The element with electronic configuration 2,8,6 is

Options

A. metallic with valency 2
B. non-metallic with valency 2
C. metalloid with valency 2
D. none of these

Explanation

To determine the element with the electronic configuration of 2,8,6, we can follow these steps:

### Step 1: Understand the Electronic Configuration
The electronic configuration given is 2,8,6. This means:
- The first shell has 2 electrons.
- The second shell has 8 electrons.
- The third shell has 6 electrons.

### Step 2: Calculate the Atomic Number
To find the atomic number, we sum the number of electrons in all the shells:
\[ 2 + 8 + 6 = 16 \]
Thus, the atomic number of the element is 16.

### Step 3: Identify the Element
Using the periodic table, we can identify the element with atomic number 16. The element with atomic number 16 is sulfur (S).

### Step 4: Determine the Nature of the Element
Sulfur is located in Group 16 of the periodic table, and it is classified as a non-metal.

### Step 5: Determine the Valency
To find the valency of sulfur, we look at the number of valence electrons. The valence electrons for sulfur are the electrons in the outermost shell, which is 6 in this case.

Since sulfur has more than 4 valence electrons, we can use the formula:
\[ \text{Valency} = 8 - \text{Valence Electrons} \]
So, for sulfur:
\[ \text{Valency} = 8 - 6 = 2 \]

### Final Answer
The element with electronic configuration 2,8,6 is sulfur (S), which is a non-metal with a valency of 2.
