Question

Reasons an isotope may be unstable include all of these EXCEPT:


Select one:


a. not enough energy

b. too many protons

c. too many neutrons

d. too many nucleons

Answer 1

let me guess: an isotope would NOT be unstable if it has "not enough energy". so choice a should be except-ed.

Answer 2

so the answer is A

Answer 3

yes. that's my guess.

Answer 4

It was right Thanks..

Answer 5

let me explain:

too many protons could cause positron emission...

Answer 6

too many neutrons could cause beta emission.

Answer 7

too many nucleons (like nuclei with atomic number greater than 84 (Po)), it tends to undergo alpha emission.

all this according to chemistry: the central science, woo!
