What element of next-larger Z has chemical properties similar to those of oxygen?
a)Scandium
b)Aluminum
c)Magnesium
d)Sulphur
e)Boron
Give the ground-state electron configuration of this element.
a) 1s22s22p3
b)1s22s22p53s
c)1s22s22p63s23p3
d)1s22s22p63s23p4
1) In periodic table oxygen and sulphur are in same group and their chemical properties are similar.
So option D is correct.
2) Sulphur has 16 electrons, so electronic configuration is
1s22s22p63s23p4
So option D is correct.
