How do the numbers of protons neutrons and electrons for an element compare?

In the neutral state, all atoms of the same element contain equal numbers of protons and electrons. However, most elements have atoms with different numbers of neutrons. These are called isotopes.


Do Eletrically neutral element have equal numbers of electrons and neutrons?

Electrically neutral elements have equal numbers of electrons and protons. A stable element has equal numbers of protons and neutrons. Thus, the answer to the question ''Do Eletrically neutral element have equal numbers of electrons and neutrons?'' depends on the stability of the element i.e. if stable then yes and if unstable than might not.


The mass number of an elements is equal to?

the total number of protons and neutrons in the nucleus.


What is the name given to atoms of the same element that have the same number of protons?

Atoms of the same element cannot have different numbers of protons. Different numbers of protons mean different elements. An atom with the a different number of neutrons is called an isotope.


Isotopes of uncharged elements have different numbers of which of these?

Isotopes of an element have nuclei with the same number of protons (the same atomic number) but different numbers of neutrons Neutrons (:


What are elements with identical number for protons and different number of neutrons called?

The answer you are looking for is "isotopes" HOWEVER, please note you CAN NOT HAVE 2 elements with the same number of PROTONS. This is because the number of protons DEFINES an element. Isotopes are the SAME element but with differing numbers of neutrons.


Is gold a proton?

Yes it does. All elements have electrons, protons, and neutrons.


What name is given to elements wih the same number of protons but differing numbers of neutrons?

They are called as isotopes of the given element.


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.


What is the atomic number of an atom that has 2 protons and 3 neutrons?

5: The mass number of an isotope is always the sum of the numbers of protons and neutrons in a nucleus of elements of the isotope.


Atom of a particular element has a unique and characteristic number of these particles?

Each element has a unique number of protons. If another atom has the same number of protons as that element, it is the same element.


An atoms mass number equals the combination of what two things?

The mass number of an element is equal to the sum of the elements neutrons and protons.
