Answer 2

Electron Configuration of Beryllium Atom

The electron configuration of an atom describes the distribution of electrons in its energy levels or orbitals. Beryllium (Be) is a chemical element with atomic number 4, which means it has 4 electrons. The electron configuration of a beryllium atom can be represented as 1s^2 2s^2.

This means that the first energy level (n=1) contains 2 electrons in the 1s orbital, and the second energy level (n=2) contains 2 electrons in the 2s orbital.

Electron Configuration of Beryllium Ion

An ion is an atom or a molecule that has gained or lost electrons, resulting in a net positive or negative charge. Beryllium can form a cation (positive ion) by losing its two valence electrons. The electron configuration of a beryllium ion (Be^2+) can be represented as 1s^2.

In the case of the beryllium ion, it has lost its two valence electrons from the 2s orbital, leaving behind the filled 1s orbital.

Please note that the electron configuration of an ion is different from that of the neutral atom because the ion has a different number of electrons.

I hope this helps! Let me know if you have any further questions.
