2024年6月4日 · The electron configuration for Lithium (Li) is 1s^2 2s^1. It has 3 electrons distributed in energy levels.

2017年1月21日 · Lithium, a group 1 element with an electron configuration of 1s22s1, will form a cation ion a chemical reaction. It is so, because as mentioned before it is part of group 1 elements and these tend to lose electrons from other element they react with.

2019年4月8日 · The electron configuration of an element is 1s22s1. To determine the number of valence electrons, we look at the highest energy level, which is indicated by the last number in the electron configuration. In this case, the highest energy level is the 2s level. Therefore, the element has 1 valence electron.

To determine the electron configuration for lithium, let's look at some key information: 1. Atomic Number : Lithium has an atomic number of 3, which means it ha…
