Be (beryllium) has four electrons total: the first orbital, the 1s orbital, has two, which leaves two electrons in the outer shell.
The atomic number of lithium (Li) is 3, and so it has 3 protons in the nucleus. The number of neutrons depends on which isotope of lithium you have. The most common isotope (92.5%) is 7Li with 4 neutrons.A neutral atom of lithium has three electrons in it. Lithium has two electron shells that have electrons in them. The 1s shell has a pair of electrons in it (the maximum), and the 2s shell has one electron in it. Note that this is a neutral atom of lithium, and lithium is reactive. It would like to loan that 2s electron out if it can. It will react with air, either with the oxygen in it or the moisture, if there is any.See the Related Questions below for more information about the particles in the nucleus.
Yes H has 1 e- in 1s shell but when H is treated with more electronegative atom then it loose it's e- n it's nucleus becomes naked due 2 which it becomes very reactive

It is most likely a glitch.

Enrique Iglesias! para todos magazine has already crowned him that and he has the maximum amount of number 1s on the latin charts and he is like a god so obviously its him.
The electron configuration 1s¹ corresponds to the element hydrogen. It indicates that hydrogen has one electron in its first and only energy level (the 1s orbital). Hydrogen is the simplest and most abundant element in the universe, with an atomic number of 1.
