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.
Changes its atomic number and the identity of the atom.
The Atom would become a different Element - for example, 6 protons gives Carbon while 7 protons give Nitrogen.
This atom become another chemical element.
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.
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.
This certain isotope of oxygen would have a mass of about 18 because electrons weigh almost nothing.
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.
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.
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.
If the number of electrons changes without the number of protons changing, the atom will become an ion, either positively or negatively charged depending upon whether the electron count decreased or increased, respectively.
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.
Atomic numbers are determined by the number of protons an atom has. The mass number is determined by the number of protons and neutrons. While the number of protons can't change (as the element itself would change), neutrons can and do vary. These are called isotopes.
No because the number of protons can not change. If it does it would then be Oxygen. Think of a proton as an id number or SSN.
An atom is made of smaller particles called protons, neutrons, and electrons. Protons and nuetrons are in the nucleus. The number of protons in a nucleus is the atomic number and defines the type of element the atom forms. The number of neutrons determines the isotope of an element. For example, the carbon-12 isotope has 6 protons and 6 neutrons, while the carbon-14 isotope has 6 protons and 8 neutrons. If the numbe of protons were to change, it would no longer be carbon.
No, the atomic number does not change when an ion is formed. The number of protons does not change when an ion is formed, so the atomic mass would not change.
The number of protons can not be changed in an atom, while the number of electrons can be.
The element transforms itself into another element because each element have a specific number of protons. If the number of protons changes, the element changes as well. The number of protons in an atom defines it elemental identity, so if the number of protons in an element increases by one it becomes another element. Although this reference doesn't really provide a direct answer, it does provide additional information that might be of interest: http://www.answers.com/topic/proton
The type of atom is now different from what it was. (It has a new identity.)
The element becomes a new element becuase the atomic number would change. For example if you added a proton to Hydrogen-atomic number 1, it would become helium-atomic number 2
The number of protons in an element will be the same regardless of the isotope or ion. To have a different number of protons would change what type of element it is. So, it is not necessary to say "how many protons does calcium-41 have?" because it is the same as saying "how many protons does calcium have?" The answer is the same in any case, the same as the atomic number, 20.
