Solution Steps

Step 1: Understand the Question

The question asks which group of elements have six electrons in the highest-energy \( p \) sublevel in their ground state. This refers to the electron configuration of elements.

Step 2: Recall Electron Configuration

The \( p \) sublevel can hold a maximum of six electrons. Elements with a completely filled \( p \) sublevel in their highest energy level are known as noble gases. These elements have a stable electron configuration.

Step 3: Identify the Correct Group

Given the options:

  • E) Halogens: These have five electrons in the \( p \) sublevel.
  • D) Alkali metals: These have one electron in the \( s \) sublevel.
  • A) Noble gases: These have six electrons in the \( p \) sublevel.
  • B) Transition metals: These have electrons in the \( d \) sublevel.
  • C) Alkaline earth metals: These have two electrons in the \( s \) sublevel.

The noble gases are the elements that have six electrons in the highest-energy \( p \) sublevel.

Final Answer

\(\boxed{\text{A) noble gases}}\)
