Question

1. xplain y alkali and alkaline earth metals cannot be obtained by chemical reduction

Answer 1

• Alkali metal and alkaline earth metals are largest sized atoms found in the periodic table.
• Due to this, their ionization energy is small. So it is easy of removal of electrons from valence shell.
• This makes these metals a strong reducing agent itself. Hence, they are not reduced by others or their chemical reduction is difficult.
