Question

Strontium decays by beta decay part of the nuclear equation is shown below fill in the blank with a number? 90/38Sr -> 0/-1e 90/blankY

Answer 1

the blank is 39

Explanation: a p e x

Answer 2

Answer : The chemical equation for the beta decay process of
`_(38)^(90)\textrm{Sr}` follows:

`_(38)^(90)\textrm{Sr}\rightarrow _(39)^(90)\textrm{Y}+_(-1)^0\beta`

Explanation :

Beta decay : It is defined as the process in which beta particle is emitted. In this process, a neutron gets converted to a proton and an electron.

The released beta particle is also known as electron.

The beta decay reaction is:

`_Z^A\textrm{X}\rightarrow _(Z+1)^A\textrm{Y}+_(-1)^0\beta`

The chemical equation for the beta decay process of
`_(38)^(90)\textrm{Sr}` follows:

`_(38)^(90)\textrm{Sr}\rightarrow _(39)^(90)\textrm{Y}+_(-1)^0\beta`
