Question

Name any 10 metals and any 10 nonmetals.

Answer 1

Metals:

• Metals are a group of substances distinguished by strong electrical and thermal conductivity, as well as malleability, ductility, and high light reflectance.
• Metals are naturally occurring compounds under the Earth's surface.
• The majority of metals are lustrous or glossy.
• Metals are inorganic, which implies they are formed of nonliving components.
• Examples of metals are:
  • Lithium ($\mathrm{Li}$)
  • Magnesium ($\mathrm{Mg}$)
  • Aluminum ($\mathrm{Al}$)
  • Titanium ($\mathrm{Ti}$)
  • Iron ($\mathrm{Fe}$)
  • Cobalt ($\mathrm{Co}$)
  • Nickel ($\mathrm{Ni}$)
  • Copper ($\mathrm{Cu}$)
  • Zinc ($\mathrm{Zn}$)
  • Silver ($\mathrm{Ag}$)

Non-metals:

• Non-metals are those that lack all metallic properties.
• They are excellent heat and electricity insulators.
• They are usually gases and occasionally liquids.
• Non-metals are elements that absorb or acquire electrons to generate negative ions.
• Nonmetals often have four, five, six, or seven electrons in their outermost shell.
• Examples of non-metals are:
  • Hydrogen ($\mathrm{H}$)
  • Helium ($\mathrm{He}$)
  • Iodine ($\mathrm{I}$)
  • Argon ($\mathrm{Ar}$)
  • Oxygen ($\mathrm{O}$)
  • Neon ($\mathrm{Ne}$)
  • Nitrogen ($\mathrm{N}$)
  • Carbon ($\mathrm{C}$)
  • Sulphur ($\mathrm{S}$)
  • Bromine ($\mathrm{Br}$)
