WebAug 21, 2024 · Since aluminum's atomic number is thirteen, it has thirteen electrons. You then split the electrons between the different orbitals. Aluminum's first two electrons fall … WebAn aluminum atom has two electrons in its first shell, eight electrons in its second shell, and three electrons in its third (valence) shell. The second shell has an octet, while the valence shell has 3 electrons. An aluminum atom can achieve octet by losing the 3 valence electrons. (Losing 3 electrons is easier than gaining 5.)
Counting valence electrons for main group elements
WebHence it gains 2 electrons and forms a negative ion. C. Can a stable compound be made from these two atoms? Explain why or why not. ... Mg 1+ F 1-MgF D. Aluminum and … WebDec 15, 2024 · When 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.
