WebDec 15, 2024 · Well, in general, people will refer to the octet rule. For our second, third, fourth, fifth, and on and on shells, you're full when you have eight electrons. Eight electrons. The major exception to the octet rule is the first shell, where it is full with two electrons. So helium, even though it only has two electrons, is very, very, very stable. WebHelium only has 2 electrons and therefore it has a configuration of 1s 2. Because the 1s orbital is full with 2 electrons and any additional electrons would go in a new energy level. The electron configuration for Helium shows a full outer shell and is Helium is therefore called a Nobel Gas. This means it will not react with other atoms.

Webthe ions have the electronic structure of a noble gas (group 0 element), with a full outer shell For elements in groups 1, 2 and 3, the number of electrons lost is the same as the group... WebThe noble gases are the elements at the far right-hand column of the periodic table: helium, neon, argon, xenon, and radon. Because of the group they belong to, they each have a full valence shell or level. In the case of helium, a full valence shell has two electrons, and in the remaining noble gases, eight electrons make up a full valence shell.

The next atom is the alkali metal lithium with an … WebHelium atoms have two electrons in their outer shell and the other noble gases have eight electrons in their outer shell. This is the maximum number that will ‘fit’ each shell, making the atoms stable. The current model depicts the electrons moving in space around the nucleus in a more cloud-like formation and not set in fixed shells.

WebNov 4, 2024 · Remember that an element's electron cloud will become more stable by filling, emptying, or half-filling the shell. Also, shells don't stack neatly one on top of another, so don't always assume an element's valence is determined by the number of electrons in its outer shell.
