b.equal to one

c.equal to1.2

d.greater than 1.5





ans this question with explaination.

Answer 1

Answer:

option a. less than 1 is correct

Answer 2

● A radioactive nuclide generally disintegrates by α-emission when its N/P ratio is

• Less than 1
• Equal to one
• Equal to 1.2
• Greater than 1.5 ✔✔

● A radioactive nuclide generally disintegrates by α-emission when its N/P ratio is Greater than 1.5.

• Alpha (α) decay is the emission of an α particle from the nucleus. Alpha decay occurs primarily in heavy nuclei (A > 200, Z > 83). Because the loss of an α particle gives a daughter nuclide with a mass number four units smaller and an atomic number two units smaller than those of the parent nuclide, the daughter nuclide has a larger n:p ratio than the parent nuclide. If the parent nuclide undergoing α decay lies below the band of stability, the daughter nuclide will lie closer to the band.
