If an atom were to change the number of protons it had than it would change the atomic number and therefore become a different element.
Radioactive decay is one example of this, for example, alpha decay is when a radioactive nucleus emits an alpha particle (2 protons + 2 neutrons) and in doing so, becomes a nucleus of a different element. Polonium-212 decays to Lead-208 in this way.

What will be the no of neutrons protons of hg having mass no 200 atomic no 80?
The number of protons = the atomic number. The number of neutrons = the mass number - the atomic number Protons = 80 Neutrons = 120 Also, for extra information, not that you need it, the element would be mercury.
If the nucleus had six protons how many electrons would the atom have?
It would likely have 6 neutrons which means it would have a mass of 12, hence Carbon-12, the most abundant isotope of C. If it had 8 neutrons (Carbon-14), it would be unstable and would decay by negative beta decay to stable Nitrogen-14, the most abundant isotope of N which has 7 protons and 7 neutons for a mass of 14.
If an isotope of oxygen has 8 protons 10 neutrons and 8 electrons its mass number is?
This certain isotope of oxygen would have a mass of about 18 because electrons weigh almost nothing.
How many protons electrons and neutrons are there in the ion?
Without knowing which nuclide is in question, it remains safe to say that regardless of the element, in an ion the atomic number or count of protons differs from the number of electrons - and thus the atom is overall not electrically neutral - the definition of an ion. With fewer electrons than protons, it would be a positively charged ion (cation); with more electrons than protons, it would be a negative ion (anion). If the atomic number (proton number) is P, the charge is x and the mass number is M, then protons = P neutrons = M- P and electrons is the algebraic sum of P and x.
What is the mass number for Fe?
The number of Neutrons and Protons in the nucleus.So it would be 26 Protons and 30 Neutrons so...26+30=56<so that is the mass number.
Does changing the number of protons in a atom make an ion?
Yes, changing the number of protons in an atom would change the element, not necessarily create an ion. An ion is formed when the number of electrons in the atom changes, leading to a charged particle.
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.
Which of these can vary without changing the identity of an element number?
The mass number can vary without changing the identity of an element, as it represents the number of protons and neutrons in the nucleus. Conversely, changing the number of protons would change the identity of the element, as it defines the element's atomic number.
Can a single element have more than one atomic number?
No, each element has a unique atomic number that corresponds to the number of protons in its nucleus. Changing the number of protons would change the element itself.
Why oxygen cannot have 9 protons?
Oxygen has 8 protons in its nucleus because it is its atomic number. Changing the number of protons would result in a different element altogether.
Do the number of protons for an ion differ from it's neutral atom?
The number of protons must be the same for the neutral isotopes and for the ions of a given element. A change of the number of protons would change the atomic number and the identity the chemical species.
Why must the number of protons always stay the same in an atom?
The number of protons in an atom determines its identity as a specific element. Changing the number of protons would result in a different element. Therefore, the number of protons must remain constant in order to maintain the stability and characteristics of the atom.
What subatomic particles could be changed without changing which element the atom?
You are probably referring to neutrons which are often found within the nucleus of an atom in numbers different from the protons. An atom of the element carbon, for instance, normally consists of 12 protons, 12 electrons and 12 neutrons. However, an isotope of carbon known as C13 consists of 12 protons, 12 electrons and 13 neutrons.
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.
What would change the number an atom into an atom of a different element?
A nuclear reaction of some sort ( not necessarily violent blast). there are various Isotopes of some elements- with differing atomic numbers.
If the number of neutrons in an atom is changed does the atom become a new element Why or why not?
Changing the number of neutrons in an atom does not change the element it belongs to because the element is determined by the number of protons in the nucleus. Changing the number of neutrons would result in an isotope of the same element, not a new element.
Why would sodium never have 12 protons?
Sodium has an atomic number of 11, which indicates the number of protons in its nucleus. Thus, sodium would never have 12 protons since that would change its identity to argon, which has an atomic number of 18.
