Which reaction produces two neutrons? 252Cf + 10B 257Lr + ? 241Am + α 243Bk +...
The partially completed nuclear reaction below is an example of a reaction which produces neutrons in older stars: 23^na + alpha rightarrow ___? + n The neutrons can go on to help make still heavier elements in sequences such as: 98^Mo + n rightarrow ___? rightarrow ___? + beta^-
A set of 4 protons and 4 neutrons enter a nuclear reaction. The reaction produces 5 protons and which numbers of neutrons and electrons?
How many neutrons are produced in this fission reaction? n* + 239Pu → 96Sr + 140Ba + ??n
Which of the following explain why the critical mass of 239Pu is significantly smaller than that of 235U when used as a reactor fuel? 239Pu is more massive than 235U235U. 239Pu produces more neutrons per fission. 239Pu is easier to fission by thermal neutrons.
An alpha (α) particle is the nucleus of a 4He atom and consists of 2 neutrons and two protons bound together. Let's take apart an α particle, step by step, looking at the energy required at each step. To do so, we may want to use the following atomic masses: 4He 4.0026 u 2H 2.0141 u 3H 3.01605 u 2H 1.00783 u p 1.00728 u n 1.00867 u e 5.48 × 10-4 u 1)What is the energy required to remove...
The nucleus of 8Be, which consists of 4 protons and 4 neutrons, is very unstable and spontaneously breaks into two alpha particles (helium nuclei, each consisting of 2 protons and 2 neutrons) (a) What is the force between the two alpha particles when they are 4.52 x 10-15 m apart? (b) What is the initial magnitude of the acceleration of the alpha particles due to this force? Note that the mass of an alpha particle is 4.0026 u.
