Findout the maximum number of electrons in outermost shell for s,p,d,f block elements.
Answers
Answer:
2,8,2,2
Explanation:
The trick is in the language of question, actually it asks for electrons in outermost shell.
the common configuration for a d-block and f-block elements says that the outermost shell contains just an s orbital. the d-orbital is present in penultimate shell and f in anti penultimate.
But the case is not so in p block, the outermost shell otself has p orbital.
Hope you understood!
Answer:
s-block : 2 electrons
p-block : 6 electrons
d-block : 10 electrons
f-block : 14 electrons
Explanation:
S, p, d and f blocks are groups of elements in the periodic table with their a definite subshell.
S,p,d and f are subshells. Each subshell contains a number of orbitals.
Orbitals are spaces around the nucleus that have high probability of electrons. Each orbitals can contain a maximum of only 2 electrons.
S block elements have one orbital. Therefore maximum electrons contained in it is 2 electrons.
P block elements have three orbitals. Therefore maximum electrons contained in it is 6 electrons.
D block elements have 5 orbitals. Therefore maximum electrons contained in it is 10 electrons.
F block elements have seven orbitals. Therefore maximum electrons contained in it is 14 electrons.
