Question

l Se Periodic Table Se Hint The type of nuclear decay an unstable nucleus will undergo depends on its ratio of neutrons to protons. The radioisotope cobalt-65 has a ratio of neutrons to protons of 1.41, which is too high for a nucleus of this size. What nuclear changes could reduce this ratio? Choose one or more a decrease in atomic number an increase in the number of protons conversion of one or more neutrons to protons removing electrons from the valence shell conversion of one or more protons to electrons Part 2 (1 point) 9 See Hint Which particle could be emitted from the nucleus of cobalt-65 to decrease the ratio of neutrons to protons? Choose one: +1 3OF SOLIEST?nlus rvun.ET.n

Explanation / Answer

Part-A

n/p ratio =1.41

to decrease the n/p ratio ., the number of neutrons are convert to protons.

number of neutrons are converts to protons , means nuetrons are decreses and the same time number of protons are increaes.

The answer is C

Part-2

0 n1 ----------- 1P1   + -1 b0   

In the conversion of neutron to protons by the emission of Beta p[artcle.

The answer is D
