a negative decimal number, a rational number, a nice number
238 is 28% of 850
Number of neutrons = Mass number - atomic number = 238 - 92 = 146
Uranium-238 has 92 protons, 92 electrons and 146 neutrons.The mass number is 238 and the atomic number is 92.
They represent the number of nucleons.
No element has the atomic number 238. At present, the periodic table only goes up to atomic number 118.
Protons = 92 Neutrons 238-92 = 146

dah number is 238
As an even number greater than 2, 238 is divisible by 2 and therefore composite. Its positive integer factors are: 1, 2, 7, 14, 17, 34, 119, 238
238 Atomic mass: 238,050 788 247 ± 0,000 002 044 u.a. Atomic number: 92
The number of neutrons in an atom is easily calculated by taking the mass number and subtracting the atomic number. Take for example, Uranium: the mass number on the periodic table is 238, while the atomic number is 92. Take the difference of 238 and 92 and that will be equal to the number of neutrons. 238-92=146
