List two characteristics of covalent compounds.

If an element $X$ is placed in group $14$,what will be the formula and the nature of bonding of its chloride?

Carbon forms four covalent bonds by sharing its four valence electrons with four univalent atoms,e.g.,hydrogen. After the formation of four bonds,carbon attains the electronic configuration of:

In electron dot structure,the valence shell electrons are represented by crosses or dots.
$(a)$ The atomic number of chlorine is $17$. Write its electronic configuration.
$(b)$ Draw the electron dot structure of chlorine molecule $(Cl_2)$.

List two characteristic features of carbon which,when put together,give rise to a large number of carbon compounds.

What will be the formula and electron dot structure of cyclopentane?
