How many electrons are shared between Cl2?
There are two electrons shared by the two Cl atoms so there is a single bond between the Cl atoms. Each chlorine has 7 valence electrons plus the one it is sharing for a total of 8 valence electrons.

How many electrons are Cl Cl sharing?
Explanation: A chlorine atom has 7 electrons in its outer shell. If it shares one of those with another chlorine atom (and the other one with the first), they can both ‘pretend’ to have 8 electrons in their outer shell, which is what they ‘want’.
Why are the shared electrons in HCl more attracted to chlorine?
There is unequal sharing of electrons. The bonded electrons are attracted more towards the chlorine as it is more electronegative than hydrogen. Therefore, the molecule develops a dipole , resulting in the dipole moment. There cannot be transfer of electrons( that is it cannot form an ionic bond ).
How many electrons does f2 have?
So the fluorine atom has eight electrons, and a filled outer shell.
Which is more stable CL or CL?
When we say “chlorine wants to gain one electron”, we speak of the radical atom. Chlorine as a free radical, Cl⋅ , is the chlorine atom that we say has 7 valence electrons and wants its 8th to form an octet. So, Cl⋅ , chlorine radical, is less stable, and Cl− , chlorine ion, is more stable.
When K+ and Cl meet they will?
K+ and Cl- form an ionic bond when potassium reacts with chlorine. Potassium transfers its outer electron to chlorine which accepts it forming KCl compound.
Is a hydrogen bond?
Hydrogen Bonding. Hydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom and another very electronegative atom.
What are the two chlorine atoms doing?
The two chlorine atoms are said to be joined by a covalent bond. The reason that the two chlorine atoms stick together is that the shared pair of electrons is attracted to the nucleus of both chlorine atoms. Hydrogen atoms only need two electrons in their outer level to reach the noble gas structure of helium.
