We know that it would have to be H - OH because Hydrogen can only form one BOND. Hydrogen is always on the outside of molecule. Therefore, oxygen would have to be in the middle. To draw the Lewis structure, we first put dots in for VALENCE electrons. Valence electrons are electrons available in the outer shell of an atom. Hydrogen has only 1 VALENCE electron and gets 1 dot each representing the lone electron associated with the Hydrogen proton. Oxygen has 6 VALENCE electrons. A full outer shell for oxygen would have 8 VALENCE electrons, 4 groups of 2. Therefore, we draw 2 paired electrons and 2 unpaired electrons. To form a stable compound, Hydrogen would like to have 2 more electrons in its outer shell to complete an octet of 8 electrons. Both hydrogen and oxygen will be able to have their VALENCE shell of electrons filled if they each SHARE their unpaired electrons with each other. This way, they each have a pair of electrons in COVALENT BOND between them. In the top illustration, line was drawn between unpaired electron dots. This was re - drawn for neatness sake in bottom drawing. By bonding covalently with another atom, each atom has a full VALENCE shell of electrons and remains electron neutral. The Ammonia solution used as a cleaning solution is Ammonia gas NH 3 which is dissolved in water. This can be expressed by the equation NH 3 + H 2 0 - > NH 4 + OH -. You are familiar with the pungent odor of Ammonia gas, which is also used as a respiratory stimulant. In this case, Nitrogen is the central atom. Nitrogen is in group V - of the periodic table. It has a total of 5 VALENCE electrons with 3 unpaired electrons which are available for COVALENT bonding. Hydrogen is in group IA and has one unpaired electron available for COVALENT bonding. Here line is drawn between dots representing electrons involved in each of the COVALENT bonds. When these electrons are covalently SHARE, Nitrogen has a total of 8 VALENCE electrons and each hydrogen has 2 VALENCE electrons. The Lewis dot drawing makes it clear that Nitrogen has completed its octet with 3 COVALENT bonds with Hydrogen and 1 lone pair. Nitrogen now with its full octet of VALENCE electrons is isoelectric with noble gas neon. Hydrogen with 2 electrons in its outer shell is isoelectric with noble gas helium.

Is NH3 Polar or Nonpolar?

Nh3 is a polar molecule because, in NH3 molecule, it has three dipoles of three bonds and these dipoles do not cancel out each other. They form net dipole moment. In Ammonia molecules, three atoms of hydrogen form covalent bond by sharing 3 electrons of Nitrogen and hydrogen atoms, leaving behind one lone pair of Nitrogen atom. As per VSEPR theory, lone pair on Nitrogen atom exert outward force on bond due to the shape of NH3 becomes unsymmetrical. Lone pair - bond pair repulsion drives this force on bonds. And the calculated electronegativity of Nitrogen is 3. 04 and of hydrogen is 2. 2 Therefore, differences in their electricity cause three dipole moments from three N - H bonds in one direction. Three dipoles in one direction form net dipole moment that determine NH3 polar molecule. In N - H bond, Nitrogen being more electronegative pulls electron pair slightly towards itself and becomes partially negatively charge. Ammonia gas is highly soluble in water, forming ammonium ions and it should be noted that polar molecules get more easily mixed with another polar molecule. And as we know, water is also a polar molecule. Therefore, Ammonia and water attract each other and get easily mixed. It is important to know fact that apart from this polarity factor, they have an extra booster of attraction that is known as hydrogen bonding.
