An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance.
They could determine it by counting their total amount of miles mark went by the directions he went to walk those miles.
By definition, we have that the number of neutrons is given by:
# neutrons = atomic mass - # protons
We know that the atomic mass is equal to 84.
We know the atomic number of Krypton is equal to 36. This means that the Krypton has 36 protons and 36 electrons.
Therefore, substituting values we have:
# neutrons = 84 - 36
# neutrons = 48
Answer:
The Krypton has 48 neutrons
