Full structure of a beryllium? ?

The full structure of beryllium can be described as follows:

- Atomic number: 4
- Atomic mass: 9.0122 g/mol
- Electron configuration: 1s2 2s2
- Number of protons: 4
- Number of neutrons: 5
- Number of electrons: 4

Beryllium is a Group 2 element in the periodic table, also known as an alkaline earth metal. It has a shiny, silver-gray appearance and is relatively lightweight. Beryllium is highly toxic and should be handled with care.

Key Features:

- Beryllium is in Group 2 (alkaline earth metals) and Period 2 of the periodic table.
- It has an atomic number of 4, which means it has 4 electrons.
- The electron configuration indicates that beryllium has a filled outer shell (2 electrons in the 2s orbital), making it a chemically stable and non-reactive element.
- Beryllium is a strong reducing agent, meaning it readily loses electrons.
- It forms ionic bonds with other elements, losing two electrons to achieve a stable configuration of 1s².
