Q5. Sodium is a metal & sulfur is a non- metal. Explain why we classify them this way.
Metals- conduct electricity, lose electrons to complete valence shell.
Non- metals- insulator of electricity, gain electrons to complete valence shell.

Sodium, is a conductor of electricity & it lose onelectrons to omplete the valence shell to make it stable. Hence, sodiuis a metal.
Sulfur, is insulatorofelectricity, & it gain teo electrons to complete the valence shell to make it stable. Hence, sulfur is a non- metal.

what we could have been, 23:49.
