Question

write all chemical Eq n related to chemical properties of metal and non metal​

Answer 1

Answer:

Metals are electropositive elements that generally form basic or amphoteric oxides with oxygen. Other chemical properties include:

Electropositive Character: Metals tend to have low ionization energies, and typically lose electrons (i.e. are oxidized) when they undergo chemical reactions They normally do not accept electrons. For example:

Alkali metals are always 1+ (lose the electron in s subshell)

Alkaline earth metals are always 2+ (lose both electrons in s subshell)

Transition metal ions do not follow an obvious pattern, 2+ is common (lose both electrons in s subshell), and 1+ and 3+ are also observed

Na0→Na++e−

Mg0→Mg2++2e−

Al0→Al3++3e−

Compounds of metals with non-metals tend to be ionic in nature. Most metal oxides are basic oxides and dissolve in water to form metal hydroxides:

Na2O(s)+H2O(l)→2NaOH(aq)

CaO(s)+H2O(l)→Ca(OH)2(aq)

Metal oxides exhibit their basic chemical nature by reacting with acids to form metal salts and water:

MgO(s)+HCl(aq)→MgCl2(aq)+H2O(l)

NiO(s)+H2SO4(aq)→NiSO4(aq)+H2O(l)

Chemical Properties of Nonmetals

Non-metals have a tendency to gain or share electrons with other atoms. They are electronegative in character. Nonmetals, when reacting with metals, tend to gain electrons (typically attaining noble gas electron configuration) and become anions:

3Br2(l)+2Al(s)→2AlBr3(s)

Compounds composed entirely of nonmetals are covalent substances. They generally form acidic or neutral oxides with oxygen that that dissolve in water to form acids:

CO2(g)+H2O(l)→H2CO3(aq)carbonic acid

As you may know, carbonated water is slightly acidic (carbonic acid).

Nonmetal oxides can combine with bases to form salts.

CO2(g)+2NaOH(aq)→Na2CO3(aq)+H2O(l)
