(a)
Interpretation:
The number of valence electrons in aluminium should be indicated.
Concept Introduction:
An outer shell electron(s) which is related with an atom and that electron(s) can take part in the creation of a
Periodic Table contains periods and groups. There are 18 groups and 7 periods in the periodic table. The vertical columns are known as groups and horizontal rows are known as periods. The numbering of periods is done as 1 to 7 from top to bottom and groups are named as 1A, 2A, 3B to 8B, 1B, 2B, 3A to 8A from left to right where A represents representative elements and B represents
In periodic table, different blocks within the periodic table correspond to the s, p, d and f sublevels. Thus, on the basis of increasing
(b)
Interpretation:
The number of valence electrons in Group 5A (15) should be indicated.
