Class 10 Science - Chapter Metals and Non-Metals NCERT Solutions | Differentiate between metal and non-meta
Differentiate between metal and non-metal on the basis of their chemical properties.
| Metal | Non-Metal |
|---|---|
| Metals are electropositive. | Non-metals are electronegative. |
|
They react with oxygen to form basic oxides. 4Na + O2 → 2Na2O These have ionic bonds. |
They react with oxygen to form acidic or neutral oxides. C + O2 → CO2 These have covalent bonds. |
|
They react with water to form oxides and hydroxides. Some metals react with cold water, some with hot water, and some with steam. 2Na + 2H2O → 2NaOH + H2 ↑ |
They do not react with water. |
|
They react with dilute acids to form a salt and evolve hydrogen gas. However, Cu, Ag, Au, Pt, Hg do not react. 2Na + 2HCl → 2NaCl + H2 ↑ |
They do not react with dilute acids. These are not capable of replacing hydrogen. |
|
They react with the salt solution of metals. Depending on their reactivity, displacement reaction can occur. CuSO4 + Zn → ZnSO4 + Cu |
These react with the salt solution of non-metals. |
|
They act as reducing agents (as they can easily lose electrons). Na → Na+ + e- |
These act as oxidising agents (as they can gain electrons). Cl2 + 2e- → 2Cl- |
