Anion is an atom which has more electrons than the protons and therefore has negative charge (for example Cl-). 2 Why does the last shell have 8 electrons? How can we avoid the occurrence of weld porosity? Lewis structures help us to track the valence electrons and predict the types of bond.

Inside the dense nucleus, are protons and neutrons (Doc. Valence electrons are the electrons that are shared between atoms which are covalently bonded to each other. 2 How does the outermost electron of a covalent bond move or orbits? This model said that chemical bonds form when the hook on one atom connects with the eye on another atom. The first reason is that the alkali metals have a larger atomic size than the nonmetals, so they have more trouble attracting electrons. Why does the last shell have 8 electrons? Why are electrons important to atoms? An octet can be achieved by sharing, gaining or losing electrons. The atomic number of shell structure of Nuclei are Z= 2,8,20,28,50,82,126 then on. From the Bohr-Bury scheme, we find out the outermost shell of an atom can accommodate a maximum of 8 electrons and thus, it was observed that the elements, having a completely filled outermost shell (meaning zero valency) show little chemical activity. The second energy level can accomodate up to 8 electrons. What are the electrons in the outer energy level known as? Elements that have a full outer shell are inert in that they do not react with other elements to form compounds. 1 What is the importance of valence electrons?
