Lewis structure for ca

In almost all cases, chemical bonds are formed by interactions of valence electrons in atoms. To facilitate our understanding of how valence electrons interact, a simple way of representing those valence electrons would be useful. A Lewis electron dot symbol or electron dot diagram or a Lewis diagram or a Lewis structure is a representation of the valence electrons of an atom that uses dots around the symbol of the element. The number of dots equals the number of valence electrons in the atom. These dots are arranged to the right and left and above and below the symbol, with no more than two dots on a side. It does not matter what order the positions are used. Figure 1. Lewis symbols illustrating the number of valence electrons for each element in the third period of the periodic table. Lewis symbols can also be used to illustrate the formation of cations from atoms, as shown here for sodium and calcium: Likewise, they can be used to show the formation of anions from atoms, as shown below for chlorine and sulfur: Figure 2 demonstrates the use of Lewis symbols to show the transfer of electrons during the formation of ionic compounds. Figure 2. Cations are formed when atoms lose electrons, represented by fewer Lewis dots, whereas anions are formed by atoms gaining electrons. The total number of electrons does not change. The valence electron configuration for aluminum is 3 s 2 3 p 1. So it would have three dots around the symbol for aluminum, two of them paired to represent the 3 s electrons or three single dots around the atom :.

In all cases, these bonds involve the sharing or transfer of valence shell electrons between atoms. In this section, we will explore the typical method for depicting valence shell electrons and chemical bonds, namely Lewis symbols and Lewis structures. We use Lewis symbols to describe valence electron configurations of atoms and monatomic ions. A Lewis symbol consists of an elemental symbol surrounded by one dot for each of its valence electrons:.

Lewis symbols can also be used to illustrate the formation of cations from atoms, as shown here for sodium and calcium:.

The Calcium Lewis dot structure is very simple and easy to represent. This article illustrates the calcium Lewis dot structure and its combination with other atoms to form stable compounds. Because it is in group 2 it has only 2 valence electrons.
