Oxygen has six (6) valence electrons. In the formation of a water molecule, two (2) of the valence electrons forms a covalent bond with two other hydrogen atoms leaving the water molecule with 2 unshared pairs of electron.

∙ 14y agoHydrogen has only one electron in it's outer shell and Iodine has seven. The bond between hydrogen and iodine uses up two electrons (one from each atom) leaving 6 unshared electrons on the iodine. So your answer would be 3 pairs of unshared electrons. If you are having difficulty with my explanation of the answer, read up on the "octet rule" on the related question below.

∙ 9y agoThere is one single shared bond between hydrogen and iodine. That means that there are three other pairs of electrons that are not bonded around the iodine atom.

Does a molecule of bromine has six unshared pairs of electrons?
Yes it does for a fact
How many extra electrons are in the Lewis structure of the phosphate ion PO 4 3?
The P04 3- ion has zero unshared pairs on the phosphorous atom and a total of 11 unshared pairs on the four oxygen atoms. The lewis structure can be represented as four different resonance structures, because an extra bonding pair is shared between the four oxygen atoms
How many lone pairs has hydrogen sulphide?
A water molecule is made up of two atoms of hydrogen and one atom of oxygen. Oxygen atom has six electrons in its outer most shell and a hydrogen atom has one electron in its outer most shell. Oxygen and hydrogen atoms are unstable because they have less than eight electrons in their outer most shells. Oxygen needs two electrons and hydrogen atom requires one electron tocomplete their valence shell. Oxygen atom combines with two hydrogen atoms by sharingelectrons. The bonds present between hydrogen atoms and oxygen atom are called single covalent bonds. In this way, oxygen and hydrogen atoms complete their outer most orbits. Oxygen shares two electrons with hydrogen atoms but its four electrons remain free in the water molecule. Therefore, there are two electron pairs or four electrons present in a water molecule.
How many lone pairs of electrons persent in a molecule of ammonia?
There is one lone pair of electrons in a molecule of ammonia: The single nitrogen atom in the molecule has five valence electrons; one of these is in a covalent bond with each of the three hydrogen atoms; and the remaining two valence electrons from the nitrogen atom constitute a lone pair.
Unlike sodium and chlorine some atoms become more stable by sharing?
they blow upinto 1 billion peices and kill everyone
How many unshardd pairs of electrons are in a molecule of hydrogen iodide?
There would be three unshared pairs of electrons in a molecule of hydrogen iodide.
Based on the Lewis structure the total number of unshared electrons pairs or nonbonding domains in the CO2 molecules is?
CO2 does not have unshared pairs of electrons.
How many unshared pairs of electrons are in CO?
2
How many unshared pairs of electrons does the nitrogen atom ammonia posses?
The nitrogen atom in ammonia has one unshared pair of electrons.
Why is the molecular geometry of water bent?
repulsive forces between unshared pairs of electrons
Does a molecule of bromine has six unshared pairs of electrons?
Yes it does for a fact
What is the electron configuration of potassium hydroxide?
K-O-H the potassium and hydrogen are in the first group of the periodic table of elements and therefor only need one set of electrons. oxygen is in the 6th, and therefor has 6 valence electrons. The oxygen also has 2 pairs of unshared electrons. K-O-H , oxygen has 2 pairs of unshared electrons.
In a tetrahedral molecule how many unshared pairs of valence electrons does the central atom have?
None
What is the name given to the pairs of valence electrons that do not participate in bonding ina diatomic oxygen molecules?
These pairs of electrons are referred to as lone pairs.
What is the molecular geometry of the molecule HI?
Hydrogen iodide Names Conjugate acid Iodonium Conjugate base Iodide Structure Molecular shape Terminus
Pairs of shared electron in methane?
None. Carbon has four electrons in it's valence shell, all of which are used in the bonds with hydrogen
What is the shape of a molecule which has three shared pairs of electrons and no unshared pairs?
Each pair of electrons will repel the others as far apart as possible. That means that the three pairs of electrons will get themselves 120 degrees apart, forming a trigonal planar shape.
