The correct Answer is:
To determine the place of the element with atomic number 31 in the modern periodic table, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Element**: The element with atomic number 31 is Gallium (Ga). 2. **Determine the Block**: In the modern periodic table, elements are divided 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 Gallium is located in Group 13, it belongs to the P block. 3. **Locate the Period**: The periodic table is also organized into periods (horizontal rows). Gallium is in the fourth period of the periodic table. 4. **Conclusion**: Therefore, the element with atomic number 31 (Gallium) is located in the P block and is part of the fourth period. ### Final Answer: The place of the element with atomic number 31 is in the **P block** of the periodic table. ---

In the modern periodic table, the period indicates the value of (a) atomic number (b) atomic mass (c) principal quantum number (d) azimuthal quantum number.

In the modern periodic table, elements are arranged in order of increasing atomic numbers, which is related to the electornic configuration. Depending upon the type of orbitals receiving the last electron, the elements in the periodic table have been divided into four blocks, s, p,d and f. The modern periodic table consists of 7 periods and 18 groups. Each period begins with the filling of a new energy shell. in accordance with the Aufbau principal, the seven periods (1 to 7) have 2,8,8,18,18,32 and 32 elements respectively. The seventh period is still incomplete. To avoid the periodic table being too long, the two series of f-block elements, called lanthanoids and actinoids, are placed at the bottom of the main body of the periodic table Which of the element whose atomic numbers are given below, cannot be accommodated in the present set up of the long form of the periodic table ?
