2. What is a Chemical bonding- Is when Ionic bonds, Covalent bonds, and metallic bonds by the Atom or Ion Bonded in a molecule or crystal.

3. What is a covalent Bond-Boned formed by sharing of electrons between atoms. Atoms that are held together by sharing electrons are usually going to be joined by covalent Bond. Electrons take place between the atoms bonding them together.

4. What is Single covalent bond- It is Bond formed when two atoms share a pair electrons. In this Bond the Hydrogen molecules are held together by the attraction of the shared electrons. The pair of sharing electrons are mainly joined by the Single covalent Bond.

5. What is Double and Triple Covalent Bond- Triple Bond-It is a bond formed by sharing three pairs of electrons. Double Bond- bond involves two shared pairs of electrons. Atoms form Double and Triple Bond by them attaining a noble gas structure by sharing two or three pairs of electrons.

6. What is Coordinate covalent Bonds- It is a Covalent bond in which one atom contributes both bonding electrons. In this bond the shared electron pair comes from the bonding atom. In this bond the atom donates the electrons to the receiving atom. Formulae carbon monoxide with two covalent bonds is-C  0

7. What is a Polar Covalent Bond- It is a Covalent bond between atoms in which the electrons are shared unequally. In this bond the more electronegative atom attracts electrons the more strongly plus it gains a slightly negative charge. The higher the electro negativity value the greater the ability of the atom.
