<u>Answer:</u> The number of protons and electrons in the given ion are 8, 10 respectively.

<u>Explanation:</u>

Atomic number is defined as the number of protons or electrons that are present in a neutral atom.

Atomic number = number of protons = number of electrons

For the given representation of ion, which is:  O^{2-}

We are given:

Atomic number = Number of protons = 8

Charge on the ion = -2

Number of electrons = Number of protons - charge = 8 - (-2) = 10

Hence, the number of protons and electrons in the given ion are 8, 10 respectively.

Troyanec [42]

Yo sup??

Let the percentage of K-39 be x

then the percentage of K-40 is 100-(x+0.01)

We know that the net weight should be 39.5. Therefore we can say

(39*x+40*(100-(x+0.01))+38*0.01)/100=39.5  

(since we are taking it in percent)

39*x+40*(100-(x+0.01))+38*0.01=3950

39x+4000-40x-0.4+0.38=3950

2x=49.98

x=24.99

=25 (approx)

Therefore K-39 is 25% in nature and K-40 is 75% in nature.

Hope this helps.
