Question

Give an example of ionic and covalent bond, and explain and make an example for each.

Answer 1

Well, ionic bonding is the type of  bonding in which electrons are transferred from one atom to another. While covalent bonding is the type of bonding in which the electrons are shared between the two atoms of the elements. An example of ionic bonding is sodium and fluorine. Sodium transfers one electron to flourine which has 7 outer shell electrons.  The electrons are then made 8, which is complete. Sodium has one outer shell electron which cannot stay alone, so is transferred.
  An example of covalent bonding is between two hydrogen atoms to form H₂
 The two atoms come together and combine, they are attached to each other. 

Answer 2

An ionic bond is formed by the transfer of electrons from electronegative elements to electropositive elements.

Some examples of compounds where ionic bonds are formed

1. Sodium Chloride (NaCl)
2. Magnesium Chloride (MgCl₂)
3. Potassium Iodide (KI)

A covalent bond is formed by the sharing of electrons between 2 atoms.

Some examples include :

1. Methane (CH₄)
2. Ammonia (NH₃)
3. Water (H₂O)
