Homework Answers
Correct answer is a) K,Ca
The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons. ... The value of the radius may depend on the atom'sstate and context.
The unit is pm. (Picometer)
please find attached file for Atomic radius of all the given elements.
