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

Solutions

Expert Solution

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.
