Cl has 7 valence electrons. 4 of these are used in the single bonds to the hydrogen atoms, leaving 3 for the lone pairs.
Cl has 7 valence electrons. There are 4 lone pairs and 3 bonding pairs.
How Many Lone Pairs Does O Have
Oxygen is a highly electronegative element, meaning that it strongly attracts electrons to itself. This results in oxygen atoms having a full outer shell of eight electrons – two more than the six electrons found in most other atoms.
The presence of these extra electrons gives oxygen a negative charge, and this charge is evenly distributed across the atom’s surface.
As a result, each oxygen atom has four pairs of electrons around it – known as lone pairs – which are not involved in bonding with other atoms.

How Many Bonds And Lone Pairs Does Cl Have?
chlorine has 7 valence electrons. It can form 1 covalent bond and have 3 lone pairs.
How Many Bonds And Lone Pairs are in C?
In chemistry, a bond is a lasting attraction between atoms, and typically refers to the sharing of electrons between them. The number of bonds that an atom can form is determined by its valence electrons – those in the outermost orbital. Carbon has four valence electrons, so it can make four bonds.
In addition, carbon can form double or triple bonds with other atoms. Lone pairs are pairs of electrons that are not shared with another atom – they’re “lone.” So, in answer to the question, carbon can make four bonds and has two lone pairs.
Does Chloride Ion Have Lone Pair?
Chloride ion, #”Cl”^(-)#, is a monovalent anion with 18 electrons around the central chlorine atom. Of these, 7 are valence electrons in the 3s and 3p orbitals.
The remaining 11 electrons fill the inner shells of the atom.
The chloride ion has no lone pairs because all of its valence orbitals are filled.
How Do You Calculate Lone Pairs?
In order to calculate lone pairs, you’ll need to first identify the number of valence electrons on the atom in question. This can typically be done by looking at the periodic table, as the columns represent elements with similar valence electron counts. Once you know how many valence electrons there are, you can subtract that number from eight (8).
This will give you the total number of lone pairs present on the atom.
The total number of lone pairs in a chlorine molecule is
Conclusion
Chlorine has 3 lone pairs and 1 bonding pair. This gives it a total of 4 pairs of electrons around the central atom.
