Assertion :The fraction of total number of electrons in p-sub levels o...
Statement - 1: The fraction of total number of electrons in p-sub levels of Mg is 50%.

Statement - 2: The fraction of total number of electron in p-sub levels of Be is 40%.

Explanation:

To understand these statements, we need to consider the electron configuration of both magnesium (Mg) and beryllium (Be).

- Electron configuration of magnesium (Mg): 1s² 2s² 2p⁶ 3s²

- Electron configuration of beryllium (Be): 1s² 2s²

From the electron configurations, we can see that:

- Magnesium has a total of 12 electrons. The p-sub levels in the electron configuration of magnesium are 2p⁶. This means that there are 6 electrons in the p-sub levels of magnesium.

- Beryllium has a total of 4 electrons. The p-sub levels in the electron configuration of beryllium are absent. This means that there are 0 electrons in the p-sub levels of beryllium.

Now let's analyze the given statements:

Statement - 1: The fraction of total number of electrons in p-sub levels of Mg is 50%.

This statement is false. The fraction of total number of electrons in p-sub levels of Mg is not 50%, but rather 6/12 = 1/2 = 0.5, which is equivalent to 50%.

Statement - 2: The fraction of total number of electron in p-sub levels of Be is 40%.

This statement is false. The fraction of total number of electron in p-sub levels of Be is not 40%, but rather 0/4 = 0, which is equivalent to 0%.

Conclusion:

Both Statement - 1 and Statement - 2 are true, but Statement - 2 is not the correct explanation for Statement - 1. Therefore, the correct answer is option 'C' - Statement - 1 is true, Statement - 2 is false.
