Question

Element A belongs to Group VII in p-block and element B belongs to Group I in s-block of the periodic table. Out of the following assumptions, the correct one is : * 1 point A is a metal and B is a non-metal A and B are metals A and B are non-metals A is a non-metal and B is a metal​

Answer 1

The correct assumption is (d) A is a non-metal and B is a metal​.

• There are 4 blocks included in the periodic table which are s, p, d and f-blocks.
• The s-block consist of metals (group 1 and 2), p-block consist of non-metals, metalloids and a few metals (group 13 to 18).
• The d-block consist of transition metals (group 3 to 12) and the f-block consist of radioactive metals (group 3 only).
• Thus element A belongs to the p-block and is a non-metal and element B is metal as it belongs to the s-block.
