(a) Interpretation: In the given set of elements, the element that has the smallest atomic size is to be stated. Concept Introduction: The distance between the nucleus and the valence shell electrons of an atom is known to be the atomic size of that atom. According to the periodic table, the atomic size increases while going down the group and decreases while moving from left to right in the period.

Please correct answer and don't used hand raiting
Consider the following Figure 2 and two atoms that are initially an infinite distance apart, x =00, at which point
the potential energy of the system is U = 0. If they are brought together to x = x, the potential energy is related
to the total force P by
dU
dx
= P
Given this, qualitatively sketch the variation of U with x. What happens at x=x? What is the significance of
x = x, in terms of the potential energy?

Figure 2. Variation with distance of the attractive, repulsive, and total forces between atoms. The
slope dP/dx at the equilibrium spacing xe is proportional to the elastic modulus E; the stress σb,
corresponding to the peak in total force, is the theoretical cohesive strength.
