Question

explain the chemical properties of both metals and non metals
​

Answer 1

Answer:

Explanation:

Metals                                                                   Nonmetals

These are very hard except sodium      These are soft except diamond

These are malleable and ductile       These are brittle and can breakdown into pieces

These are shiny                                These are non-lustrous except iodine

Electropositive in nature                         Electronegative in nature

Answer 2

Answer: Chemical properties of metals choose the one u feel is best

• The density of metals is usually high.
• Metals are malleable and ductile.
• Metals form an alloy with other metals or non – metals.
• Some metals react with air and corrode. For e.g. Iron.
• Metals are good conductors of heat and electricity. Lead is an exception.
• Generally, metals are in a solid-state at room temperature. Except for Mercury. Mercury is in a liquid state.
• Many metals produce metal oxide by burning in the oxygen of the air. Highly reactive metals react violently when they’re burnt in oxygen.
• Metals like sodium and potassium are stored in oil as they react with air in seconds. They’re highly reactive metals.
• Less reactive metals like gold, silver, platinum, etc do not tarnish easily. They stay shiny and lustrous.
• Metals produce metal oxide and hydrogen gas while reacting with water.
• Soluble metal oxides dissolve in water and create metal hydroxide.
• Not all metals react with water. However, highly reactive metals like sodium and potassium react with water violently and an exothermic reaction takes place where the hydrogen immediately catches fire.
• Salt and hydrogen are produced when a metal reacts with an acid.
• Generally, a metal displaces a less reactive metal in a metal salt solution.

                 Chemical properties of non-metals

• Nonmetals are poor conductors of heat and electricity. Graphite and Gas carbon are exceptions.

• Unlike metals, nonmetals aren’t malleable and ductile.

• Nonmetals react more with metals than with nonmetals.

• Usually, nonmetals react with other nonmetals at high temperatures.

• Most nonmetals do not react with air at room temperature.

• White phosphorus is the only nonmetal that reacts with air to form its oxide by burning.

• Usually, nonmetals do not react with water. Except for Chlorine, chlorine dissolves in water to form an acidic solution.

• Nonmetals have a low density.

• They do not form alloys. However, nonmetals like carbon, silicon, and phosphorous.

• Nonmetals exist in all states of matter at room temperature.

• Different nonmetals have different reactions.

• Chlorine is the most reactive metal in the halogen family i.e. Chlorine (Cl), Bromine (Br), Iodine (I), and Fluorine (F). The reactivity order of the halogen family is Cl > Br > I. Therefore, Chlorine (Cl) can displace Bromine (Br) and Iodine (I) from solutions of bromides (NaBr) and Iodides (NaI).

• Ionic solids are formed when nonmetals with high electronegativity react with alkali and alkaline earth metals.
