Current Question (ID: 7618)

Question:

$\text{The period and group number of the element with Z = 114 are:}$

Options:

1. $\text{8th period and 16th group}$
2. $\text{7th period and 14th group}$ (Correct)
3. $\text{14th period and 7th group}$
4. $\text{9th group and 14th period}$

Solution:

$\text{HINT: The last element of actinoid is 103, so you need to find 11th element from Actinoid.}$\n\n$\text{Explanation:}$\n\n$\text{[Rn] 5f}^{14}\text{6d}^{10}\text{7s}^2\text{7p}^2$\n\n$\text{Those with Z = 90 – 103 are f – block elements.}$\n\n$\text{10 elements with Z = 89 and Z = 104 – 112 are d – block elements, and the elements with Z = 113 – 118 are p – block elements.}$\n\n$\text{Therefore, the element with Z = 114 is the second p – block element in the 7th period.}$
