Chlorine reacts readily with calcium. Calcium donates two electrons to this ionic bond and chlorine accepts one electron from calcium into its valance shell, so you need two chlorines to react with calcium.

Is Ca the most active element?
No, calcium (Ca) is not the most active element. The most active elements are typically found in Group 1 of the periodic table, such as sodium (Na) and potassium (K), which readily react with water and air.
What chemical element is 1s22s22p63s23p64s2?
This chemical element is calcium (Ca).
The element that forms a 2 plus ion with the same electronic configuration as Ar?
The element that forms a 2+ ion with the same electronic configuration as Ar is Calcium (Ca). When Calcium loses two electrons, it attains the same electronic configuration as argon by having a full outer shell of electrons.
What element in the table of element is ca?
Calcium.
Does the Ca plus 2 ion have more electrons than the Ca atom?
No, the calcium ion Ca+2 has fewer electrons than the neutral calcium atom. The calcium atom has 20 electrons, while the Ca+2 ion has 18 electrons because it has lost two electrons to become positively charged.
Which metal will react spontaneously with water?
Sodium is a metal that will react spontaneously with water, producing sodium hydroxide and hydrogen gas. This reaction is highly exothermic and can be violent, often resulting in the production of heat and flames.
Is CaCl2 polyatomic ion?
No, CaCl2 is not a polyatomic ion. It is a compound made up of two different elements – calcium (Ca) and chlorine (Cl).
Is Ca(NO3)2 an ionic or covalent compound?
Ca(NO3)2 is an ionic compound. The calcium ion (Ca2+) is a metal, and the nitrate ion (NO3-) is a polyatomic ion with a charge. Ionic compounds form when metals react with nonmetals to transfer electrons and create a bond.
What is the symbol for the ion Ca?
The symbol for the calcium ion is Ca^2+.
Which element would react most like calcium (ca)?
Strontium (Sr) would react most like calcium (Ca) because they are both in the same group (Group 2) of the periodic table and share similar chemical properties.
What is the formula for calcium ion?
The formula for a calcium ion is Ca2+. This represents a calcium atom that has lost two electrons, resulting in a 2+ charge.
Aqueous hypochlorous acid and aqueous calcium hydroxide react?
Aqueous hypochlorous acid and aqueous calcium hydroxide react to produce aqueous calcium hypochlorite and water. This is a double displacement reaction where the hydrogen ion from the acid is replaced by the calcium ion, forming a new salt.
Does an alkaline earth metal element form an ion with a charge of -1?
Alkaline earth metals form cations withe the electrical charge +2.As an exceptional curiosity exist the ion Ca-.
WHAT IS THE DIFFERENCE BETWEEN CA AND CA2 plus?
Ca refers to calcium, which is a chemical element with the atomic number 20. Ca2+ refers to a calcium ion that has lost two electrons, resulting in a 2+ charge. The main difference is that Ca represents the neutral form of calcium, while Ca2+ represents the positively charged ion form.
Is Ca the most active element?
No, calcium (Ca) is not the most active element. The most active elements are typically found in Group 1 of the periodic table, such as sodium (Na) and potassium (K), which readily react with water and air.
Is Ca plus 2 an ion?
No, "Ca plus 2" is not correct notation for an ion. The correct notation would be Ca^2+, which represents a calcium ion with a 2+ charge due to the loss of two electrons.
Ar4s2 belongs to which element?
Ar4s2 belongs to the element calcium (Ca).
