How many neutrons does atomic number 53 have?
How many neutrons does atomic number 53 have?
74
Solution. The atomic number of iodine (53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus. Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 – 53 = 74).

What is the atomic number 53?
Iodine
Iodine is a chemical element with symbol I and atomic number 53. Classified as a halogen, Iodine is a solid at room temperature.
What has 53 protons and 74 neutrons?
iodine
The most common, stable form of iodine has an atomic number of 53 (protons) and an atomic weight of 127 (53 protons plus 74 neutrons). Because its nucleus has the “correct” number of neutrons, it is stable and is not radioactive.
Why is silver called AG?
The symbol Ag derives from the Latin argentum and Sanskrit argunas from “bright”. The Latin word for silver is argentum. Silver has been known since ancient times.
Why is gold called gold?
The name is the Anglo-Saxon word for the metal and the symbol comes from the Latin ‘aurum’, gold.
Why does gold have 79 electrons?
A Gold (Au) atom has 79 protons and 79 electrons. 79 is its charge (atomic number), which is both its proton number and electron number. 197 is its mass (atomic mass), which is the sum of its proton number and neutron number. The neutron number can be calculated by subtracting the proton mass from the total mass.
