Answer to Question #153337 in Inorganic Chemistry for Wilder

Question

List all the metals of the first series of transition metals in order of increasing atomic number

How does the atomic radius of the elements vary across the series ? Explain

Answer 1

(a) List of the first series of transition metals in increasing atomic number;

Sc - 21

Ti-22

V-23

Cr-24

Mn-25

Fe-26

Co -27

Ni-28

Cu-29

Zn -30

(b) How atomic radius varies across the series.

• Atomic radius decreases from Sc to Zn
• This is because of an increase in atomic number (number of protons ) in the nucleus/nuclear charge. Increased nuclear charge pulls the electron cloud more strongly towards the nucleus making the atoms with the same number of shells shrink across the series.
