For this question, CHOOSE THE CORRECT ANSWER, then explain your reasoning in the RATIONALE section below: Alpha,
Beta-plus, Beta-minus and Gamma decay are all different forms of radio-Active decay. A certain radio-isotope emits ONE
alpha particle, and its products then emit TWO beta-minus particles in succession. The atomic number of the final resulting
nucleus will now change (as compared to your starting nucleus) by
O A. zero
O B. minus 1
OC. minus 2
O D. minus 3
Compute for the following. Round your answers into to 2 significant figures.
1. What is the charge of an object that has 3,000,000 excess electrons?
2. What is the charge of an object that has 5,000,000 electron deficits?
