Question

A radioactive element P emits one α-particle and transforms to a new element Q. What will be the position of the element Q in the periodic table?

विकल्प

• One group to the left of P

• One group to the right of P

• Two groups to the right of P

• Two groups to the left of P

Answer 1

Two groups to the left of P

Explanation:

When a radioactive element emits an alpha (α) particle, its atomic number decreases by 2, resulting in Q shifting two positions to the left of its initial position P in the periodic table.
