The size of atoms in Group 18 get larger down the group. This is caused by
the increase in the number of electrons
the decrease in melting point and boiling point of the elements
the increase in solubility rate in water
the increase in the number of shells filled with electrons
During a chemical reaction, every alkali atom in Group 1
releases one valence electron to achieve duplet or octet electron arrangement
releases two valence electrons to achieve duplet or octet electron arrangement
releases three valence electrons to achieve duplet or octet electron arrangement
releases four valence electrons to achieve duplet or octet electron arrangement
