Metals and NonMetals Class 10 Notes Science Chemistry

Aluminium and copper metals are good conductor of heat. When exposed to air, these develop a layer of oxide. This makes it resistant to further corrosion. Calcination: i The ore is heated is absence of air. Roasting: i The ore is heated in the presence of air. In iconic compounds, ions are joined together due to powerful electrostatic forces, therefore, considerable energy is required to separate these ions and break the lattice.

Metals and Non-metals Class 10 Notes

Elements are classified broadly into two categories on the basis of properties: Metals: Iron, Zinc, Copper, Aluminium etc. Apart from metals and non-metals some elements show properties of both metals and non — metals, e. Silicon, Arsenic, Germanium.

Metals and Non-metals Class 10 Notes Science Chapter 3

A more reactive metal placed higher in the reactivity series can displace the less reactive metal from the solution of its salt. Question 1 What are amphoteric oxides? Metals and non metals: Properties of metals and non-metals, reactivity series, Formation and properties of ionic compounds, Basic metallurgical processes, corrosion and its prevention. Extracting Metals Low in the Activity Series. Metals react with water to form metal oxides or metal hydroxides and. Many metals form ionic bonds when they react with non-metals. It is useful to place carbon and hydrogen into the reactivity series because these elements can be used to extract metals.

Metals: Physical properties of metals, chemical properties of metals and non-metal oxide. Metals are the elements that conduct heat and electricity and are malleable and ductile. Metals are the elements which form positive ions by losing electrons. Thus, metals are known as Electropositive Elements. Chemical Properties of Metals 1. Reaction with oxygen: Most of the metals form respective metal oxides when reacting with oxygen.

 - Эдди! - крикнул.  - Хватит валять дурака. Какой-то тип разыскивал Меган.

 - Я… я не понимаю. - Я не могу, - повторила.  - Я не могу выйти за тебя замуж.  - Она отвернулась. Ее плечи подрагивали.
