Question

Complete the following nuclear bombardment equation by filling in the nuclear symbol for the missing species.

Answer 1

Answer:

Strontium $94_{38}$Sr

Explanation:

By the law of mass conversion the nuclear mass remains constant in a reaction which means initial mass and atoic number will be equal to final atomic number and atomic mass respectively.

²³⁵₉₂U + ¹₀n → ? + ¹³⁹₅₄Xe + 3 ¹₀n

Here atomic mass =

235 + 1 = A + 139+3 ( A -= atomic mass of ?)

A = 236 - 142

A = 94

And, atomic number would be =

92 = B + 54

B = 92 - 54

B = 38

So, the atomic number of ? will be 38 and atomic mass will be = 94

The element with 38 atomic number is = Strontium $94_{38}$Sr
