I am understanding you to mean an iron-57 ion with a charge of 3+.
The atomic number of Fe is 26, which means that all Fe atoms or ions have 26 protons in their nuclei.
In a neutral Fe atom, the number of electrons would be the same as the number of protons, which is 26. The charge on the Fe ion is 3+, which means the Fe atom has given up 3 electrons. So the number of electrons in an Fe3+ ion is 26-3, which is 23.
The mass number of iron-57 = 57. The mass number is the sum of protons and neutrons in the atomic nuclei of iron-57 atoms. We know the number of protons is 26. The number of neutrons = mass number - the number of protons, which is 57-26 = 31 neutrons.
To summarize:
The number of protons in all Fe atoms is 26.
The number of electrons in an any Fe3+ ion is 23.
The number of neutrons in an iron-57 atom is 31.
To determine the mass number of nitrogen, you would need to know the number of protons and neutrons in its nucleus. Nitrogen has 7 protons, so the mass number can be calculated by adding the number of protons (7) to the number of neutrons in the nucleus.
The mass number of an atom is the sum of the protons and neutrons in its nucleus. Therefore, for an atom of calcium with 20 protons and 20 neutrons, the mass number would be 40.
79; the mass number is the sum of the protons and neutrons, and the atomic number is the number of protons. So if you take the mass number (protons + neutrons) minus the atomic number (protons), you get the number of neutrons.
The symbol for a sodium isotope with 12 neutrons would be "Na-23". This notation indicates the element symbol "Na" for sodium and the total number of protons and neutrons in the nucleus (12 neutrons + 11 protons = atomic mass number 23).
Unundeptium has 117 protons and electrons; the number of neutrons is 176 or 177, depending on the isotope.
The neutron has no charge so changing the number of neutrons in the nucleus would not change the charge of the nucleus.
A nucleus having 11 protons and 12 neutrons is a sodium nucleus, no of neutrons may differ in case of isotopes.
If a nucleus contained no neutrons, there would only be protons all with a positive charge which would be very unstable. Neutrons help space out the positive charges and bind the nucleus together.
All chlorine atoms contain 17 protons in each nucleus. The mass number is the sum of the numbers of protons and neutrons; therefore, the atom described in the question has a mass number of 35.
If the binding energy of a nucleus was zero, the nucleus would not be stable and would disintegrate. The nucleus relies on the binding energy to hold its protons and neutrons together. Without this binding energy, the nucleus would break apart into individual protons and neutrons.
Protons and Neutrons compose the nucleus of the atom. They are surrounded by a cloud of electrons. If our universe was an atom, the sun would be the nucleus (with protons and neutrons) and the orbiting planets would be the electrons.
Atomic mass= Atomic no. + no. of neutrons So when the atomic no. is subtracted from the atomic mass, the result would be equal to the number of neutrons present in the nucleus of the atom of the element.
The nucleus of an atom contains neutrons and protons. Almost all of the mass in an atom is made up from the protons and neutrons in the nucleus. Because the nucleus is only made up of protons and neutrons, it is positively charged. Physicists believe that there is a cluster of Protons and Neutrons within an Atom's nucleus. Friend Premier is quite right. So instead saying inside the nucleus it would be apt to say that nucleus is made up of...
The atomic particles that make up an alpha are two protons and two neutrons. The subatomic particles are contained within the neutrons & protons and there are too many to list here, plus I don't know all of them.
That would be the nucleus.
The nucleus would become unstable because you need a certain amount of neutrons, electrons, and protons for it to be stable.
In this nuclear reaction, the total number of neutrons emitted would depend on the specific reaction and energy of the collision. However, typically when a californium-249 nucleus is bombarded by a carbon-12 nucleus to produce a Rf nucleus, several neutrons are emitted in the process. The exact number of neutrons emitted can vary.
