Why sodium is metal and carbon non metal

 U can write the properties af metals which sodium itself exists as:

To understand why sodium is metal and carbon is non metal you have to understand what is the definetion of metal...metals are generally charecterized by high electric conductivity, form basic oxides and can readily lose an electron to form ionic bond. Since Na. has only single electron in its outer orbit ..it can easily release its outer electron to achieve inert gas configuration and forms ionic bond. Whereas carbon has 4 electron in its outer orbit and its really difficult to release 4 electron so they form a covalent bond and hence non mettalic in nature.

If you watch the periodic table given in school chemistry book, then you may notice that Sodium (Na) is mentioned towards the left side and Carbon is mentioned towards the right of the table.

Now, since Sodium falls under the category of 1A in table, hence it is a metal.

However, note that all elements on the right side of the periodic table are non metals. The only exceptions are Boron(B), Silicon(Si), Arsenic(As), Tellurium(Te), and Astatine(At), all of which are metalloids; as well as the currently un-named elements, (Uub, Uut, Uuq, Uup, Uuh.) are considered "poor metals."

Hence, Carbon is a NON-METAL.

Hope answered your question.

The elements which give their electrons to become stable can be considered as metals. Since the valency of sodium is 11 and its electronic configuration is 2,8,1 therefore to become stable it gives its one electron and so we can say that sodium is a metal. The valency of carbon is 6 and its electronic configuration is 2,4 and to become stable it shares its 1 electron with 4 other carbon atoms to form covalent bond and so it can be considered as a non metal.

 sodium is metal

Why is sodium a metal?

• It is a good conductor of heat and electricity.
• It is malleable i.e. it can drawn into thin sheets.
• It is ductile i.e. it can be drawn into thin wires.
• It is lustrous/shiny.
• It is sonorous.
• They are hard

Why carbon is a non-metal?

• It is not a good conductor of heat and electricity.
• It is not malleable i.e. it cannot drawn into thin sheets.
• It is not ductile i.e. it cannot be drawn into thin wires.
• It is not lustrous/shiny.
• It is not sonorous.
• It is soft.

because it is malleable
