What are the three sub atomic particles

Protons


Electrons


Neutrons

Ionic bond

Chemical bond in which a strong mutual attraction links ions of opposite charge.

Covalent bond

Chemical bond in which two atoms share a pair of electrons

Covalent bond

Chemical bond in which two atoms share a pair of electrons

Hydrogen bond

Attractions between a Covalently bonded hydrogen atom and another taking part in a separate covalent bond

Cohesion

Property of substance that arises from the tendency of it molecules to resist a separation from one another

Why is water considered a polar molecule ?

Overall the molecule has no charge but the oxygen atoms carries a slight negative charge; the hydrogen atom a slight positive charge

Considering water,Which state of matter (liquid or solid) exhibits greater density

Water holds a higher density because Ice is less densely packed.

The PH scale

7 is a neutral.


The amount of hydrogen ions in a solution.


-hydrogen ions abundant in acid

BUFFER

A Buffer is a set of chemicals that can keep the Ph stable by alternately donating and accepting ions that contribute to a PH

Carbon

The most versatile because it has 4 vacancies. Can form 4 covalent bonds with other atoms.
