The 131 number is the mass number: the sum of the number of protons and neutrons. Iodine has 53 protons and will have 53 electrons if its a neutral atom. To find the number of neutrons, just subtract the mass number with the number of protons 131 - 53 = 78 neutrons. See link below for periodic table.

∙ 14y agoWith 131 particles in the nucleus, Iodine will have 78 neutrons. The atomic number of Iodine (53) never changes, and the atomic number of an element is the number of protons it has. Therefore, 131 particles (protons or neutrons) minus 53 protons = 78 neutrons.
There are 131 nucleons in the atom of iodine-131. This includes 53 protons and 78 neutrons.

∙ 14y agoIodine has an atomic number of 53. The number of neutrons is always equal to the mass number minus the atomic number; in this instance 131 - 53 = 78 neutrons.

What does the nucleons carry in atom?
the nucleons contain neutrons and protons in it
What is a generic name for the subatomic particles in the nucleus of an atom?
Nucleons, comprising protons and neutrons, are the generic name for the subatomic particles found in the nucleus of an atom.
Where is the nucleon located in an atom?
In the nucleus of the atom. The protons and neutrons of an atom are together collectively known as nucleons.
Protons and neutrons together are known as?
no there are different elements, and you can check a periodic table for more information.
How many protons electron neutrons and nucleons in a barium atom?
Proton = 1 Neutron = 1 Electron = 0.00054
What does the nucleons carry in atom?
the nucleons contain neutrons and protons in it
What is a generic name for the subatomic particles in the nucleus of an atom?
Nucleons, comprising protons and neutrons, are the generic name for the subatomic particles found in the nucleus of an atom.
What are protons and neutrons called?
Protons and neutrons are collectively called nucleons, which are particles found in the nucleus of an atom. Nucleons are responsible for the majority of an atom's mass and exist alongside electrons in an atom.
Essentially all of the mass of an atom is due to the?
nucleons
What are nucleons in the nucleus?
Nucleons are particles are are included in the nucleus of an atom. These include neutrons and protons (and their anti-matter pairs).
Particles is found in the nucleus of an atom?
Particles found in the nucleus of an atom are named as nucleons. There are mainly two type of nucleons. They are protons and neutrons. Protons are having positive charge but neutron is chargeless. To keep these nucleons together a particle known as pi mesons are exchanged between the nucleons.
Where is the nucleon located in an atom?
In the nucleus of the atom. The protons and neutrons of an atom are together collectively known as nucleons.
How many nucleon are present in phosphorus?
Phosphorus has 31 nucleons, which include 15 protons and 16 neutrons.
Which particles are found in the nucleus of the atom?
They're called nucleons. The two types of nucleons are protons and neutrons. Protons are positively charged nucleons and determine, in an atom, what element that atom is. Neutrons have no charge and just supposedly add mass to an atom.
What is the opposite of nucleons?
The opposite of nucleons would be anti-nucleons, which are particles composed of antiquarks and anti-protons. Anti-nucleons have opposite quantum numbers compared to nucleons, such as baryon number and strangeness.
How do you find the number of nucleons?
To find the number of nucleons in an atom, you add the number of protons and the number of neutrons together. Nucleons are the collective term for protons and neutrons found in the nucleus of an atom.
What is a proton or neutron as a component of the centre of an atom?
They are collectively known as nucleons, and together, all of them form the nucleus of an atom.
