Explanation:
Your unbalanced nuclear equation is:
The main point to remember in balancing nuclear equations is that the sums of the superscripts and the subscripts must be the same on each side of the equation.
Then
84 = x + 2, so x = 84 - 2 = 82
210 = y + 4, so y = 210 - 4 = 206
Element 82 is lead, so the nuclear equation becomes
Answer:
Average atomic mass of potassium based on these relative abundances
Explanation:
The atomic mass of this element will be equal to the sum of product of its three isotopic masses and its fractional abundance
For isotope I -
Mass of Potassium-39 amu
Fractional abundance of Potassium-39 %
Mass of Potassium-40 amu
Fractional abundance of Potassium-40 %
Mass of Potassium-41 amu
Fractional abundance of Potassium-41 %
Average atomic mass of potassium based on these relative abundances
