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

∙ 14y agothey just do and form sodium chloride aka table salt.
...wow, what a GREAT answer

∙ 13y agoYes, The chemical formula of calcium chloride is CaCl2.

Ca(2+)
Cl(-)
so, you need two chlorine's to go with one calcium, each chlorine atom accepts one of the calcium electrons.

How many atoms of sodium will combine with one atom of chlorine?
1
How many chlorine atoms are needed to link up with one calcium atom?
two
How many atoms are present in CaCl2?
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.
Ca2 plus CL equals CaCL2?
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
How many atoms are in hydrogen and chlorine?
There is one atom in Hydrogen and one atom in Chlorine. All elements are composed of only one atom.
How many potassuim atoms combine with a chlorine atom?
one
The formula contains one calcium atom and two chlorine atoms?
Calcium chloride.
Why is Calcium Chloride covalent?
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 –).
How many atoms of sodium will combine with one atom of chlorine?
1
How can magnesium give away 2 electrons to chlorine?
One, but there is a catch. One magnesium atom will combine with two chlorine atoms to make magnesium chloride (MgCl2). The magnesium will give one electron to eachof two chlorine atoms to create this metal salt.
What is the formula One calcium atom for every two chlorine atoms?
CaCl2
What happens if a calcium atom loses an electron to a chlorine atom?
Because calcium has 2 valence electrons, it needs to get rid of them to have a stable noble gas conformation. Chlorine atom has 7 VE and only needs to gain one electron to have the noble gas conformation. Therefore one calcium will give one electron to two chlorine atoms, therefore resulting in an ionic bond.
How many chlorine atoms are needed to link up with one calcium atom?
two
What is the number of calcium atoms in calcium chloride?
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.
Do molecules combine to form atoms?
Yes. For example, one sodium atom and one chlorine atom combine to make sodium chloride, commonly known as table salt. Two hydrogen atoms and one oxygen atom make water.
How many atoms of chlorine combine with one atom of zinc to form a molecule of zinc chloride?
The formula for Zinc Chloride is ZnCl2. That means that for every 1 atom of Zinc there are 2 atoms of chlorine.
Why is calcium oxide CaO but calcium chloride is CaCl2?
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.
