Which electron configuration represents the
Pachacha [2.7K]

This problem is asking for the electron configuration of an excited atom of gallium, which according to the group it is, its excited state will theoretically be Ga³⁺, since it is a metal and loses three or less electrons, that is why it turns out positive. After writing the electron configuration, we realize the answer must be 2-8-17-4 according to the following:

<h3>Electron configurations:</h3><h3 />

In chemistry, electron configurations allow us arrange the electrons of an element according to specific energy levels and orbitals. In such a case, it turns out possible to write Gallium's electron configuration in its ground-state as follows:

1s^22s^22p^63s^23p^64s^23d^{10}4p^1

However, since the given choices do not match with a charge of 3+ as formerly explained, we assume this gallium atom will be excited to 1+, due to the fact that the third energy level comprising 18 electrons, will give one to the fourth energy level, turning out in an electron configuration of:

1s^22s^22p^63s^23p^64s^23d^{9}4p^2

Which matches with 2-8-17-4 as two electrons are present in the first energy level, eight in the second one, now seventeen in the third one and four in the fourth one.
