Describe briefly Mendeleev's periodic table along
with its merits.

Explanation

### Step-by-Step Text Solution:

**1. Introduction to Mendeleev's Periodic Table:**
- Mendeleev's periodic table is based on the periodic law, which states that the physical and chemical properties of elements are a periodic function of their atomic weights. This means that when elements are arranged in order of increasing atomic weight, their properties exhibit a recurring pattern.

**2. Arrangement of Elements:**
- Mendeleev grouped elements with similar properties together. He organized the elements into rows and columns, creating a table format. He also left blank spaces in the table for elements that were not yet discovered, predicting that these elements would be found in the future.
