Question

The element with atomic number (Z = 74) belongs to 1) Group 17, period 6, p-block 2) Group 3, period 6, f-block 3) Group 6, period 6, d-block 4) Group 14, period 6, p-block ​

Answer 1

• Atomic number 74 corresponds to Tungsten.

       The electronic configuration of tungsten is [Xe] 4f¹⁴5d⁴6s²

       So, it belongs to group 6, period 6, d-block

• The symbol of tungsten is W.

          It is called Wolfram, and therefore the symbol is W.

• It is a member of d-block elements and belongs to VI (b) group.

The melting point of tungsten is very high and it is because of this reason that tungsten is widely used as filament in light bulbs.

It can tolerate very high heat and therefore will not meltdown

Answer 2

• From the question, the correct option is 3.

• As we know that tungsten element has 74 atomic numbers.

• The element belongs to group 6, it belongs to period 6 and it is a d-block element.

• It is represented by the W chemical symbol. it has a high density and high melting point.    

• It is a metal, lustrous and grayish-white color element.

• So it belongs to; Group 6, period 6, d-block.
