Thorium-232 decays by a 10-step series, ultimately yielding lead-208. How many α particles and how many β particles are emitted?

Identify each of the following as alpha decay, beta decay, positron emission, or gamma emission: (5.1, 5.2)a. ¹²⁷₅₅Cs → ¹²⁷₅₄Xe + ⁰₊₁e

a. What are the products in the fission of uranium-235 that make possible a nuclear chain reaction? (5.6)

Where does fusion occur naturally? (5.6)

All the elements beyond uranium, the transuranium elements, have been prepared by bombardment and are not naturally occurring elements. The first transuranium element neptunium, Np, was prepared by bombarding U-238 with neutrons to form a neptunium atom and a beta particle. Complete the following equation: (5.2)¹₀n + ²³⁸₉₂U →? + ?

Californium-246 is formed by bombardment of uranium-238 atoms. If four neutrons are formed as by-products, what particle is used for the bombardment?
