Are all the valence electrons of cabon atoms in graphite localized to specific covalent bonds?

Are all the valence electrons of carbon atoms in graphite localized to specific covalent bonds ?

Carbon forms a large number of compounds because of its two unique properties formed many have long straight chains of carbon, branched chains of carbon or rings of carbon. In these compounds, carbon atoms may form single, double or triple covalent bonds. Compounds in which the carbon atoms are linked to each other by single bonds are called saturated carbon compounds whereas compounds having at least one carbon-carbon double or triple bond are called unsaturated carbon compounds. Compounds containing only carbon and hydrogen are known as hydrocarbons. Based on the above information, answer the following questions. ii. Give two examples of carbon compounds which have ring structure.

Give IUPAC names of first two members of hydrocarbon which contain carbon-carbon double bonds.

Is the number of valence electrons same for all these elements?

According to the electronic theory of chemical bonding, developed independently by Kossel and Lewis, the atoms of representative elements can combine either by the transfer of valence electrons from one atom to another (gaining or losing) or by the sharing of valence electrons in order to have an octet in their ______________. This is known as octet rule.

In the modern periodic table, the elements are arranged in the increasing order of their atomic number. This arrangement is based on the modern periodic law, which states that the properties of elements are a periodic function of their atomic numbers. In the modern periodic table, each column is called a group and each row is called a period. Elements within the same group show similarity and gradation in properties. This is due to the same number of electroms in the outermost shell . Based on the above paragraph, answer the following question: What is the number of valence electrons in an element of group 1 and group 18 respectively?
