Question

Which nucleus completes the following equation?

Answer 1

Option D. ⁸⁵₃₆Kr

Step-by-step explanation:

⁸⁵₃₅Br —> ⁰₋₁e + ?

Let ⁿₘZ represent the unknown.

Thus, the equation becomes:

⁸⁵₃₅Br —> ⁰₋₁e + ⁿₘZ

Next, we shall determine n, m and Z as follow:

85 = 0 + n

85 = n

Thus,

n = 85

35 = –1 + m

Collect like terms

35 + 1 = m

36 = m

Thus,

m = 36

ⁿₘZ => ⁸⁵₃₆Z = > ⁸⁵₃₆Kr

Thus, the equation:

⁸⁵₃₅Br —> ⁰₋₁e + ⁿₘZ

Becomes:

⁸⁵₃₅Br —> ⁰₋₁e + ⁸⁵₃₆Kr
