In Lother Meyer's curve, the element on the peak of curve will be

Options

A. F
B. Na
C. Mg
D. Ne

Answer

To solve the question regarding which element is at the peak of Lothar Meyer's curve, we can follow these steps:

### Step 1: Understand Lothar Meyer's Curve
Lothar Meyer's curve is a graphical representation that plots the atomic volume of elements against their atomic mass. In this curve, the peaks represent the elements with the highest atomic volume at given atomic masses.

**Hint:** Familiarize yourself with the concept of atomic volume and how it varies with atomic mass.

### Step 2: Identify the Position of Elements
In the context of the curve, alkali metals are known to be located at the peaks. This is because alkali metals have relatively high atomic volumes compared to other elements in their respective periods.

**Hint:** Remember that alkali metals include elements like Lithium (Li), Sodium (Na), Potassium (K), etc.

### Step 3: Analyze the Given Options
The options provided are:
1. Fluorine (F) - a halogen
2. Sodium (Na) - an alkali metal
3. Magnesium (Mg) - an alkaline earth metal
4. Neon (Ne) - a noble gas

From the analysis, we can see that Sodium is the only alkali metal among the options.

**Hint:** Recall the classification of elements into groups such as alkali metals, alkaline earth metals, halogens, and noble gases.

### Step 4: Conclusion
Since alkali metals are at the peak of the Lothar Meyer curve, the element on the peak of the curve will be Sodium (Na).

**Final Answer:** Sodium (Na) is the element at the peak of Lothar Meyer's curve.
