Question

An element Y has electronic configuration 2,8,6.

The element ‘Y’ is a ………..(metal/nonmetal/noble gas).

Answer 1

• Element is a pure substance that is made up of the same type of atoms.
• As per the octet rule: Non-Metals are those elements that contain more than 4 electrons in the outermost shell that will gain the required electrons and are called nonmetals.
• Metals that have less than four electrons in the outer shell will lose their valence electrons to get a stable noble gas configuration.
• Noble gas neither loose electrons nor will gain as their outermost shell valence electrons are complete. They are the most stable elements in a periodic table.

Thus element Y has electronic configuration 2,8,6.

The element ‘Y’ is a non-metal.
