EasyWhat is the number of elements in periods $1$ to $7$ of the periodic table?
(N/A) The number of elements in each period is determined by the filling of orbitals $(ns, (n-2)f, (n-1)d, np)$. The distribution is as follows:
| Period | Number of Elements |
| $1$ | $2$ |
| $2$ | $8$ |
| $3$ | $8$ |
| $4$ | $18$ |
| $5$ | $18$ |
| $6$ | $32$ |
| $7$ | $32$ (Incomplete) |
