavier or lighter than normal.
How are isotopes the same but different?
Isotopes are different forms of the same element which have different numbers of neutrons in their atomic nuclei. A given element is identified by the number of protons in its nucleus; that's its atomic number. Two different isotopes of the same element have the same number of protons, but each has a different number of neutrons in its nucleus. Different isotopes of the same element are chemically the same.
What do isotopes and nucleus have in common?
All the isotopes of a chemical element have the same atomic number, number of protons and number of neutrons.
Does a nucleus have the same number of protons and electrons?
The nucleus of an atom contains only protons and neutrons; there are never any electrons in the nucleus. The number of neutrons is generally equal to or greater than the number of protons.
What element has the same number of protons and neutrons in its nucleus as an alpha particle?
An alpha particle has 2 protons and 2 neutrons. That is the same as a helium nucleus.
What atom has the same number of protons and a different number of neutrons from other atoms of the same element?
Isotopes of an element have the same number of protons but differing numbers of neutrons in the nucleus.
Isotopes can have the same what?
Isotopes of an element have the same numbers of protons in the nucleus (and corresponding electrons). It's not so much "can have", as "do have". It's just a different number of neutrons that makes a different isotope.
How does the mass of a nucleus differ from the mass of an electron?
There is no simple answer.The mass of a nucleus depends on the number of neutrons and protons in the nucleus. The number of protons in the nucleus depends on the element. Moreover, the number of neutrons can vary between isotopes of the same element.
The number of protons plus neutrons in an alpha particle?
2 protons and 2 neutrons. An alpha particle is the same as a helium nucleus.
What identifies an atoms as being of the same element?
The number of protons and neutrons in the nucleus.
Do protons circle the nucleus of an atom?
Nuclei of atoms contain protons (+) and neutrons. The electrons (-) circle the nucleus on orbitals, forming the electron cloud. In a balanced or neutral atom, there will be the same number of protons in the nucleus as there are electrons outside of the nucleus. The number of neutrons can vary within the same element; that's how you get isotopes (e.g. Carbon-13 has 6 protons, 6 electrons, and 7 neutrons...The 13 is the atomic mass representing the sum of the protons and neutrons)
What does the atom of?
An atom has a nucleus composed of protons and usually neutrons as well (there is only one kind of atom which has no neutrons, which is the hydrogen 1 isotope) and it also has electrons surrounding the nucleus, with the same number of electrons as the number of protons in the neutrons.
How many protons and neutrons are there in the nucleus of an atom that has an atomic number of 84 and a mass number of 210?
84 protons, the same as the atomic number, and (210 - 84) or 126 neutrons. The numbers of protons and neutrons together equals the mass number.
The main difference between isotopes of the same element has to dowith the number of?
The difference between isotopes of the same element have to do with the number of neutrons present in the nucleus of the atom. Isotopes are atoms of an element that contain the same number of protons, but different numbers of neutrons and therefore different mass.
