Fluorine (F) and chlorine (Cl), as group 17 elements, have seven electrons in their outermost shells. They tend to achieve a stable octet by taking an electron from other atoms, becoming negatively charged ions: F− and Cl−. Carbon (C), as a group 14 element, has four electrons in its outer shell.

For ICl3, we have 7 valence electrons for Iodine; 7 for Chlorine, but we have three Chlorines; a total of 28 valence electrons. I is the least electronegative, put that in the center, and then Chlorines will go around it. Put two electrons between the atoms to form chemical bonds.

XeF4 is non polar. It has 4 bond pairs and 2 lone pairs, hence it has a square planar shape.

The complete Lewis structure is: Thus, we can see that SF5- have 1 pair of nonbonding electrons in the central atom. The answer is 4.

Christopher P. A neutral chlorine atom has 17 protons (atomic number 17) and 17 electrons. The first two electrons are located in the 1s orbital. In the second energy level, two electrons are located in the 2s orbital, and six electrons in the three 2 p orbitals.

The ClF bond is a polar covalent bond and the molecule has a net dipole moment (unlike CCl4 for instance where the bond dipoles cancel giving the molecule no net dipole moment).

There are seven electrons in the highest occupied energy level of a chlorine atom. These electrons occupy the s and p sublevels, and make up the valence shell.

When one electron is added to outer shell orbital then Chlorine forms Cl-. Hence the electron configuration of the Chloride ion is . All the electrons in the orbitals are paired up hence there is no electrons are free in the orbital. Hence the unpaired electrons present in the Cl- are zero.

CCl2F2 consists of 2 chlorine and 2 fluorine atoms bound to the carbon, the difference in electronegativity is different in the C-F bond and the C-Cl bond, and cannot “cancel out” despite the tetrahedral shape. Therefore, CCl2F2 is polar.

Lone pairs of electrons are found in nonbonding orbitals, i.e. they are not being used to bond. Therefore, they do not count as σ -bonding pairs.

Neutral chlorine has 17 electrons. To achieve a single negative charge, the neutral atom must gain one electron. The net result is that the chloride ion Cl- has 18 electrons.

Despite its electronegativity, size of a chlorine atom is larger and hence, the electron density is low. So, HCl does not have hydrogen bonding but, HF,NH3,H2O shows hydrogen bonding.

1 Answer. A fluorine atom has 4 pairs of electrons + 1 unpaired electron. Fluorine is located in period 2, group 17 of the periodic table, and has an atomic number equal to 9.

In the diagram, you can see there are ten electrons, six in the triple bond between the carbon and nitrogen atoms and an unshared pair of electrons on both the nitrogen and the carbon atom. The ten electrons represent the sum of all the valence electrons in the molecule plus or minus any charge if it's an ion.

Explanation: In the O2 molecule, there is a double covalent bond formed due to the sharing of electrons. Since two electrons form each bond, there are a total of two pairs, or four electrons, in the bond.
