Which of the following pairs would have a larger size? Explain.
`KorK^(+)`

Explanation

To determine which of the two species, K (potassium atom) or K⁺ (potassium ion), has a larger size, we can analyze the concepts of atomic size and effective nuclear charge. Here’s a step-by-step solution:

### Step 1: Understand Atomic Size
Atomic size refers to the distance from the nucleus to the outermost shell of electrons. The size of an atom can be influenced by the number of electrons and the effective nuclear charge (the net positive charge experienced by electrons in the outer shell).

**Hint:** Remember that atomic size is influenced by both the number of electrons and the effective nuclear charge.

### Step 2: Compare K and K⁺
