How many electrons must be lost or gained al
WebNov 19, 2024 · Answer: The number of electrons that must be gained or lost by the following atoms to achieve a stable electron configuration is : Barium (Ba) - 2 electrons lost Phosphorus (P)- 3 electrons gained Cesium (Cs) - 1 electron lost Chlorine (Cl) - 1 electron gained Aluminum (Al) - 3 electrons lost Explanation: Web(a) magnesium (Mg) (b) aluminum (Al) (c) bromine (Br) For example, oxygen forms ionic compounds as an anion with -2 charge because it needs to gain two electrons to have the same electron configuration as neon. Gallium, on the other hand, has a +3 charge because it needs to lose three electrons to have the same electron configuration as argon.

WebSo electrons in the first electron shell can only have a value of l=0 since n=1. Electrons in the second electron shell can have a value of l=0 AND 1 since n=2, and so on. The subshell tells us broadly the shape the orbitals which hold the electrons take on and these are represented by the letters s, p, d, and f. WebEither atoms gain enough electrons to have eight electrons in the valence shell and become the appropriately charged anion, or they lose the electrons in their original valence shell. The lower shell, now the valence shell, has eight electrons in …
WebJun 15, 2015 · The explanation is simple: the story is that nice and smooth, when you have to loose one or two electrons. Things in the middle don't just lose 8 electrons or get 5 … WebJan 30, 2024 · The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds. When discussing the octet rule, we do not consider d or f electrons.
WebApr 16, 2024 · Lithium, an alkali metal with three electrons, is also an exception to the octet rule. Lithium tends to lose one electron to take on the electron configuration of the nearest noble gas, helium, leaving it with two valence electrons. There are two ways in which atoms can satisfy the octet rule. WebHow many electrons must be lost by the element Li? number of electrons: Which noble gas electron configuration is attained in this process? xenon krypton radon neon argon heliumNonmetals gain electrons under certain conditions to attain a noble gas electron This problem has been solved!
WebTwo (or more elements) can share electrons so that each attains the electron configuration of the nearest noble gas. The alkali metals will lose an electron to resemble the next lowest noble gas; thus, all the alkali metals form +1 ions. K loses an electron so that it will have the same electron configuration as Ne. Since K loses one electron ...
