ii. Give the names of the metalloids in the periodic table alongwith their atomic number.

iii. In which groups of the periodic table are they located?​

Answer 1

Answer:

1. Metalloids are the elements which can neither fit with metals nor with non-metals because they have properties inbetween metals and non metals.

2. The metalloids; boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po) and astatine (At) are the elements found along the step like line between metals and non-metals of the periodic table.

3. Groups 1, 2, and 13–18 are the main group elements, listed as A in older tables. Groups 3–12 are in the middle of the periodic table and are the transition elements, listed as B in older tables.
