State three different between metals and non metals on the basis of chemical properties?

Question

Answer

Chemical properties of metals and non metals.

METALS:-

* It donate the electrons.
* Forms Basic solution when it reacts with water.
* Turns Blue litmus to Red litmus paper.

NON-METALS:-

* It receives the electrons.
* Forms Acidic solution when it reacts with water.
* Turns Red litmus to Blue litmus paper.

Answer

¶¶ Metals

1. Oxides of metal are basic in nature.

2. Metals displace hydrogen from dilute acids.

3. Metals form chlorides which are electrovalent or ionic compound.

4. they displace hydrogen from water

¶¶ Non-Metals

1. Oxides of non-metals are acidic in nature.

2. They cannot displace hydrogen from dilute acid .

3. Non-metals form chlorides which are covalent compound

4. They cannot displace hydrogen from water .

Answer

ANSWER

Metals Non-metals Metals are electro-positive.Non-metals are electronegative.Metals reacts with oxygen to form basic oxides.
4Na + O_2 \rightarrow 2Na_2O4Na+O2→2Na2O
Non-metals react with oxygen to form neutral or acidic oxide.

C + O_2 \rightarrow CO_2C+O2→CO2

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_2O \rightarrow 2NaOH + H_22Na+2H2O→2NaOH+H2

Non-metals do not react with water.Metals react with dilute acids to form salt and H_2H2.Non-metals do not react with dilute acid and they can not displace hydrogen.Metals react as reducing agent by donating electrons.

Na \rightarrow Na^+ + e^-Na→Na++e−

Non-metals are oxidizing agents that can gain the electrons.

Cl_2 + e^- \rightarrow Cl^-Cl2+e−→Cl−

Answer

Metal and Non-Metal: Differences in Chemical Properties

Metals and non-metals are two distinct categories of elements on the periodic table that possess different chemical properties. Here, we will discuss three major differences between these two groups based on their chemical characteristics.

1. Reactivity
Metals:
- Metals tend to have a higher reactivity compared to non-metals.
- They readily lose electrons to form positive ions and are therefore good reducing agents.
- The reactivity of metals increases as you move down a group and decreases from left to right across a period on the periodic table.
- For example, alkali metals such as sodium and potassium are highly reactive and can easily react with water or air.
- Transition metals have varying reactivity, with some being highly reactive (e.g., iron) and others being less reactive (e.g., gold).

Non-Metals:
- Non-metals generally have a lower reactivity compared to metals.
- They tend to gain electrons to form negative ions and are good oxidizing agents.
- The reactivity of non-metals increases from right to left across a period and decreases as you move down a group.
- For instance, halogens like fluorine and chlorine are highly reactive non-metals that readily form compounds with metals.

2. Electronegativity
Metals:
- Metals have low electronegativity values.
- Electronegativity is the measure of an atom's ability to attract electrons towards itself in a chemical bond.
- Since metals have a tendency to lose electrons, they have low electronegativity values.
- This property makes metals more likely to form positive ions in ionic compounds.

Non-Metals:
- Non-metals have high electronegativity values.
- They have a greater ability to attract electrons, which makes them more likely to gain electrons and form negative ions in ionic compounds.
- Non-metals such as oxygen and fluorine have very high electronegativity values.

3. Acidic or Basic Nature
Metals:
- Metals generally have a basic or alkaline nature.
- They tend to form basic oxides when they react with oxygen.
- For example, sodium reacts with oxygen to form sodium oxide, which is a basic oxide and can react with water to form a basic solution (sodium hydroxide).

Non-Metals:
- Non-metals often have an acidic nature.
- They tend to form acidic oxides when they react with oxygen.
- For instance, sulfur reacts with oxygen to form sulfur dioxide, which is an acidic oxide and can react with water to form an acidic solution (sulfurous acid).

Overall, metals and non-metals exhibit notable differences in terms of reactivity, electronegativity, and acidic or basic nature. These distinctions arise from variations in their atomic properties, such as the tendency to gain or lose electrons, and influence their behavior in chemical reactions and compound formation.

Answer

Metals and non metals are different in chemichal properties
Metals:-
metals have the the power to regains its form and also known as a physical change

1. Metals are electropositive.

2. They react with oxygen to form basic oxides.

4Na+O2 ----->2Na2O

3. These have ionic bonds.

Nonmetal:-non metals can not regain its original state and also known as chemical change.

1. Non-metals are electronegative.

2. They react with oxygen to form acidic or neutral oxides.

C+O2----->CO2

3. These have covalent bonds.
