During a chemical change, matter is rearranged to produce new forms of matter. This is a result of either the sharing or transfer of electrons between different atoms. Observable evidence of a chemical change can be, but is not limited to, the formation of bubbles, a change in color or temperature, and the presence of a smell.
Sodium is in the first column of periodic table... it means the sodium has one electron in valence shell... to achieve stability it should complete octave by losing one electron or by getting seven electrons... during bond formation(either covalent or ionic) it is better to offer one electron to achieve stability... hence sodium is highly reactive...thus react with skin when placed in hand...
