Answer:
C.5
Explanation:
A number of electrons present in valence shell of penultimate Shell represents the group of elements.
For s block elements: no.of group=number of valence shell electron.
p block elements: no. of group= 2 + 10 + number of valence electrons.
d block elements: no. of group= number(n-1)d electrons + number of electrons in nth shell.
Here, the differential electron is in p orbital hence, it belongs to p block
No. of group= 2+ 10 + 3=15 i.e 15th group or VA group.
Answer:
OH-
Explanation:
H2O can act as base or acid.
When H2O acts as a base the conjugate acid is H3O+
When H2O acts as an acid the conjugate base is OH-
DR is the correct answer
