The structure of water molecules and how they can interact to form hydrogen bonds.

I'm not great at science in general, so I don't understand what a polar molecule is and why water is a polar covalent bond is. • (14 votes) Jamie 9 months agoPosted 9 months ago. Direct link to Jamie's post “a bond is when 2 or more ...” a bond is when 2 or more elements combine chemically and create a molecule. Elements bond either by sharing or transferring electrons. When a bond is formed by sharing electrons, it's called a covalent bond. sometimes the electrons in a covalent bond are shared unequally which causes some parts of the molecule to be partially positive and other parts to be partially negative. When this happens, its called a polar molecule. In water, the oxygen atom gets the electrons more frequently than the two hydrogens because of unequal sharing. This causes the side of the molecule with the oxygen to be partially negative and the side with the hydrogens to be partially positive, making water a polar covalent molecule. hopefully that helps :) (117 votes) Hi Nice to meet you 7 years agoPosted 7 years ago.

Direct link to Dovid Shaw's post “When one atom "shares" an...” When one atom "shares" an electron with another atom to form a molecule, the atom with higher electronegativety (electron-greedy) will keep the shared electrons closer to itself than to the partner-atom. Since one atom gained an electron and keeps it near itself, the atom receives a "partial negative charge." It isn't fully charged because the molecule is neutral due to its balance of negative and positive regions. (45 votes) yuvalboek1971 6 years agoPosted 6 years ago.

Direct link to tyersome's post “That is generally a safe ...” That is generally a safe assumption, but should not be regarded as a "law". An example that doesn't fit this rule perfectly is Also, note that hydrophilicity and polarity are both continua, so there are many molecules that are in the middle of both of these scales. There are also many polyatomic ions (not formally molecules since they have charges) that are very hydrophilic, but also completely non-polar because they are symmetrical. Examples include: ammonium (NH₄⁺), sulfate (SO₄²¯), carbonate (CO₃²¯), and oxalate (C₂O₄²¯). It is also worth remembering that single atom ions (e.g.s (13 votes) Chadislav 8 years agoPosted 8 years ago.

Your bones are made from cells called osteoblast, they arent cells, but a type of cement made by these cells. Your epidermis (skin) holds all the water in you together. Your blood cells have water, your muscles have water, your neurons have, water. Most of you is water. I hope that makes sense and helps :) (7 votes) Pardhu Kaknuri 8 years agoPosted 8 years ago.

Direct link to Farhath's post “Polar molecules, such as ...” Polar molecules, such as water molecules, have a weak, partial negative charge at one region of the molecule (the oxygen atom in water) and a partial positive charge elsewhere -(the hydrogen atoms in water). Thus, when water molecules are close together, their positive and negative regions are attracted to the oppositely-charged regions of nearby molecules which makes it bond! and even the answer- to become neutral is also correct! for more information visit-http://www.biology-pages.info/H/HydrogenBonds.html (5 votes) Voldigoat27 6 months agoPosted 6 months ago.

p.s. More electrons = negative charge, fewer electrons = positive charge.CO₂, which is non-polar, but still somewhat soluble in water — this is in part because it reacts with water, but also because of weak effects due to the presence of polar bonds within this non-polar molecule.Na⁺, Cl¯, Mg²⁺) are hydrophilic but not polar.
Evaporation: When the temperature raises high enough, the water particles begin to move faster and gain more kinetic energy. As they move faster, the particles spread out in all directions. This spreading converts the water into a gas, or water vapor.
Condensation: The temperature slowly or slightly drops to where the water vapor's particles begin to slow. The decrease in speed makes the particles come closer together, making small droplets.
Precipitation: When the droplet or cloud gets full with water, the density makes the water fall, making it rain. If the temperature is cold enough, the rain droplets will freeze as the particles slow, making snow.
