Question

Symbol for uranium atom is 92U238. How many neutrons are present in this atom?​

Answer 1

Answer:

238

- 92

146 neutrons are present in this atom Answer!

Explanation:

The amount of protons present in an atom is the same as the amount of electrons, the amount of protons in an atom is it's atomic number so the amount of electrons can also be considered it's atomic number as long as they are the same which is true usually. The atomic mass is the sum of the number of neutrons and protons the atom has, so if we subtract the atomic number or protons from the atomic mass we can find the number of neutrons in the atom, the number on the right of the symbol is 238 which is the atomic mass and the number on the left is 92 which is the atomic number or the amount of protons so we can just subtract them from the atomic mass to get the electrons.
