SUMMARY OF METALS AND NON METALS...
Answers
Answer:
Metals: Physical properties of metals, chemical properties of metals and non-metal oxide.Hardness: Most of the metals are hard, except alkali metals, such as sodium, potassium, lithium, etc. are very soft metals. These can be cut by using a knife.
Strength: Most of the metals are strong and have high tensile strength. Because of this, big structures are made using metals, such as copper (Cu) and iron (Fe). (Except Sodium (Na) and potassium (K) which are soft metals).
State: Metals are solid at room temperature except for mercury (Hg).
Sound: Metals produce ringing sound, so, metals are called Sonorous. Sound of metals is also known as Metallic sound. This is the cause that metal wires are used in making musical instruments.Chemical Properties: Metal oxides are basic in nature. The aqueous solution of metal oxides turns red litmus blue.
Reaction of Metal oxides with Water: Most of the metal oxides are insoluble in water. Alkali metal oxides are soluble in water. Alkali metal oxides give strong base when dissolved in water.
Reaction of Sodium oxide with Water: Sodium oxide gives sodium hydroxide when reacts with water.
Metals and Non-metals
Answer:
Metals are good conductors of heat and electricity while Non metals are not.. mercury is the only metal that does 'nt conduct electricity and graphite is the only non metal which conduct electricity.
