The elements can also be classified into the main-group elements (or representative elements) in the columns labeled 1, 2, and 13–18; the transition metals in the columns labeled 3–12; and inner transition metals in the two rows at the bottom of the table (the top-row elements are called lanthanides and the bottom-row ...
Hello,
Elements are a group of the Periodic Table that shares common valence electron structures. They are arranged in order of increasing Atomic Number.
In modern periodic table they are classified into three parts- metals, non-metals and metalloids.
In detail:-
• Metals- Metals are those elements which donate electrons. Ex- Na, K, Rb, Mg, Ca, etc.
• Non-metals- Non-metals are those elements which accept electrons. Ex- N, O, F, Cl, etc .
• Metalloids- Metalloids are those elements which show property of both metals and non-metals. Ex- B, Si, Ge, etc.
Hope it helps...
