The heat released : -110560.632 J
<h3>Further explanation</h3>
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
<h3>Known</h3>
m =465 g
c water = 4.186 J/gram °C
∆T = temperature difference = 18.2 - 75 = - 56.8 °C
Then the heat :

Notice the subscript went from 83 to 84 and the 214 stayed the same that means it was beta decay.

I answered this already :)
Answer:
lose or share electrons in such a way that the outer shells become chemically complete
Explanation:
Most interactions among atoms take place in the outermost shell of each atom. The number of each electron in this shell determines how an atom combines with other atoms to form compounds. When atoms combine they gain, lose or share electrons in such a way that the outer shells become chemically complete.
