Question

Element X belongs to 4th period it contains 18 and 1 electron in in the penultimate and ultimate Orbit the x should be

Answer 1

The complete question is:-

Element X belongs to the 4th period it contains 18 and 1 electron in the penultimate and ultimate Orbit, the x should be:

(a) Normal element

(b) Inert gas

(c) Transition element

(d) Inner transition element

Answer:-

X should be a transition element.

• Since it is given that the element has 18 and 1 electron in the penultimate and ultimate orbits respectively, we can deduce the electronic configuration of the element.
• The number of electrons in different shells will be as follows:- 1s², 2s², 2p⁶, 3s², 3p⁶, 3d¹⁰, 4s¹
• This suggests that the given element belongs to the transition series of the periodic table.

Answer 2

X is a Transition Element
