Is water a polar molecule True or false?

Water molecules have an attraction for each other because they are polar molecules. They have a slight negative charge near the oxygen atom and a slight positive charge near the hydrogen atoms. The positive part of one molecule attracts the negative part of another.

Do water molecules have positive and negative parts?

There is no overall charge to a water molecule, but there is a slight positive charge on each hydrogen atom and a slight negative charge on the oxygen atom. Because of these charges, the slightly positive hydrogen atoms repel each other and form the unique shape seen in [link].

Is polar molecule negative or positive?

A polar molecule is a molecule in which one end of the molecule is slightly positive, while the other end is slightly negative. A diatomic molecule that consists of a polar covalent bond, such as HF, is a polar molecule.

What is water called a polar molecule?

Water is a “polar” molecule, meaning that there is an uneven distribution of electron density. Water has a partial negative charge ( ) near the oxygen atom due the unshared pairs of electrons, and partial positive charges ( ) near the hydrogen atoms.

Why is chlorine always Cl2?

Chlorine is called Cl2 because it is a diatomic molecule. Diatomic means there are two atoms of the same elements in the molecule. There are other diatomic molecule, such as hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (Br2), iodine (I2).

Is chlorine a liquid or gas?

Chlorine is a greenish yellow gas at room temperature and atmospheric pressure. It is two and a half times heavier than air. It becomes a liquid at −34 °C (−29 °F).

Why chlorine is a non metal?

Chlorine is a nonmetal because it does not have the characteristics of a metal. It cannot conduct electricity, it is not flexible, and it is not hard….১৪ জানু, ২০১৯

Is chlorine a non-metal element?

Oxygen, carbon, sulfur and chlorine are examples of non-metal elements. Non-metals have properties in common.

Is chlorine a non?

Chlorine is the second halogen, being a nonmetal in group 17 of the periodic table. Its properties are thus similar to fluorine, bromine, and iodine, and are largely intermediate between those of the first two.
