AI Generated Solution

To understand why Sn (tin), C (carbon), Si (silicon), and Ge (germanium) exhibit different electrical properties despite all being group XIV elements, we need to analyze their energy band structures and the energy gap between the valence band and the conduction band. ### Step-by-Step Solution: 1. **Identify the Elements and Their Properties**: - Sn (Tin): Conductor - C (Carbon): Insulator - Si (Silicon): Semiconductor ...

The periodicity is related to the electronic configuration. That is, all chemical and physical properties are a manifestation of the electronic configuration of the elements. The atomic and ionic radii generally decrease in a period from left to right. As a consequence, the ionization enthalpies generally increase and electron gain enthalpies become more negative across a period. In other words, the ionization enthalpy of the exterme left element in a period is the least and teh electron gain enthalpy of the element on the exterme right is the highest negative. This results into high chemical reactivity at the two extermes and the lowest in he centre. Similarly down the group, the increase in atomic and ionic radii result in gradual decrease in ionization enthalpies and a regular decrease (with exception in some third period elements) in electron gain enthalpies in the case of main group elements. The loss and gain of electrons can be co-related with the reducting and oxidising behaviour, and also with metallic and non-metallic character respectively, of the elements. Considering the elements B, C, N, F and Si , the correct order of their non-metallic character is:

The EN of the elements C, N, Si and P increases in the order of "______" .

Silicon is the second most abundant element (~27.2%) in the earth's after oxygen (45.5 %) Carbon. Silicon, germanium, tin and lead constitute the group 14 of the periodic table. Chemistry of silicon is distinctly different from that of carbon. For example, under standard conditions CO_(2) is a gas whereas SiO_(2) is a covalent solid. Group 14 elements have tendency to catenate. The first three members C, Si and Ge show significant catenation. Arrange these elements in decreasing order of their catenation tendency.

Arrange the following elements in the increasing order of non metallic character: B,C,Si,N and F.
