Furthermore, you can also use the periodic table to determine the valency of calcium. Both of the rules are helpful in analyzing the valency of calcium. As per the duplet rule, the atom can have a maximum of 2 electrons in the outer shell. As per the octet rule, the atom can have a maximum of 8 electrons in the outer shell. There are two rules to find out the valence electrons of calcium such as the duplet rule and the octet rule. Rules to Determine the Valence Electrons of Calcium The feature of valency is one of the most significant features of the chemical element. Moreover, it can be claimed that calcium gets stable by getting or losing 2 electrons. 2 valence electrons depict that calcium can get or lose 2 electrons. It means that the valency of calcium is 2+. In addition, it varies because of variations in the reduction and oxidation conditions.Ĭalcium has 2+ valence electrons. Valency changes and does not remain the same all the time. Valency represents that how many electrons the atom can gain or lose in bond formatting to get stability. Further, they are exact in number, and they cannot be more or less in number. The valence electrons represent that how many electrons are available in the outer shell of the atom. The dot diagram helps in analysing the atoms and molecules’ structure for valence electrons.ĭot diagram of calcium valence electrons The Valence Electrons and Valency of Calcium Lewis dot diagram is the easy way to find out the valence electrons of calcium. It reacts with the element having 6 valence electrons that need to get two electrons. Having 2 valence electrons, calcium is choir reactive. Calcium in the Periodic TableĬalcium is available in group 2 of the periodic table. Moreover, it is helpful in digestion, muscles health, and circulation of the blood. Calcium carbonate is the significant compound of calcium that you can get from limestone. Some chemical elements occur in the body, and calcium is one of those chemical elements. So it is an important particle of the human body. Calcium is available in human beings as well. It is amongst the top 3 metals that are easily available on the surface of the earth. You can easily find calcium in the maximum quantity in this world. In addition, the atomic number of calcium is 20. Valence electrons of calcium Characteristics of CalciumĬalcium is a reactive element. Henceforth it represents that why all the elements have similar chemical characteristics in the same group. All the elements have similar valence electrons in the periodic table. Also, the valence electrons increase from one element in groups 1 to 2 and 13 to 18. The periodic table shows the valence electrons of an atom along with its position. Therefore, there cannot be more than eight dots of an atom. Atom can have only eight valence electrons up to the maximum level. Additionally, the dots in chemical symbols are the valence electrons. Such simple diagrams are known as electron dot diagrams. So we make simple diagrams to show the atoms with their valence electrons.
