HOW MANY VALENCE ELECTRONS ARE PRESENT IN AN ALKALIE METAL?
 

Dear Student,

Please find below the solution for your asked query-

• Alkali metals are the elements of group I of the periodic table. These include Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Caesium (Cs), and Francium (Fr).
• All these elements are metals and contain one electron in their valence shell.
• These are highly electropositive and readily lose an electron.
• The metals are known for their high reactivity and hence do not occur in nature in the free state, but in the combined state in the form of halides, oxides, nitrates, etc.
• The atomic radii of alkali metals are the largest in their respective periods.
