In alpha emission, the ratio of decrease in proton number to the decrease in neutron number is:
Correct answer: B. 1:1
- A. 2:1
- B. 1:1
- C. 1:2
- D. 4:1
Explanation
In alpha decay, a nucleus emits an alpha particle, which consists of two protons and two neutrons. This results in the loss of two protons and two neutrons from the original nucleus.The ratio of decrease in proton number to the decrease in neutron number in alpha decay is 1:1. This is because an alpha particle consists of two protons and two neutrons, so the loss of an alpha particle results in the loss of two protons and two neutrons from the original nucleus. Therefore, the ratio of decrease in proton number to the decrease in neutron number is the same, which is 1:1.
