Which element forms ion with charge +3:
Correct answer: B. Aluminium
- A. Beryllium
- B. Aluminium
- C. Carbon
- D. Silicon
Explanation
The Group IIIA of the Periodic Table comprises the elements boron, aluminium, gallium, indium and thallium So as Al belongs to 3A group so it has 3 electron in valence shell so its ion has +3 charge

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
