For example, all the metals, be it hydrogen, lithium, sodium and so on, present in column 1 have valency +1.
Electron configuration - Wikipedia
Web28 mrt. 2024 · Hydrogen and helium have only one electron shell. The first shell has only one s orbital and no p orbital, so it holds only two electrons. Therefore, these elements are most stable when they have two electrons. You will occasionally see hydrogen with no electrons, but H + is much less stable than hydrogen with one or two electrons. WebThe helium atom has only the 1s orbital in its only shell, and it is completely filled with 2 electrons. Its electronic configuration is 1s2. Therefore, helium and the other inert gases with complete octets normally do not take part in chemical reactions. They are considered as zero-valent elements. 9 1 Joseph Hall interplan chicago
