Chapter – 4 Carbon and its compounds

  1. Read the following carefully.

In covalent compounds atoms share valence electrons to satisfy the octet. Each atom shares one pair or two pairs or three pairs of electrons depending on their combining capacity. In electron dot structures only number of valence electrons are shown around the symbols of constituent atoms. Carbon using its valency of four can make either single, double or triple bonds with other carbon atoms or any other atoms. Carbons self-linking property is called catenation. In hydrocarbons carbon makes aliphatic or cyclic molecules they are either saturated or unsaturated. Based on these facts Read the following paragraph and answer the questions given below. An element X combines with Y to form a colourless odourless gas, Z which turns lime water milky is the major constituent of all organic molecules.

Q. Read the following and answer the questions.

Today, 118 elements are known, the first 94 of which occur in nature. Of the 94 natural elements, eighty are stable.The periodic table is a graphic description of the periodic law, which states that the properties and atomic structures of the chemical elements are a periodic function of their atomic number. Elements are placed in the periodic table by their electron configurations, which exhibit periodic recurrences that explain the trends of properties across the periodic table. As we go across a period from left to right, we add a proton to the nucleus and an electron to the valence shell with each successive element. As we go down the elements in a group, the number of electrons in the valence shell remains constant, but the principal quantum number increases by one each time. An understanding of the electronic structure of the elements allows us to examine some of the properties that govern their chemical behavior. These properties vary periodically as the electronic structure of the elements changes.They are

(1)  size (radius) of atoms and ions,

(2)  ionization energies, and

(3)  electron affinities.

  1. Which of the following set of elements is written in order of their increasing metallic character?
