Question

Considering periodic trends, valence electrons in which of the following atoms experience the greatest effective nuclear charge (Zeff)? A) CI. B) С. C) F. D) Ne. E) В +.

Answer 1

Step-by-step explanation:

Solution :

Effective nuclear charge trends ;

Effective nuclear charge increase from left to right across a period .

Effective nuclear charge decrease from up to down in a group .

B , C , F and Ne belongs to period number 2 and Cl belongs to period number 3 .

Ne comes in the last position of period 2 . So , Ne have greatest effective nuclear charge in period 2.

F and Cl belong to same group number 17 . So , F and more effective nuclear charge than Cl .

So , noble gas Ne have greatest effective nuclear charge in given elements .

Correct option : ( D ) Ne
