An element with atomic number 113 has been discovered.It will belong to which of the following block,group number,period and outershell electronic configuration?

Options

A. s-block,group 2,period 7,` 7s^2`
B. p-block,group 13,period 7, `7s^2 7p^1`
C. p-block,group 13,period 6,` 6s^2 6p^1`
D. d-block,group -12,period 6,` 5d^10 6s^2`

Answer

To determine the block, group number, period, and outer shell electronic configuration of the element with atomic number 113, we can follow these steps:

### Step 1: Identify the Block
- Elements are categorized into blocks based on their electron configurations. The blocks are:
- **s-block**: Groups 1 and 2
- **p-block**: Groups 13 to 18
- **d-block**: Transition metals (Groups 3 to 12)
- **f-block**: Lanthanides and actinides

Since atomic number 113 is greater than 112, which is the last element in the d-block, it falls into the p-block.

**Hint:** Look at the periodic table to see how elements are organized into blocks based on their electron configurations.

### Step 2: Determine the Group Number
- The element with atomic number 113 is in the p-block and specifically belongs to Group 13. This is because the p-block starts from Group 13 onwards.

**Hint:** Remember that the p-block elements start from Group 13 and go up to Group 18.

### Step 3: Identify the Period
- The period of an element corresponds to its highest principal quantum number (n). For atomic number 113, the highest principal quantum number is 7, which means it is in the 7th period.

**Hint:** The period number can be found by looking at the highest energy level of the outermost electrons.

### Step 4: Write the Outer Shell Electronic Configuration
- The outer shell electronic configuration for elements in the p-block can be represented as:
- For Group 13 elements, the outer shell configuration is typically ns² np¹.
- For element 113, the configuration will be:
- 7s² 7p¹ (since it is in the 7th period).

**Hint:** The outer shell configuration is determined by the group number and the period of the element.

### Final Answer
- The element with atomic number 113 belongs to:
- **Block:** p-block
- **Group Number:** 13
- **Period:** 7
- **Outer Shell Electronic Configuration:** 7s² 7p¹

### Summary
- **Block:** p-block
- **Group:** 13
- **Period:** 7
- **Outer Shell Electronic Configuration:** 7s² 7p¹
