d. F, Cl, S

e. F, S, Cl

2)Which of the following lists of atoms are arranged in order of DECREASING atomic radius? The largest diameter atom is on the left and the smallest diameter atom is on the right

a. Na > Sr > O > F

b. Li > N > O > F

c. F > O > N > Li d. Li > O > N > F

e. Ca < Cs < S < Se

Expert Solution

The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the nucleus to the boundary of the surrounding cloud of electrons.

Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. Three widely used definitions of atomic radius are: Van der Waals radius, ionic radius, and covalent radius.

I am attaching a peridic table of the atomic radii will help.

As per this table the correct answer for question 1) is d. F, Cl, S

2) DECREASING atomic radius

correct answer is b. Li > N > O > F
