Atomic mass gets bigger when it goes down since the protons are inceasing.
Beryllium has the lowest atomic mass in group 2 of the periodic table.
Indium in the periodic table: group 13, period 5, atomic number 49.
Down a group, the atomic radius increases as the number of shells or energy levels increases.
The atomic no. of Lawrencium is 103 and it is an actinide and is placed separately from the periodic table.

Boron is located in Group 13 (formerly Group IIIA) and Period 2 of the periodic table. It has an atomic number of 5.
Aluminum is a metal in Group 13, and with atomic number 13 on the periodic table. Iron is a transition metal in Group 8, and with atomic number 26 on the periodic table.
The atomic no. of Lawrencium is 103 and it is an actinide and is placed separately from the periodic table.
The atomic radius decreases.
Yes. The atomic radius increases down the group. This is because number of shells increases down the group.
