Answer 2

Symbol for the element in period 2, group13 is B.

• The element at the position of period 2 and group 13 is boron, which is written as B, which is a metalloid.
• In period 2, the number of shells filled with electrons of all the elements is 2.
• Group 13 is characterised by the number of valence electrons in the outer shell of all the elements present in the group being the same. The number of valence electrons for boron and rest of the elements for group 13 is 3.
