What happens when calcium reacts with chlorine electrons?
The calcium atom loses two electrons, and each chlorine atom gains one electron, to form a full outer shell of electrons. The electrostatic force of attraction between the oppositely charged ions forms an ionic bond, resulting in the formation of calcium chloride, CaCl2.

How does an atom of calcium react with two chlorine atoms?
Point out that the calcium loses two electrons, becoming a +2 ion. Each of the two chlorine atoms gains one of these electrons, making them each a −1 ion. Help students realize that 1 calcium ion bonds with 2 chloride ions to form calcium chloride (CaCl2), which is neutral. Some atoms gain or lose more than 1 electron.

What is the chemical equation when calcium reacts with chlorine?
Answer and Explanation: The reaction between calcium (symbol Ca ) and diatomic chlorine gas Cl2 C l 2 to give calcium chloride (CaCl2 C a C l 2 ) is shown below: Ca(s)+Cl2(g)→CaCl2(s) C a ( s ) + C l 2 ( g ) → C a C l 2 ( s ) .

What happen when calcium is done with water?
When calcium Ca reacts with water H 2 O , calcium hydroxide Ca ( OH ) 2 is formed along with the liberation of hydrogen gas H 2 . The bubbles of hydrogen gas get stick to the surface of calcium. The reaction is less violent in nature.

Is mixing calcium and water a chemical change?
The dissolving of calcium chloride and baking soda in water are physical changes even though they release or absorb energy. (The solids could be reclaimed if the water were evaporated.) The formation of calcium carbonate, carbon dioxide and carbonic acid are chemical changes.

Does calcium lose all its electrons after transferring them to chlorine?
Point out that the calcium loses two electrons, becoming a +2 ion. Each of the two chlorine atoms gains one of these electrons, making them each a −1 ion. Help students realize that 1 calcium ion bonds with 2 chloride ions to form calcium chloride (CaCl2), which is neutral. Some atoms gain or lose more than 1 electron.

How many electrons does calcium give to chlorine?
Calcium donates its two extra electrons to chlorine, and the resulting positive and negative charges on the atoms bind them together in an ionic bond.
