Webeight electrons occupy the second shell one electron occupies the third shell This electronic structure can be written as 2,8,1 (each comma, or dot, separates one shell from the next). WebLithium has two stable isotopes, Li-6 and Li-7, the latter being 92.5% in nature (hence relative atomic mass of natural lithium of 6.94). Nuclear industry use: Li-7. Lithium-7 has two important uses in nuclear power due to its relative transparency to neutrons. As hydroxide it is necessary in small quantities for safe operation in pressurised ...

3.4: Atomic Mass and Atomic Number - Chemistry LibreTexts

WebWhen forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge. We can use this method to predict the charges of ions in ionic compounds.
