Different elements have different electro-negativities. Electro-negativity is the ability of an atom to withdraw 'electron density' towards itself, i.e. it makes electrons com…e closer to it. Fluorine is the most electronegative of the elements. Oxygen is more electronegative than hydrogen and so in water (H2O) the oxygen 'pulls' the electrons closer to itself and become slightly negative, and the hydrogen's slightly positive, this is called a permanent dipole. Due to this effect water has many properties that make it unusual and important to living things.
A polar molecule has two poles, a negative pole and a positive pole (which is the result of an asymmetrical distribution of electrons). And in accordance with Coulomb's Law, o…pposite charges will attract, and same charges will repel. So polar molecules will arrange themselves so that the oppositely charged poles face each other, and thus are attracted.
yes. the positive end of the molecule attracts the negative end of the adjacent molecule
Water is a polar molecule! Because of this uneven distribution of charge, water is also called a polar compound.
Nope, its FALSE :)
Water molecules have a polarity which allows them to be electrically attracted to other water molecules and other polar molecules by weak chemical bonds known as?
Hydrogen bonding. Water molecules electrons are not sharred evenly between the hydrogen and oxygen atoms. The easiest way to explain it is that the oxygen atom "hogs" the elec…trons. Since it has 8 protons in it's nucleus the oxygen has a greater pull. Hence the oxygen is slightly negative (negative charge of electrons) and ther hydrogen side has a slightly positive charge. Hydrogen bonding is part of the category known as Van Der Wall forces. Basically, the hydrogen part of the water molecule bonds with a slightly negative part of another molecule. This allows for adhesive and cohesive bonding cababilities of water.
Water molecules attract the opposite poles of other polar molecules through poles present in water itself.
A water molecule is polar, which is why it attracts other polar molecules.
yes it does because the more the cohesion energy density of both molecules is close the more ability they have to fuse together
