In general, atoms with atomic number equal to or greater than 21, will have more neutrons than protons in order to minimize the proton-proton repulsion within the neucleus and to maximize the stability of the nucleus / atom.
The pair below that describes isotopes of the same element is B, an atom with 6 protons and 6 neutrons-an atom with 6 protons. It is not A, an atom with 6 protons and 8 neutrons- an atom with 8 protons and 6 neutrons. Isotopes of the same element have the same number of protons and electrons, which is the atomic number of the element.
Atoms with unequal numbers of protons and electrons are called ions. In general, an ion is a charged particle, and if we have any atom that has an unequal number of protons and electrons, it has a charge imbalance, and will have an overall net charge. This charge will be positive if the number of electrons is less than the number of protons, or it will be negative if the number of electrons is more than the number of protons. In either case, that atom will end up with an overall net charge (either positive or negative) and will be considered an ion. Lastly, an anion is an atom with a negative electrical charge (a negative ion), and a cation is an atom with a positive electrical charge (a positive ion).ions.
An atom with 55 protons is a cesium atom. The mass number is the sum of the numbers of protons and neutrons, in this instance 131. Therefore, the atom is Cs-131.
An atom's mass number is the total number of protons and neutrons in its nucleus. It is used to identify isotopes of an element since isotopes of the same element have the same number of protons but different numbers of neutrons.
All the protons and neutrons are located in the nucleus (center) Protons are positvely charged (red) neutrons are green, electrons are negatively charged and yellow
Radioactive
An atom does not have to have equal numbers of protons and electrons, but it needs to have the same number of protons and electrons to be electrically neutral. Having an unequal number of neutrons in an atom will result in isotopes of the same element with different atomic masses.
neutrons in order to be stable. The number of protons determines the element's identity, while the stability of the nucleus is influenced by the balance of protons and neutrons. Isotopes can have different numbers of neutrons while maintaining the same number of protons.
These numbers actually vary between atom to atom.
The atomic mass of an atom is the total mass of protons, neutrons, and electrons in the atom, measured in atomic mass units (amu). It is approximately equal to the sum of the number of protons and neutrons in the atom's nucleus.

An atom that has more neutrons than protons is called an Isotope.
protons and neutrons are located in the atom's nucleus.
the number of protons and neutrons in an atom. Atomic mass is found by adding together the individual masses of the numbers of protons, neutrons, and electrons in the atom. --> Atomic Mass = protons + neutrons
Protons, neutrons, and electrons are subunits present in equal numbers in an atom. The number of protons in an atom is equal to the number of electrons, while the number of neutrons can vary in different isotopes of an element.
An atom's mass number is determined by the sum of its protons and neutrons. Protons have a positive charge and determine the element's identity, while neutrons help stabilize the nucleus and contribute to the atom's mass.
