Lets see some of the similarities between ionic and covalent bonding and compounds here on this page:
Similarities between Ionic and Covalent Bonding and Compounds
1. Both types involve multiple atoms coming together to form a more complex structure.
2. In both types, bonding yields a compound that has different properties than the original elements.
3. Both types of bonding result in atoms becoming more stable in the group than they were individually.
4. Both types of bonding are exothermic as the potential energy of the participants is lowered as they form the bond.
5. Both types of compounds involve the interaction between valence electrons.
6. In both types of bonding the attractive force is an electrostatic one whereby opposite charges attract – there is no physical matter holding the atoms together.
7. In the solid, crystalline state, both types lead to regular, ordered patterns and structures.
8. Both types of compounds can undergo changes in physical state under the right conditions of temperature and pressure.
9. Both types of compounds have a net neutral charge.
10. Both types of compounds contain a fixed ratio of participants that is represented by the subscripts in their chemical formulas (they do not require a 1:1 ratio).
