Na+ and Cl- ions are formed, which then results in the formation of the ionic compound NaCl.

What does chlorine become when it gains one valence electron?
A negatively charged "ion".
How many valence electrons does a chlorine atom have if its electron configuration is Ne 3s2 3p5?
Seven.
How many electrons will chlorine gain from forming an ion?
Chlorine will gain one electron when forming an ion. Chlorine therefore fills its valence electron shell with 8 e-. Chlorine usually bonds with group 1 metals, like Na (Sodium).
When a chlorine atom gains an electron it fills its valence shell forming a negative chloride what?
The chloride ion is an anion (Cl-).
What role do valence electrons play in whether an atoms bond to another atom or not?
They play a HUGE role. This is because this is the most fundamental principle that governs chemical reactions. For example, the classic tablesalt compound. Sodium (Na) has a single valence electron, while Chlorine (Cl) has seven valence electrons. Elements of this size (atomic mass) usually want to have a total of 8 valence electrons. Well guess what? Sodium wants to get rid of that bothersome electron to have a complete shell rather than another incomplete shell. Chlorine wants to fill its shell so it happily takes it. Now Sodium has a filled shell and so does Chlorine. This means that sodium is positive and the chlorine is negative and so they bond from the difference in charge. Voila we have tablesalt. This is just one of many examples showing the importance of valence electrons in chemistry. This was an example of an ionic bond because an electron was completely given and not shared like in a covalence electron. The term "covalence" implies that the valence electrons will co-exist between the atoms, like in water (H20).
Number of valence electron of chlorine?
There are 7 valence electrons in chlorine.
How many valence electron does chlorine?
The element chlorine has seven electrons in its valence shell.
Is the correct valence electron for chlorine 7?
yes, chlorine has 7 valence electrons
What is the valence number of electron in chlorine?
7
Why does the transfer of an electron occur between a sodium atom and a chlorine atom?
Chlorine is extremely electronegative and will steal electrons from the valence shell of sodium. When chlorine steals the electron, both sodium and chlorine have full valence shells.
What happens to sodiums valence electron when sodium bonds with chlorine to form table salt?
The electron is transferred to chlorine.
When sodium and chlorine react the outermost electron of the sodium atom is?
Valence electron - Sodium loses one electron to form a sodium ion (valence of 1).
What is the most common oxidation number of the element chlorine?
Chlorine is in group 17. It easily accepts an electron from another element to fill its valence shell. As it takes one electron, its oxidation number changes to -1.
Will chlorine gain an electron?
Chlorine atoms have 7 outermost electrons and need to gain an electron to achieve the stability of a full valence shell.
What is the valence shell for chlorine?
There are 7 electrons on the valence shell. Chlorine requires one electron to make it complete and the ion would therefore be Cl- (one minus charge)
How many electrons does chlorine need to have a full outer shell?
1 additional electron will give chlorine 8 in the valence. You can see in the Periodic table, that Chlorine is next to Argon ( 1 to the left of it) so it needs 1 more electron to have the same configuration as Argon.
What does chlorine become when it gains one valence electron?
A negatively charged "ion".
