WebJan 30, 2024 · Argon has a total of 8 electrons (bolded in red), which satisfies the Octet Rule. Phosphorus needs to gain 3 electrons to fulfill the Octet Rule. It wants to be like Argon who has a full outer valence shell. … WebIn writing the electron configuration for Argon the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Argon go in the 2s orbital. …

WebBohr diagrams indicate how many electrons fill each principal shell. Group 18 elements (helium, neon, and argon) have a full outer, or valence, shell. A full valence shell is the most stable electron configuration. Elements in other groups have partially filled valence shells and gain or lose electrons to achieve a stable electron configuration. 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. ... to have an electron configuration like argon. So if it loses two electrons it has a positive two ... chevy small work vans

WebGroup 18 elements (helium, neon, and argon are shown in Figure 2) have a full outer, or valence, shell. A full valence shell is the most stable electron configuration. Elements in … WebOct 5, 2014 · Oct 5, 2014 Calcium atoms will lose two electrons in order to achieve the noble gas configuration of argon. A neutral calcium atom has 20 electrons, while a calcium atom that has lost two electrons will have 18 electrons, and a neutral argon atom also has 18 electrons. A neutral calcium atom, 20Ca, has 20 electrons with an WebJul 25, 2024 · In general, it’s easy to gain or lose electrons but very difficult to gain or lose protons. So atoms become ions by gaining or losing electrons. And ions that have a positive charge are called cations. The progression goes like this: The sodium ion shown above is formed from the loss of one electron. Because it lost an electron, it has more ... goodwill locations in illinois
