Iodine. All isotopes of an element have the same number of protons, which is also the atomic number and identifies the element.
The neutral isotope of iodine 129I has 53 protons, 76 neutrons but 53 electrons.
The anion of 129I has 54 electrons (129I-).

What is the number on the periodic table that indicates the number of protons and neutrons in the nucleus of one atom of an element?
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.
How many protons and neutrons are in sodium based on periodic table?
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!
How do you find the number of protons and neutrons in 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.
How do you find the number of neutrons in a element using only mass and the element name?
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.
What element has 6 neutrons and protons?
The element with 6 neutrons and 6 protons is carbon.
What are found in each element on the periodic table?
Electrons, protons, neutrons
What is the number on the periodic table that indicates the number of protons and neutrons in the nucleus of one atom of an element?
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.
Which element has 30 protons?
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.
How do you determine the mass of an element?
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.
53 protons 74 neutrons in which element of the periodic table?
This is stable isotope of iodine - iodine-127.
How many protons and neutrons are in sodium based on periodic table?
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!
What element on the periodic table has 48 neutrons?
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.
How do you find the number of protons and neutrons in 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.
Is there oxygen in a proton?
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.
What is the sum of protons and neutrons known as an element?
The sum of protons and neutrons in an atom is known as the atomic mass or mass number of an element. It is typically shown as the whole number next to the element's symbol in the periodic table.
How do you find the number of neutrons in a element using only mass and the element name?
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.
What element has 6 neutrons and protons?
The element with 6 neutrons and 6 protons is carbon.
