The modern Periodic table containing first three periods in which five elements have been represented by the letters a,b,c,d,e is given and answers to above asked questions are given .
Explanation:
a)The letter that represents the alkali metal is : d .
Alkali metals (members of group 1 )
They are big in size with low ionization energy .
They always loose electrons .
This includes : Li,Na,K,Rb,Cs,Fr
b)The letter that represents inert gas: "c".
Inert gases
Their valence shell is complete .
They have stable electronic configuration .
They are least reactive .
This group includes : He,Ne,Ar,Kr,Xe,Rd
c)The bond formed between a and b is : "Covalent bond ".
Covalent Bond
It is formed when metal and non metal combine with each other .
It is formed when combining atoms show sharing of electrons .
