Web5 apr. 2024 · Lithium, which exhibits no natural radioactivity, has two isotopes of mass number 6 (92.5 percent) and 7 (7.5 percent). The lithium-7 / lithium-6 ratio is between 12 and 13. WebThe s-subshell can fit 2 electrons, p-subshell can fit a maximum of 6 electrons, d-subshell can fit a maximum of 10 electrons, and f-subshell can fit a maximum of 14 electrons. The first shell has only an s orbital, so its called as 1s. Since it can have either one or two electrons, its called as 1 s 1 and 1 s 2 respectively.
Lithium - Element information, properties and uses Periodic Table
WebAnd this is explained if we look at fluorine's valence shell (the second shell) electron configuration: 2s^ (2)2p^ (5). The second electron shell holds a maximum of 8 electrons and 8 electron would be considered a filled valence shell and would therefore be stable and unreactive. But fluorine has 7 valence electrons, 1 away from being filled. WebWe know that the atomic number of lithium is 3 and the atomic mass number is about 7(6.938). Neutron (n) = 7 – 3 = 4. Therefore, the number of neutrons in lithium is 4. What … how to start sdmo generator s4500
