hope this helped!
Electron configuration is applied to chemical elements.
Electronic configuration of calcium chloride
Lined canals are canals which are manmade and they have boundaries across them.Whereas, unlined canals are canals which consist of beds and banks made from natural soil. They are not provided with a lining
The electronic configuration of Calcium is 2-8-8-2, therefore the valency of Calcium is +2.
The electron configuration of the chloride ion is: [Ne] 1s2.2s2.2p6.3s2.3p6.
Considering the normal calcium ion Ca2+ it has the same electronic configuration as the noble gas Argon.
[Ne] 3s2 3p5 is the electronic configuration for neutral Chlorine. Its -1 ion, however is: [Ne] 3s2 3p6 or [Ar].
The electronic configuration of calcium is 2, 8, 8, 2 and the fourth energy level has 2 electrons.
The electronic configuration of calcium in calcium hydroxide is the configuration of a calcium +2 ion, which is the same as the configuration of the preceding noble gas, argon.
The electronic configuration of Calcium is 2-8-8-2, therefore the valency of Calcium is +2.
The electron configuration of the chloride ion is: [Ne] 1s2.2s2.2p6.3s2.3p6.
calcium has the complete electronic configuration: 2, 8, 8 2 and hence has 2 valence electrons.
Considering the normal calcium ion Ca2+ it has the same electronic configuration as the noble gas Argon.
Calcium
The element calcium (atomic number 20) has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 or in noble gas form : [Ar] 4s2
[Ne] 3s2 3p5 is the electronic configuration for neutral Chlorine. Its -1 ion, however is: [Ne] 3s2 3p6 or [Ar].
The element chlorine does not have noble gas configuration. But chloride ion formed (when chlorine accepts an electron) has noble gas configuration of argon.
The difference of calcium chloride and fused calcium chloride is the bond acting on their molecules. The fused calcium chloride is fused while the calcium chloride is not fused.
Calcium atoms have the electronic configuration 2,8,8,2 so they react by losing 2 electrons. Chlorine is 2,8,7 so picks up one electron. Therefore each calcium ion is formed in conjunction with two chloride ions. The calcium ions are positively charged, and the chlorides are negative so the substance is held together by electrostatic attraction. This process is called ionic bonding.
The electronic configuration of calcium is 2, 8, 8, 2 and the fourth energy level has 2 electrons.
