Which of the following statements is true?
...Which of the following statements is true?
Metals conduct electricity while non-metals do not
Metals have high density, non-metals have low density
Metals form basic oxides, non-metals form acidic oxides
In the electro chemical series, metals are above hydrogen while non-metals are below hydrogen
Metals lose elections while non-metals gain electron during chemical reactions
Correct answer is E
- Chemical reactions in which electrons are transferred are called oxidation-reduction, or redox, reactions. Oxidation is the loss of electrons. Reduction is the gain of electrons. Oxidation and reduction always occur together, even though they can be written as separate chemical equations. -The most common reducing agents are metals, for they tend to lose electrons in their reactions with nonmetals. Option E is most appropriate.
