(b)
Interpretation:
Whether the elements rhodium, cadmium and tin are present in same group or period in the periodic table should be determined.
Concept Introduction:
An atom is composed of three main sub-atomic particles; electrons, neutrons and protons. The atomic number of the elements represents the number of protons or electrons in a neutral atom. All known elements are arranged in a tabular form in increasing order of their atomic number that is called as the periodic table. The distribution of electrons in an atom can be shown with the help of electronic configuration. The electronic configuration of an element represents the number of electrons in different energy levels of an element.

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? 0 P, Force 19 Attraction Total Repulsion x, Distance 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.arrow_forward
