Asked by Prakash Sengupta · 2 years ago
While studying for the NEET exam, I came across the term 'atomic number'. Why is the atomic number significant, especially for elements like Chromium (Cr)?
The atomic number is significant because it defines the identity of an element. For Chromium (Cr), the atomic number is 24, which means it has 24 protons in its nucleus. This determines its position in the periodic table and its chemical behavior.
For example, Chromium's electron configuration is [Ar] 3d5 4s1. This configuration influences its oxidation states and its ability to form various compounds, which are crucial topics for your NEET preparation.
