How many neutrons does krypton have?
Answer and explanation: Krypton has 48 neutrons. The atomic number of krypton is 36. This number also tells you how many protons there are in a krypton atom.
Note that the atomic nucleus is made up of protons and neutrons. And the number of particles present in the nucleus is called the mass number (also called the atomic mass). To find the number of neutrons in an atom, simply subtract the number of protons from the mass number.

In fact, the number of protons and electrons in an atom is the same only if the atom is neutral. The three atomic particles in an atom are protons that carry a positive charge, electrons that carry a negative charge, and neutrons that have no charge.
The mass number (symbol A, from the German word atomic weight), also called the atomic number or number of nucleons, is the total number of protons and neutrons (collectively called nucleons) in an atomic nucleus. The mass number is different for each isotope of a chemical element.
The number of electrons in a neutral atom equals the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the ordinal number (M) and the ordinal number (Z).
Understand that the isotopes of an element have different mass numbers but the same number of protons. You can use the periodic table to determine the element’s atomic number. The atomic number corresponds to the number of protons. In a balanced atom, the number of electrons equals the number of protons.
Since Kr or Krypton is a noble gas, it has a full valence shell or 8-electron byte.
a valence electron
Since crypto is on the far right of the periodic table, its outer shell is filled with eight electrons. The other noble gases, including argon and xenon, also have a complete outer shell with eight electrons. Noble gases have valence 0.
Inert gas, some of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn) and oganesson (Og).
Hydrogen has no neutrons, deuterium has one, and tritium has two. Hydrogen isotopes have mass numbers of one, two and three respectively. Their atomic symbols are therefore 1H, 2H and 3H. The atoms in these isotopes have an electron to balance the charge of a proton.
