Question

What is the excited state electronic configuration of Beryllium?​

Answer 1

Answer:

electron configuration will be 1s22s2. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. This makes it easier to understand and predict how atoms will interact to form chemical bonds.

Answer 2

Explanation:

Beryllium is the fourth element with a total of 4 electrons. In writing the electron configuration for beryllium the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the remaining 2 electrons for Be go in the 2s orbital. Therefore the Be electron configuration will be 1s22s2..
