What is the atomic mass of krypton 92?

Krypton is a non meta element. Atomic mass of it is 35.


When uranium 235 is struck with a neutron the krypton 92 and barium 141 nuclei are produced along with some neutrons how many neutrons are produced?

The average number of neutrons per nuclear fission is 2,5.


What is the half-life of barium and krypton and any other radioactive byproducts that are formed from nuclear fission?

This is an extensive subject, I cannot summarise all the isotopes formed into one answer. I suggest you go to the Wikipedia link given below, if that is not detailed enough there are other tables and charts available, an internet search should find several.


How many full orbitals and half-full orbitals are there in valence shell of krypton?

Krypton is a noble gas and hence has stable electronic configuration. Its valence shell configuration is 4s2 4p6 . Therefore, it has 1-s and 3-p full orbitals in its valence shell.


Are Barium-141 and krypton-92 produced by the bombardment of uranium-235 with a neutron?

Yes, because when you begin bombarding radioactive elements with neutrons, each reaction will result in more neutrons, which will then continue to bombard more elements, et cetera, and a chain reaction will occur. In this equation, the number above the "/" is the atomic mass of the isotope, and the number below is the atomic number of the element. The reaction results in Uranium splitting into an isotope of Barium, an isotope of Krypton, and then three more neutrons (a product of the said chain reaction). 235/92 Uranium + 1/0 N ---> 141/56 Barium + 92/36 Krypton + 3(1/0 N) Another note: When balancing nuclear equations, all you have to do is make sure the total number or atomic masses on each side of the equation are equal, and that the total number of atomic numbers on each side of the equation are equal.
