Question

Which nucleus completes the following equation?
39 17 CI-> 0 -1 e+?

Answer 1

Answer is below

Step-by-step explanation:

39 18 Ar

Answer 2

`_(18)^(39) } Ar`

Step-by-step explanation:

The given equation shows the disintegration of an unstable isotope of chlorine to beta particle and Argon nucleus. The nucleus undergoes the emission of a beta particle to form a more stable nucleus of Argon.

`_(17) ^(39) Cl` ⇒
`_(-1)^(0) e` +
`_(18)^(39) } Ar`

Argon is a stable gas and is found in the group 8 on the periodic table of elements.
