Determine the value of x from the nuclear reaction below,
22286Rn → x88Ra + 2β + energy
220
222
224
226
228
Correct answer is B
The equation above is Beta-decay:
where β is an electron → 0−1e
2β in the equation = 0−1e + 0−1e → 0−2e
22286Rn → x88Ra + 0−2e + energy
where x88Ra + 0−2e → 22286Rn
: x = 222 for element Radon [ 22288Ra
