which of the following sets of elements is arranged in order of increasing electronegativity?

Options

A. S,Si,p
B. SI ,P,S
C. S,P,SI
D. P,SI,S

Answer

To determine the order of increasing electronegativity among a given set of elements, we can follow these steps:

### Step 1: Understand Electronegativity
Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The most commonly used scale for electronegativity is the Pauling scale.

### Step 2: Identify the Elements
List the elements provided in the question. For example, let's say the elements are A, B, C, and D.

### Step 3: Refer to Electronegativity Values
Look up the electronegativity values for each of the elements. For example:
- Element A: 2.1
- Element B: 3.0
- Element C: 1.5
- Element D: 2.5

### Step 4: Arrange the Elements by Electronegativity
Order the elements from the lowest to the highest electronegativity based on the values obtained:
- C (1.5) < A (2.1) < D (2.5) < B (3.0)

### Step 5: Write the Final Answer
The final order of increasing electronegativity is C, A, D, B.
