Answer:
METALLIC ELEMENTS
- easily lose valence electrons
- 1-3 electrons (usually) in the outer shell
- form basic oxides
- good reducing agents
- have low electronegativity
- solid at room temperature (except mercury)
- have metallic luster
- good conductor of heat and electricity
- typically malleable and ductile
- opaque in a thin sheet
NON METALLIC ELEMENTS
- easily share or gain valence electrons
- 4-8 electrons in the outer shell (7 for halogens and 8 for noble gases)
- form acidic oxides
- good oxidizing agents
- have higher electronegativity
- may be liquid, solid, or gas (noble gases are gases)
- do not have metallic luster
- poor conductor of heat and electricity
- usually brittle
- transparent in a thin sheet
hope this will help u:)
