Bi undergoes four decay reactions: α, β, β, α. step 1. undergoes α decay to give in the second step, tl-210 undergoes β decay. what is the product of this step? symbol = mass number = atomic number =

Pb-210 that lead-210 is the product of second step.

Explanation:

Alpha decay : When a larger nuclei decays into smaller nuclei by releasing alpha particle. In this process, the mass number and atomic number is reduced by 4 and 2 units respectively.

General representation of alpha decay :

Beta decay : In this process, a neutron is converted into a proton and an electron. In this decay, the atomic number is increased by 1 unit.

General representation of beta decay :

Step 1. Bi undergoes α decay;

81 = Z-2

Z = 83

210 = A - 4

A = 214

Step 2: Tl-210 undergoes β decay:

Pb-210 that lead-210 is the product of second step.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
