Question

Consider the elemts Ca,Ba,As, and Bi. Which has the...

largest radius?
highest electronegativtity?
Highest Ionization Energy?

Answer 1

Symbol Element Atomic Radius Electronegativity Ionization Energy
Ca Calcium 194 pm 1 57110 kJ/mol
Ba Barium 253 pm 0.89 3.6 x 10³ kJ/mol
As Arsenic 114 pm 2.18 12310 kJ/mol
Bi Bismuth 143 pm 2.02 8520 kJ/mol

Based on the above information.
The element with the largest radius is Ba.
The element with the highest electronegativity is As
The element with the hightest Ionization energy is Ca.
