Question

an element M has the electronic configuration 2,8,8,1 . on the basis of electronic configuration, answer the following:-
(i) does this element form acidic or basic oxide?
(ii) is it expected to be malleable and ductile or not?
(iii) will this element displace hydrogen from dilute acids?
(iv)is the element expected to be good conductor of electricity or not?
(v) M represent which element?​

Answer 1

Answer:

i)It forms a basic oxide because the element is a metal and metals form a basic oxide

ii) it is expected to be malleable and ductile because it is a metal

iii) Yes because it is a highly reactive metal

iv) yes it will be a good conductor of electricity because it is a metal

v) M - Potassium

Explanation:

i)It forms a basic oxide because the element is a metal and metals form a basic oxide

ii) it is expected to be malleable and ductile because it is a metal

iii) Yes because it is a highly reactive metal

iv) yes it will be a good conductor of electricity because it is a metal

v) M - Potassium
