In the periodic table, the element with atomic number 16 will be placed in the group

Options

A. Third
B. Fourth
C. Fifth
D. Sixteenth

Answer

To determine the group in which the element with atomic number 16 is placed in the periodic table, follow these steps:

### Step 1: Identify the Element
The element with atomic number 16 is Sulfur (S).

### Step 2: Determine the Electron Configuration
The electron configuration of Sulfur can be written as:
- 1s² 2s² 2p⁶ 3s² 3p⁴

### Step 3: Count the Valence Electrons
Valence electrons are the electrons in the outermost shell. For Sulfur:
- The outermost shell is the third shell (n=3), which contains:
- 2 electrons in the 3s subshell (3s²)
- 4 electrons in the 3p subshell (3p⁴)

Thus, the total number of valence electrons = 2 (from 3s) + 4 (from 3p) = 6 valence electrons.

### Step 4: Determine the Group Number
For elements in the p-block of the periodic table, the group number can be determined using the formula:
- Group number = Number of valence electrons + 10

Since Sulfur has 6 valence electrons:
- Group number = 6 + 10 = 16

### Step 5: Conclusion
Therefore, the element with atomic number 16 (Sulfur) is placed in Group 16 of the periodic table.

### Final Answer
The correct answer is Group 16.
