How many electron does lithium have
WebJan 30, 2024 · Lithium's outer electron is in the second level, and only has the 1s 2 electrons to screen it. The 2s 1 electron feels the pull of 3 protons screened by 2 electrons - a net pull from the center of 1+. The sodium's outer electron is in the third level, and is screened from the 11 protons in the nucleus by a total of 10 inner electrons. WebDec 6, 2024 · The lithium atom has a total of 3 electrons, so we have to put 3 electrons in orbitals. The first two electrons will go in the 1s orbital as S orbital can hold a maximum of two electrons only. The remaining one will go in 2s orbital. Now we have,
