What percentage of a radioactive species would be found as daughter material after seven half–lives?

Bond [772]

<span>The relation between number of half-lives and the amount of sample that remained is expressed as: (1/2)^n = x So, given is 7. To find x, we will change the equation with 7: (1/2)^n = x (1/2)^7 = x 0.5^7 = x 0.0078125 = x 0.0078125 x 100% = x x = 0.78125 Therefore, 0.78 % of a radioactive species would be created as daughter material after seven half-lives.</span>

According to the molecular orbital energy-level diagram below, which one of the following statements is not correct about NO, NO

Lubov Fominskaja [6]

None of the statement is not correct about NO, NO+, and NO−.

Explanation:

Those molecules whose all subshells are completely filled are diamagnetic.

Those molecules whose any sub-shell is incomplete is termed paramagnetic.

Let us check the magnetism in all three molecules based on molecular orbital theory and Lewis structure

NO= number of electrons 11

It form N=O having configuration 1s2,2s2,2p6,3s1, it has 1 unpaired electron so it is paramagnetic.
