Options

A. Carbon family , `[Rn]5f^(14),6d^(10),7s^(2)7p^2`
B. Oxygen family , `[Rn]5f^(14),6d^(10),7s^(2)7p^4`
C. Nitrogen family , `[Rn]5f^(14),6d^(10),7s^(2)7p^6`
D. Halogen family , `[Rn]5f^(14),6d^(10),7s^(2)7p^5`

Answer

To determine the group and electronic configuration of the element with atomic number Z = 114, we can follow these steps:

### Step 1: Identify the Element
The element with atomic number 114 is known as Flerovium (Fl).

### Step 2: Determine the Group
Flerovium (Fl) is located in Group 14 of the periodic table, which is also known as the Carbon family. This group includes elements like carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and Flerovium (Fl).

### Step 3: Find the Electronic Configuration
To find the electronic configuration, we start from the nearest noble gas, which is Radon (Rn) with an atomic number of 86. The electronic configuration of Radon is:

\[ \text{Rn: } [Xe] 4f^{14} 5d^{10} 6s^{2} 6p^{6} \]

Now, we need to add the remaining electrons to reach atomic number 114:

- Radon has 86 electrons.
- We need to add \( 114 - 86 = 28 \) electrons.

Following the order of filling orbitals (Aufbau principle):

1. **6d orbitals** can hold up to 10 electrons.
2. **7s orbitals** can hold up to 2 electrons.
3. **7p orbitals** can hold up to 6 electrons.

Adding these up:

- 6d: 10 electrons
- 7s: 2 electrons
- 7p: 6 electrons

Now, we can sum these:

\[ 86 + 10 + 2 + 6 = 114 \]

### Final Electronic Configuration
Thus, the electronic configuration of Flerovium (Z = 114) is:

\[ [Rn] 5f^{14} 6d^{10} 7s^{2} 7p^{2} \]

### Summary
- **Group**: 14 (Carbon family)
- **Electronic Configuration**: \[ [Rn] 5f^{14} 6d^{10} 7s^{2} 7p^{2} \]
