Question

point out the anomalies in the position of the elements of the first period in modern periodic table​

Answer 1

Explanation:

Periodic Table Trend Anomalies. Abstract: Atomic radius is the physical size of an atom while ionization energy is the energy required to completely pull one electron away from an atom. When it comes to the periodic table, there are accepted periodic trends for both atomic radius and ionization energy.

Answer 2

Answer:

Below is the answer.

Explanation:

Periodic table is used in chemistry to describe the details i.e number of electrons in an atom, atomic radius etc of elements. The periodic table has specific trends. For example the valency increases in the first ten elements and then starts decreasing with out any change of group. Similarly Atomic radius increases down the group due to addition of electron. Such anomalies are more seen in the initial atoms of the periodic table.
