WebThe periodicity of properties of the elements is caused by the periodicity in electronic structure. The noble gases are chemically unreactive, or nearly so, because their electronic structures are stable—their atoms hold their quota of electrons strongly, have no affinity for more electrons, and have little tendency to share electrons with other atoms. An element … WebJun 26, 2024 · 7. 2.Some families in periodic table Group 1A Alkali metals because they form alkalis with water. Group 2A Alkaline earth metals due to their alkali nature and abundance in earth crust. Group 7A halogens due to their salt forming properties.
