Answer:
92; 146
Explanation:
Uranium has 92 protons, and 238 is the mass number of the element. The mass number is the sum of the number of neutrons and protons in an element.
Thus, 238 = 92 + neutrons
neutrons = 238 - 92
= 146
Hope this helps!
Answer:
92 protons, 146 neutrons
Explanation:
Uranium will always have the same amount of protons, because that is what defines the element. Uranium has 92 protons, meaning that the rest of the mass of the atom comes from neutrons. 238-92=146 neutrons. Hope this helps!
