Question Question 6
Differentiate between metals and non-metals with reference to –
(a) number of electrons in outer or valence shell
(b) formation of cation and anion
(c) reaction with dilute acids
| S. No. | Chemical Property | Metals | Non-metals |
|---|---|---|---|
| (a) | No.of electrons in outer shell | Metals have 1, 2 or 3 electrons in the outer or valence shell. | Non-metals have 4, 5, 6 or 7 electrons in the outer or valence shell. |
| (b) | Formation of cation and anion | Metals lose or donate valence electrons and form cations. | Non-metals accept valence electrons and form anions. |
| (c) | Reaction with acids | Metals react with dilute acids to give hydrogen gas. | Non-metals do not react with dilute acids to give hydrogen gas. |
