Question

Write any two chemical difference between metal and nonmetal

Answer 1

Answer:

Metals and Nonmetals are the elements present around us. So, it is important to know whether a particular element is a metal or nonmetal. Materials can be divided into metals and nonmetals. The characteristic feature of metals like copper and aluminium is a high electrical and thermal conductivity, while nonmetals such as phosphorus metal and sulfur are insulators. Elements are distinguished as above based on their properties.

metal:-

Majority elements in the periodic table are metals. This includes alkali metals, transition metals, lanthanides, actinides, and alkaline earth metals. Metals are separated by nonmetals on a periodic table through a zigzag line starting from carbon, till radon. The elements between the two are phosphorus, selenium, and iodine.

These elements and elements right to them in the periodic table are nonmetals. Elements present just to the left of the line are termed as semimetals or metalloids. These will have the combined properties of both metals and nonmetals.

Non Metal:-

Very few elements in the periodic table are nonmetals. These are present on the right-hand side in the periodic table. Elements that come under nonmetals are sulfur, carbon, all halogens, phosphorus, hydrogen, oxygen, selenium, nitrogen, and noble gases.

In the periodic table, non-metals are located left of the halogens and to the right of the metalloids. Since noble gases and halogens are also nonmetals, these elements are often referred to as non-metals.

.

Explanation:-

Metals lose electrons to become positive ions. The elemental metals bond using metallic bonding which uses a sea of electrons to bond unlimited numbers of atoms together. Most elements are metals. magnesium, iron, silver are examples.

Metals have low electronegativity and want to lose electrons.

Non metals gain electrons to become negative ions. The elemental nonmetals bond using covalent bonds. There are fewer nonmetals that metals. The noble gases, Oxygen, Nitrogen are examples.

Nonmetals have high electronegativity and want to gain electrons.

Metalloids can go either direction becoming either positive or negative. There are very few metalloids. examples are Carbon, Silicon.

Answer 2

Explanation:

Metals are electro-positive. Non-metals are electronegative.

Metals reacts with oxygen to form basic oxides.

4Na+O

2

→2Na

2

O

Non-metals react with oxygen to form neutral or acidic oxide.

C+O

2

→CO

2

Metal oxides and hydroxides bonds have ionic bonds. Non-metal oxides and hydroxides have covalent bonds.

Metals react with water to form hydroxide and hydrogen.

2Na+2H

2

O→2NaOH+H

2

Non-metals do not react with water.
