Question 2

JMINTS The first element of alkali and alkaline earth metals differs in many respects from the other members of the group be The s-block elements of the Periodic Table are those in which the last electron enters the outermost

s

-orbital. As the s-orbital can accommodate only two electrons, two groups (

1&2

) belong to the s-block of the Periodic Table. Group 1 of the Periodic Table consists of the elements: lithium, sodium, potassium, rubidium, caesium and francium. They are collectively known as the alkali metals. These are so called because they form hydroxides on reaction with water which are strongly alkaline in nature. The elements of Group 2 include beryllium, magnesium, with the exception of beryllium radium. These elements the alkaline earth metals. These are commonly known as the alkaline earth metais. These are so called because their gical the alkaline earth metals. These are so called because their and metal oxides are found in the earth's crust. Among the alkali metals sodium and potassium are lower abundances (Table 10.1). Francium is highly radioactive; its longest-lived isotope

^{223} Fr

h has a half-life of only 21 minutes. Of the alkaline earth metals calcium and magnesium rank fifth and sixth in abundance respectively in the earth's crust. Strontium and barium have much lower abundances. Beryllium is rare and radium is the rarest of all comprising only

1 0^{- 10}

per cent of igneous rocks (Table 10.2, page 299). The general electronic configuration of

s

-block elements is [noble gas] s

^{1}

for alkall metals and [noble gas]
