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.
Why does Na bond to Cl?
Sodium can lose its one valence electron to form noble gas configuration. Chlorine will accept one electron to form noble gas configuration. Hence a ionic bond will e formed between sodium and chlorine.
What happens when a chlorine atom gains electron in its outer energy shell?
When a chlorine atom, which normally has 7 electrons in the valence shell, gains an electron, it achieves a stable state similar to the noble gas, having 8 electrons in the outer shell. This results in the formation of the chloride ion, Cl-.
What is the formula to make chlorine dioxide?
Simply add o2 (oxygen) and cl2 (chlorine gas by burning salt)
Why does chlorine like to form the ion chlorine Cl-?
It does so because it gains an extra electron in order to attain a noble gas state, i.e. in order to contain the same # of electrons as a noble gas. in the case of Chlorine, that gas is Argon which has an atomic # of 18, therefor having 18 electrons. Chlorine has an atomic # of 17. In order to be monoatomic with Argon, it gains an extra electron to have a total of 18 electrons. Since it now has 1 more electron than protons, it's charge is -1. Therefore, it is written as Cl-.
How many electrons does chlorine gain to make a noble gas?
Chlorine gains 1 electron to achieve the noble gas electron configuration of argon.
What does chlorine do to get noble gas configuration?
Gain an electron.
What happens if a calcium atom loses an electron to a chlorine atom?

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.
What happens when poisonous chlorine gas gains an electron?
It turns into a nice, safe chloride ion, which is the most common negative ion in your body.
How many electrons does chlorine need to be a noble gas?
Chlorine need one extra negatively charged electron to be a noble gas.
Why a pale green gas is used in swimming pools?
Chlorine gas dissolves in water and breaks the cell walls of bacteria thus killing them. Most pools do not actually add chlorine gas; they add chlorine compounds which slowly break down in water and release chlorine. They're much safer and easier to store and work with than the gas itself.
What is the noble gas electron configuration of choline?
Chlorine Electron configuration - [Ne] 3s 2 3p 5
What happens when chlorine atom gains an electron in its outer energy?
No! Electrons are negatively charged. A neutral atom gaining a electron will, by necessity, become negatively charged. Cl(-)
Does element cl have a noble gas electronic configuration?
The element chlorine does not have noble gas configuration. But chloride ion formed (when chlorine accepts an electron) has noble gas configuration of argon.
What happens to chlorine at 100 c?
remains a gas
Why does Na bond to Cl?
Sodium can lose its one valence electron to form noble gas configuration. Chlorine will accept one electron to form noble gas configuration. Hence a ionic bond will e formed between sodium and chlorine.
Why is chlorine a reactive non metal?
Because a chlorine atom only needs one more electron to achieve a noble gas configuration.
