WebMar 3, 2024 · Beryllium has 4 electrons in neutral atom. Lowest energy levels are filled first. So firstly 1s2 (ist shell now filled) That leaves 2 left over. So they go into the 2nd shell and the 2s orbital. Therefore electron configuaration is 1s2 2s2. That's it, no electrons left over to put into 2p. Share Improve this answer Follow

Beryllium (Be) - Periodic Table (Element Information

WebFor example, elements such as boron or beryllium often form compounds in which the central atom is surrounded by fewer than eight electrons (e.g., BF₃ or BeH₂). In contrast, many elements in the third-row and beyond have been observed to exceed the octet rule, forming compounds in which the central atom is surrounded by more than eight ...
