Group IV-A Elements This group of elements is placed in middle of periodic table. Group 4A (or IVA or group 14) elements of the modern periodic table includes the nonmetal carbon (C), the metalloids silicon (Si) and germanium (Ge), the metals tin (Sn) and lead (Pb), and ununquadium (Uuq). Melting and Boiling Point of group 4 A …
Peculiar Behaviour of Beryllium: Beryllium is the s-block element of the modern periodic shows some differences from the rest of the members of its family. The electronic configuration of Beryllium is 1s2 2s2 The anomalous properties of beryllium is especially due the following reasons: small size high electronegativity high ionization energy high polarizing power (i) Beryllium atom …

Group II-A Elements of periodic table Be (Beryllium) Mg (Magnesium) Ca (Calcium) Sr (Strontium) Ba (Barium) Ra (Radium) Alkaline earth metals are the most reactive metals in the periodic table after alkali metals (Group IA). Group II A elements having a valence shell configuration of ns2 (full filled orbitals). Alkaline earth metals (Group II A …
Group 1 Elements alkali Metals Occurrence, Physical and Chemical Properties, Reactivity and Compounds Group I-A Elements Elements of Group I-A are called alkali metals due to the alkaline nature of their oxides and hydroxides. Namely, Lithium (Li) , Sodium (Na) , Potassium (K), Rubidium (Rb) , Cesium (Cs) and Francium (Fr) are group 1A elements …
Anomalous Behavior of Lithium in its group: Lithium being 1st member of the group 1 with the symbol Li and atomic number 3 and electronic configuration of 1s2 2s1 shows some differences from the rest of the members of its group. (i) Melting and boiling point of Lithium are much higher than other members of its …

Trends in Chemical properties of elements in period 3 : Period 3 of the table consists of Sodium, Magnesium, Aluminum, Silicon, Phosphorus, Sulphur, Chlorine and Argon. They can be roughly divided into metals (Na, Mg and Al), metalloids (Si) and non-metals (P, S, Cl, and Ar), and therefore the elements within these groups tend to …
