Which of the following properties of Group 1 metals increases as the atomic number rises?
A. Metallic character
B. Ionic radius
C. Melting point
D. Density
E. Ionization potential
A, B & C
A and B
C, D and E
All of the above
In Group 1 alkali metals, metallic character and ionic radius increases as the atomic number rises (as we move down the group).
Density also increases down the group but there is an exception potassium.
Melting point and ionization potential decreases down the group.
