What are the three types of chemical bonds Define and give an example of each?

Answer 1

Covalent= Atoms 'share' electrons to gain full outer shell/noble gas electron shell configuration. Between non-metals, e.g CO2- Carbon Dioxide, O2- Oxygen gas

Ionic= Electrons are donated from the outer shell of one atom (to become an ion) to another atom (which also becomes an ion) so both gain full outer shells. It is defined as the electrostatic attraction between oppositely charged ions. Between non metals and metals, e.g NaCl- Sodium Chloride

Metallic= The attraction between postive metal ions and negative delocalised electrons. e.g any metal, or alloy- Mg, Na, Fe etc

Answer 2

Ionic bond is that type of bond which is formed by tranferance of single electron from one atom to other.Covalent bond is that type of bond which is formed by equal or matual sharing of electrons between one atom to another is called covalent bond.eg of ionic bond isNacl the atomic of Na (sodium) is 11 and atomic no. Clorine is17 the electronic confrigation of Na is 2,8,1 and of Cl is 2,8,7 the Na lose 1 electron for stableness and give it to Cl so charge on a Na is ve then eletronic confrigation of Na is 2,8 and Cl gains 1 electron from Na and its electronic confrigation will be 2,8,8 and charge it will be -ve, both of them are stable and have a opposite charge and make compound known as Nacl.
