WebThe electron dot diagram shows the arrangement of dots without identifying the element. Which element's symbol could replace the question mark in the diagram? tellurium (Te) Helium (He) and neon (Ne) are elements in Group 8A of the periodic table. How do the electron dot diagrams of these elements compare? WebThis can be explained as an electron configuration and is designated as 1s1 (1 representing the electron shell, and s the subshell). The superscript 1 indicates one electron within the 1s orbital. Helium has two electrons, both in the first energy shell so is designated as 1s2. All of the space in the first energy shell is now filled.

Web1 day ago · However, helium was surprisingly placed among alkaline earth metals. This shift can be justified by the outer electron structure of helium, which, like the other members of the alkaline earth group, has two such electrons. However, from a chemical point of view, helium, like noble gases, is the least reactive of all elements in the periodic table. WebExplanation: Helium only has 2 electrons and therefore it has a configuration of 1s2. 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.

WebHelium is composed of two electrons in atomic orbitals surrounding a nucleus containing two protons and (usually) two neutrons. As in Newtonian mechanics, no system that consists of more than two particles can be solved with an exact analytical mathematical approach (see 3-body problem) and helium is no exception.
