Which missing item would complete this beta decay reaction?
Karo-lina-s [1.5K]
The question is incomplete. Complete question is attached below:
.................................................................................................................

Correct Answer is : 54 131Xe

Reason: 
Emission of beta particle from radioactive material increases atomic number by one, but atomic mass number donot change.

In present case, the reactant is 53 131 I. When, iodine emits beta particle i.e. electron, it atomic number increases by one. Hence, it gets converted into Xe. Atomic number of Xenon is 54.

Need help calculating atomic mass (see pohoto for more info)
polet [3.4K]

Answer:

28.1

Explanation:

Divide the percentage abundances by 100:

92.2% ÷ 100 = 0.922

4.7% ÷ 100 = 0.047

3.1% ÷ 100 = 0.031

multiply them by their corresponding mass number:

0.922×28 = 25.816

0.047×29 = 1.363

0.031×30 = 0.93

add them all together to get your final answer:

25.816 + 1.363 + 0.93 = 28.109

to one decimal place:

28.1

I hope that helps!!!
