Does calcium and chlorine have the same atoms?

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.


The formula contains one calcium atom and two chlorine atoms?

Calcium chloride.


What examples of an atom?

There are many examples of atom, 106 in fact. Look at the Periodic Table of the elements.


What is the formula One calcium atom for every two chlorine atoms?

CaCl2


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.


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.


If chlorine can accept 1 Calcium and chlorine atoms combine in the ratio of what atoms to 1 what atom?

Ca + Cl2 --> CaCl2 or Ca2+ + 2 Cl- --> CaCl2


What type of a chemical bond would expect between a calcium atom and a chlorine atom?

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


Why does one calcium atom combine with two chlorine atom?

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


What is the total number of atoms in the compound Ca (ClO3)2?

In Ca(ClO3)2 there are one calcium atom, two chlorine atom and six oxygen atom. So total of nine atoms


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 –).


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.
