The maximum number of elements that can be accommodated in the sixth period are :

1.  8

2. 18

3. 32

4 16

The period and group number of the element with Z =114 are:

The atomic number of the element present in the 3rd period and 17th group of the periodic table would be -

1. 18

2. 23

3. 24

4. 17

The similarity in physical and chemical properties in a group of periodic table is due to the -

1. Same atomic number

2. Same number of valence electrons.

3. Same atomic mass

4. Same number of isotopes

The general outer electronic configuration of s, p, d , and f-block elements respectively would be :

The position of elements with an outer electronic configuration as $(n-2) f^7(n-1)d^{1}n{s}^2, n = \mathrm{6\; :}$

1. 6^th period and 10^th group.

2.  7^th period and 3^rd group.

3.  6^th period and 3^rd group.

4. 7^th period and 9^th group.

The factor that does not affect the valence electron is:
