Why doesnt the number of protons change for a single element while the neutrons and electrons can?

The protons don't change because if the number of protons changes, the type of element the atom is changes. The number of protons determine the species of the atom.

How many protons and neutrons and electrons does the element gold have?
In a regular sample of the element of gold, meaning no change done to it, then there will be 79 protons and 118 neutrons
How many subatomic particles does krypton have?
Protons 36 Neutrons 48 (for the most stable isotope, Kr-84) Electrons 36
In the atom what type of particle determines the element that atoms represent?
proton you can change the number of neutrons and electrons and still have the same element
How many protons electrons and neutrons in calcium-44?
Ca-46 is an isotope of the calcium found on the periodic table. The atomic number is equivalent to how many protons the atom has and tells the identity of the element, if the number of protons is changed/ atomic mass number, the element would transmutate into another element. Thus, Ca always has 20 protons. Because it is not Ca++ or Ca- it is not changing the charge so no electrons are moving either. This means the number 46 is refering to a change in neutron in the nucleus of the atom, hence it is called an isotope. 46 is the number of protons plus neutrons so the isotope of Calcium has 20 protons, 20 electrons and 26 neutrons, or 46-20=26. Hope this clarifies things.
How man protons and neutrons does aluminum ion Al 3?
13 protons and 14 neutrons. The fact that its an ion doesn't change that ... only the number of electrons.

What effect produced by changing the number of neutrons in the nucleus of an atom?
What differentiates one element from another (like Hydrogen from Helium) is the number of protons in the nucleus. When protons are added (as happens in nuclear fusion) or subtracted (nuclear fission), the element transmutes into another element. When the number of Protons are changed, both the Electrons and Neutron (numbers) will change too. Protons are paired with electrons. Protons + Electrons = Neutrons, thus reinforcing that both the Electrons and Neutrons will change when the number of Protons has.
Why doesn't the number of protons change for a single element while the neutrons and electrons can?
Because the no. of protons is the primary property through which we call an atom to be of a particular element.
Which particles that make up an atom are involved in nuclear reactions?
Protons, electrons, and neutrons are the subatomic particles that are involved in nuclear reactions.

Protons 36 Neutrons 48 (for the most stable isotope, Kr-84) Electrons 36
Why is the atomic mass the same as the total number of protons and neutrons in the nucleus?
The neutrons and protons are in the nucleus which determines the element/isotope. The electrons however define the net charge (ie. positive if there are less electrons then protons and negative if more) and it can be changed more easily, than changing the amount of neutrons . Another reason is that electrons have a tiny mass compared to the protons and neutrons and it wouldn't change the mass number by all that much.
Do carbon-12 and carbon-14 have the same number of protons?
yes no matter what the same element will have exactly the same amount of protons only the neutrons and electrons change!
How may protons neutrons and electrons are in isotope?
All the elements on the periodic table differ in their atomic number (the number of protons in the nucleus) for example carbon has 6 protons in its nucleus). Any change in the number of protons and the element is given a different name (7 protons would be nitrogen). As well as protons, there are neutrons in the nucleus. The number of these can change within a single element, for example the most common form of carbon (carbon 12) has 6 neutrons and 6 protons giving it an atomic mass of 12, however a less common carbon 13 isotope exists which has 7 neutrons and 6 protons (hence has an atomic mass of 13). Now with respect tp the electrons, in a neutral element (one with no negative or positive charge) tho number of electrons always equals the number of protons (so carbon will have 6 electrons in both of its isotopes).
Are the number of protons always equal to the number of neutrons?
No, in fact, they rarely are equal. There are different forms of the same type of atom. For example, there are three isotopes of Hydrogen, an element that has one proton. Hydrogen-1 has no neutrons. Hydrogen-2 has one neutron. Hydrogen-3 has two neutrons.
