Analysis

1. Alpha Particles
a. What is the mass number of an alpha particle?


b. What kind of charge does an alpha particle have?


c. What is the identity of an alpha particle? (Hint: What atomic symbol is used?)


d. Write the balanced equation for the alpha decay that is below the “Show Equation.” Label the parent, daughter, and alpha particle.

Please help

Answer 1

Below.

Step-by-step explanation:

1.

a. An alpha particle has 2 protons and 2 neutrons ( a helium nucleus).

b. The charge on an alpha particle is 2+.

c. Atomic symbol used is α or He2+.

d. (no equation shown).

Americanum 241 decays to Neptunium 237 with the loss of 1 alpha particle

Am 241 = Np 237 + Ne2+

- note the atomic mass is 4 less under the decay.
