How many of these particles are there in a neutral atom of U 92 238 Electrons.

There are 92 electrons present in the neutral atom of U 92 238 . Natural Decay Series of Uranium- 238 Uranium has an atomic number of 92 which means there are 92 protons and 92 electrons in the atomic structure. A much bigger atom with 92 protons in its nucleus is a uranium atom, because uranium is element 92 .

How many of these particles are there in a neutral atom of U 92 238 . neutrons

There are 146 neutrons present in the neutral atom of U 92 238 . U- 238 has 146 neutrons in the nucleus, but the number of neutrons can vary from 141 to 146 . Because uranium is radioactive, it is constantly emitting particles and changing into other elements. Natural Decay Series of Uranium- 238 Uranium has an atomic number of 92 which means there are 92 protons and 92 electrons in the atomic structure. A much bigger atom with 92 protons in its nucleus is a uranium atom, because uranium is element 92 .

How many of these particles are there in an neutral atom of U 92 238 protons

There are 92 Protons present in the neutral atom of U 92 238 . Natural Decay Series of Uranium- 238 . Uranium has an atomic number of 92 which means there are 92 protons and 92 electrons in the atomic structure. A much bigger atom with 92 protons in its nucleus is a uranium atom because uranium is element 92 .
