Which is the missing value that will balance the equation?

Answer 1

You posted incomplete question. I saw a similar question somewhere.

● Answer- +1.

● Explaination -

We have the nuclear reaction-

222/86 Rn ---> 218/84 Po + x 4/2 He

In the reaction total protons and neutrons must remain constant.

LHS Protons = 86

RHS Protons = 84 + 2x

But we know,

LHS protons = RHS protons

86 = 84 + 2x

x = 1

Thus missing value must be +1.

Hope this us helpful...
