Question

2. State the properties of metallic elements and non-metallic
elements.​

Answer 1

Answer:

Metallic Elements have free Electrons while Non Metallic donot have them.

Explanation:

Metallic elements can conduct heat and electricity while Non Metallic cannot.

Answer 2

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:)
