There are three atoms in CaCl2 (calcium chloride) - one calcium atom and two chlorine atoms. It might be argued that there are ions inside the molecule instead of atoms. In that case there is one calcium ion and two chlorine ions.
Ca + Cl2 --> CaCl2 or Ca2+ + 2 Cl- --> CaCl2
calcium and chlorine combines to produce CalciumChloride (CaCl2) as chlorine needs 1 electron to complete its octate... and calcium needs to lose 2 electrons to stablized.. therefore 2 atoms of chlorine react with a single atom of calcium to stablized. Atomic numbers are as follow : Calcium 20 Chlorine 17
calcium + chlorine yields calcium chloride oxidation means loss of electrons, it's the calcium atom the oxidizes into the calcium cation +2. the chlorine is being reduced from chlorine neutral to chloride -1 anion.
No, one atom of the element Calcium (Ca) reacts with a molecule of Chlorine Gas which has two atoms of chlorine (CL2) to form on molecule of Calcium chloride (CaCl2) :-Ca + CL2 = CaCL
No. If two atoms are the same then they are of the same element. The type of atoms is determioned by the number of protons in the nucleus. A chlorine atom has 17 protons, a calcium atom has 20.
Calcium chloride.
There are many examples of atom, 106 in fact. Look at the Periodic Table of the elements.
CaCl2
Calcium ions have a charge of +2 and chlorine ions have a charge of -1. Because a compound is neutral, you need two chlorine atoms per calcium atom, thus giving us the formula of CaCl2. This tells us that there is one calcium atom in the compound.

Ca + Cl2 --> CaCl2 or Ca2+ + 2 Cl- --> CaCl2
A calcium atom will readily form Ca2+ ions while a chlorine atom will readily form Cl- atoms. Thus, ionic bonding is the only bonding that can occur between a calcium and a chlorine atom. The equation for the reaction is as follows: Ca + Cl2 --> CaCl2
calcium and chlorine combines to produce CalciumChloride (CaCl2) as chlorine needs 1 electron to complete its octate... and calcium needs to lose 2 electrons to stablized.. therefore 2 atoms of chlorine react with a single atom of calcium to stablized. Atomic numbers are as follow : Calcium 20 Chlorine 17
In Ca(ClO3)2 there are one calcium atom, two chlorine atom and six oxygen atom. So total of nine atoms
When Ca and Cl combine with each other, the electron transfer takes place from Calcium atom to Chlorine atom (i.e from Ca to Cl). In other words, the Calcium atom (Ca) loses 2 electrons and the Chlorine atoms (Cl) gains 1-1 electrons. Due to this, the Calcium becomes a positive ion (Ca 2+) and Chlorine becomes a negative ion (Cl –).
in calcium chloride each calcium atom needs to lose two electrons but each chlorine atom needs to gain only one electron. This means that two chlorine atoms react with every one calcium atom to form calcium chloride. So the formula for calcium chloride is CaCl2.ca = proton number is 20 so the structure would be 2, 8 ,8 ,2cl = proton number is 17 so the structure would be 2 , 8,7To make it stable calcium has to lose 2 electrons and chlorine has to gain an electron. However if you add 2 to 7 in the chlorine it will make 9 so it will still be unstable therefore you need two chlorine atoms to share out the 2 atoms in calcium.
