## How many total electrons are in chlorine?

In order to write the Chlorine electron configuration we first need to know the number of electrons for the Cl atom (there are 17 electrons). When we write the configuration we’ll put all 17 electrons in orbitals around the nucleus of the Chlorine atom.

How many electrons total are in oxygen?

8 electrons
Now you can figure out how many electrons, protons and neutrons Oxygen has: Atomic number (which is always the smaller of the two numbers) is 8. Hence 8 protons. Because the atom is neutral, there are also 8 electrons.

### What is structure of ClO2?

In the Lewis structure for ClO2- we put Chlorine (Cl) at the center of the structure since it is the least electronegative. There are total of 20 valence electrons for the ClO2- Lewis structure. Remember that the negative sign counts as one valence electron.

Why oxygen has 2 lone pairs?

It contains six valence shell electrons and hence, there are three valence electron pairs in an oxygen atom. We know that oxygen forms two bonds and hence two electrons get involved in making those two bonds. So, two electron pairs are left which do not participate in bonding. Hence, oxygen has two lone pairs.

#### What is the number of valence electrons for O?

six valence electrons
Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen’s valence electrons as 2s²2p⁴.

How many electrons do carbon and oxygen share?

A carbon–oxygen bond is a polar covalent bond between carbon and oxygen. Oxygen has 6 valence electrons and prefers to either share two electrons in bonding with carbon, leaving the 4 nonbonding electrons in 2 lone pairs :O: or to share two pairs of electrons to form the carbonyl functional group.

## How many valence electrons does chlorine have?

7 electrons
The atomic number of chlorine is 17. Hence it has got 7 electrons in its outermost shell. There are 7 valence electrons in the chlorine atom.

How many neutrons does chlorine have?

18 neutrons
Not all atoms of chlorine have the same number of neutrons, however. Some atoms of chlorine have 18 neutrons in their nuclei. Other atoms of chlorine may have 20 neutrons in the nucleus. These atoms of chlorine have different atomic mass numbers.

### How many valence electrons are in the following ClO2?

Drawing the Lewis Structure for ClO. 2 The ClO2 Lewis structure has 19 valence electrons meaning that there will be an odd number of valence electrons in the structure.

How many valence electrons does cl2o?

Total valence electrons pairs For, Cl2O, Total pairs of electrons are 10 in their valence shells.

#### How many lone pairs are in chlorine?

The electron pair being shared by the atoms is called a bonding pair ; the other three pairs of electrons on each chlorine atom are called lone pairs. Lone pairs are not involved in covalent bonding.

How many bonding electrons does chlorine have?

2 bonding electrons
Cl has 7 valence electrons, 2 bonding electrons and 6 nonbonding electrons.
