19. BERYLLIUM

19



BERYLLIUM





CHAPTER 19 - BERYLLIUM (4 Pages) - is a small chapter. But it explains the reason for the steep increase in the melting point from lithium to beryllium, and then beryllium to carbon. 
It explains why Be, (1s22s2), is not remaining as a mono-atomic gas just like He(1s2). 

It also explains the greater reactivity of Be compared to He, which has an electronic configuration similar to that of Be.
