The correct order of the atoms in terms of their `IE_(1)` is :

Options

A. `Li lt B lt Be lt C`
B. `Li lt Be lt B lt C`
C. `Li gt B gt Be gt C`
D. `Li gt Be gt B gt C`

Explanation

To determine the correct order of the atoms in terms of their first ionization energies (IE₁) for lithium (Li), beryllium (Be), boron (B), and carbon (C), we can follow these steps:

### Step 1: Understand Ionization Energy
Ionization energy is the energy required to remove the outermost electron from an atom in its gaseous state. Generally, ionization energy increases across a period (from left to right) in the periodic table due to increasing nuclear charge and decreasing atomic radius.

### Step 2: Write Electronic Configurations
Let's write the electronic configurations for each of the elements:
- **Lithium (Li)**: Atomic number 3 → Electronic configuration: 1s² 2s¹
