Answer: The element E is Krypton (Kr).

Explanation:

In a nuclear reaction, the total mass and total atomic number remains the same.

The given nuclear reaction follows:

$_{35}^{75}\textrm{Br}\rightarrow ^{A}_{Z}\textrm{X}+^0_{-1}\textrm{e}$

Total mass on reactant side = total mass on product side

75 = A + 0

A = 75

Total atomic number on reactant side = total atomic number on product side

35 = Z + (-1)

Z = 36

The isotopic symbol of element E is $_{36}^{75}\textrm{Kr}$

Hence, the element E is Krypton (Kr).
