Question

Write the general electric configuration of the 1)d block element
2)f block element
3)noble gasses

Answer 1

Answer:

s-block elements:

They are highly reactive elements and thus occurs in combined state. On moving down the group their reactivity increases.They have good reducing characters.They generally form electropositive ion by losing 1 or 2 electrons, that’s why they are electro positive in nature.They are good conductors of heat and electricity.

p-block elements:

Most of the p-block elements show variable oxidation states.They include both metals and non-metals.They are generally covalent in nature.As move from left to right the non-metallic character of the element increases.On moving down the group metallic character increases.

d-block elements:

d-block elements show variable oxidation states.They are generally paramagnetic in nature.Their compounds are generally coloured. Those which form complex compounds.Most of the elements and their compounds acts as catalyst.

f-block elements:

They are generally heavy metals having high melting and boiling points.Their compounds are generally coloured.Variable oxidation states are generally shown by these elements.Most of Activities are radioactive.

General electronic configuration:

General electronic configuration:s-block —ns1-2

General electronic configuration:s-block —ns1-2p-block —ns2 np1- 6

General electronic configuration:s-block —ns1-2p-block —ns2 np1- 6d-block —(n -1) d1 -10 ns0-2

General electronic configuration:s-block —ns1-2p-block —ns2 np1- 6d-block —(n -1) d1 -10 ns0-2f-block —(n – 2)f0-14 (n -1) d0- 1 ns2

Thanks for the question.

Hope it helps you.
