Where on the blank outline of the periodic table do elements that meet the following descriptions appear? (c) Elements with electrons whose largest principal quantum number is n = 4

Verified step by step guidance

1. Identify the elements with the largest principal quantum number n = 4. These elements are located in the 4th period of the periodic table.
2. Locate the 4th period on the periodic table. This is the fourth row from the top.
3. Mark the elements in the 4th period. These elements include those in groups 1 to 18.
4. Verify the positions of the elements in the 4th period. They should span from potassium (K) to krypton (Kr).
5. Ensure that the elements with n = 4 are correctly identified and marked on the periodic table outline.

Key Concepts

Principal Quantum Number (n)

The principal quantum number (n) indicates the main energy level of an electron in an atom. It is a positive integer that determines the size and energy of the orbital where the electron resides. For n = 4, electrons are found in the fourth energy level, which can accommodate a maximum of 32 electrons across various sublevels (s, p, d, f).

Periodic Table Structure

The periodic table is organized by increasing atomic number and groups elements with similar properties. Elements are arranged in rows (periods) and columns (groups), where each period corresponds to a principal quantum number. Elements with the same n value are found in the same row, making it easier to identify their properties and relationships.

Electron Configuration

Electron configuration describes the distribution of electrons in an atom's orbitals. For elements with n = 4, the configurations will include electrons in the 4s, 4p, 4d, and possibly 4f orbitals. Understanding electron configuration is crucial for predicting chemical behavior and the placement of elements in the periodic table.
