This is stable isotope of iodine - iodine-127.
Electrons, protons, neutrons
The number on the periodic table that indicates the number of protons and neutrons in the nucleus of an atom is the atomic mass number, which is typically located on the top of the element's symbol. It is the sum of the number of protons and neutrons in the nucleus of an atom.
30 protons means element 30 from the periodic table, which is Zinc. Although it usually doesn't have 30 neutrons, and I doubt that would be a stable isotope. Stable zinc isotopes have 34 and 36 neutrons.
There are 11 protons and 12 neutrons. And that does not depend on the periodic table. Sodium had 11 protons and 12 neutrons long before the periodic table, or even human, beings existed!
The mass of an element is the sum of the protons and neutrons in an atom. It is usually listed right on the periodic table.
An element with 48 neutrons would most likely be cadmium (Cd) on the periodic table. Cadmium has an atomic number of 48, which means it has 48 protons. Adding the number of protons and neutrons gives the mass number of an element.
The number of protons in an element is equal to its atomic number, which is found on the periodic table. To find the number of neutrons, subtract the atomic number from the atomic mass of the element.
oxygen is a element one the periodic table, as such it is made up of protons electrons and neutrons. so there are protons in oxygen but there is not oxygen in protons.
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
To find the number of neutrons in an element, subtract the atomic number (number of protons) from the atomic mass number (rounded mass of the element). The atomic number can be determined from the element's position on the periodic table.
The number of protons defines the element. If an atom has six atoms, then it can only be carbon. If it has six neutrons, then it is 12C.
No. Atoms on the Periodic Table are listed by element in order of atomic number, which is the number of protons an atom contains. The number of neutrons in the atoms of an element usually varies among several isotopes.
