The atomic radii of three elements A, B and C of a periodic table are

1.	The atomic radii of three elements A, B and C of a periodic table are 186 pm, 104 pm and 143 pm respectively, Giving a reason, arrange these elements in the increasing order of atomic numbers in the period.
Answer» Order of atomic number of element A<C<B. Because atomic size generally decreases along a period, So B has the highest atomic number followed by C and A

The atomic radii of three elements A, B and C of a periodic table are 186 pm, 104 pm and 143 pm respectively, Giving a reason, arrange these elements in the increasing order of atomic numbers in the period.

Answer»

Order of atomic number of element

A<C<B.

Because atomic size generally decreases along a period, So B has the highest atomic number followed by C and A
