An atoms protons cannot change.
The number of neutrons can change (gain or lose) to form an isotope (ex. Hydrogen naturally has no neutrons. But it can gain neutrons to form Heavy Hydrogen, or in other words, a Hydrogen Isotope).
An atom can gain or lose electrons to form an ion. Usually an atom will gain or lose electrons to fill its valence (outermost) shell. It takes just as much energy to gain an electron as it is to lose one, so an atom will always look to lose or gain the least amount of electrons possible. (ex. Oxygen has 6 valence electrons. It will look to gain 2 electrons, rather than lose 6).
Protons: DO NOT CHANGE
Neutrons: Can change to form an isotope
Electrons: Can change to form an ion

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 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.
How many subatomic particles does krypton have?
Protons 36 Neutrons 48 (for the most stable isotope, Kr-84) Electrons 36
Why doesnt the number of protons change for a single element while the neutrons and electrons can?
The number of protons in an atom determines its identity as a specific element. Changing the number of protons would change the element. Neutrons and electrons can be added or removed without changing the identity of the element since they do not affect the element's chemical properties.
How many protons neutrons and electrons does Fe-56 have?
It doesn't matter if it's 56Fe or 49Fe; the number of protons in an atom of iron will remain constant. Why? Because if there was one more electron, it wouldn't be Fe anymore: it'd be cobalt (Co). The number of protons determines the element, the only thing that can change regarding the nuclear makeup of an atom without changing the element is the number of electrons. The 56 stands for the atomic weight of that particular isotope of iron. If each neutron and each proton weigh 1 amu each, then the atomic weight minus the number of protons will give you the number of neutrons.
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
The electric change of protons in the nucleus is the?
Protons have a positive charge, neutrons are neutral, and electrons have a negative charge.
When neutrons electrons and protons leave the atom what happens to the charge on the atom?
If neutrons, electrons, and protons leave the atom, the charge on the atom will change based on the number of protons and electrons that have left. Protons and electrons have opposite charges, so if electrons leave, the atom becomes positively charged, and if protons leave, the atom becomes negatively charged. Neutrons do not affect the charge of the atom since they are neutral.
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.
Where arw protons and neutrons found?
Matter and change a small amount of matter in the universe. Matter has mass and volume and is made of atoms. (atoms have) protons neutrons and electrons. Protons neutrons and electrons are found in everything from (pen,book,bread,pillow case, etc.)
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.
Is it true that Rubbing converts neutrons to protons increasing the charge?
No, rubbing does not convert neutrons to protons. Neutrons and protons are fundamental particles present in the nucleus of an atom and cannot be interconverted by rubbing. Rubbing may generate static electricity by transferring electrons between objects, but it does not change the fundamental composition of atomic nuclei.
Why is the atomic mass the same as the total number of protons and neutrons in the nucleus?
The atomic mass is the sum of the number of protons and neutrons in the nucleus because protons and neutrons have a mass of approximately 1 atomic mass unit each. Electrons are much lighter and do not significantly contribute to the overall mass of the atom.
How many subatomic particles does krypton have?
Protons 36 Neutrons 48 (for the most stable isotope, Kr-84) Electrons 36
Is it true that the nucleus is an atomic particle that has no atomic change?
the nucleus is made of protons and neutrons together. the protons have a positive charge and the neutrons have no charge [electrons circle the nucleus and have a negative charge]
What can be added or taken away from an atom to change the atomic mass?
The atomic mass of an atom can be changed by adding or removing subatomic particles. By adding or removing protons, neutrons, or electrons, the atomic mass will be altered. Changing the number of protons will change the element, while changing the number of neutrons will create isotopes of the same element.
Consider the silicon 29 isotope How many protons and neutrons and electrons will it have?
All silicon atoms have 14 electrons and 14 protons. That is a rule that every silicon atom must follow. On the periodic table, the number next to the atom is the number of electrons/protons in an atom (silicon is the 14th element listed on the periodic table, hence the 14 electrons and 14 protons). The number "29" is the number of protons and neutrons together. This number can change with changing isotopes. So, if every silicon atom must have 14 protons, and 29 is the number of protons and neutrons together, so the number of neutrons must be 29 minus 14. Final: 14 protons 14 electrons 15 neutrons
