Provide the names,symbols,and electronic configurations of the elements in the $1^{st}$ group.

(N/A) Elements in the same vertical column or group have similar valence shell electronic configurations,the same number of electrons in the outer orbitals,and similar chemical properties. The group $1$ elements (alkali metals) have a general valence shell electronic configuration of $ns^{1}$. The details are provided in the table below:Thus,it is evident that the properties of an element have a periodic dependence upon its atomic number.

Element (Atomic number)	Symbol and Electronic configuration
Lithium $(3)$	$Li: [He] 2s^{1}$
Sodium $(11)$	$Na: [Ne] 3s^{1}$
Potassium $(19)$	$K: [Ar] 4s^{1}$
Rubidium $(37)$	$Rb: [Kr] 5s^{1}$
Cesium $(55)$	$Cs: [Xe] 6s^{1}$
Francium $(87)$	$Fr: [Rn] 7s^{1}$
