Question

what is the lewis symbol for k+? select the correct answer below: o k+ o :k+ o ·k+

Explanation:

Step1: Recall Lewis symbol concept

Lewis symbols show valence electrons as dots around element symbol.

Step2: Analyze potassium ion

Potassium (K) has atomic number 19. Its electron - configuration is [Ar]4s¹. K⁺ is formed when K loses its one valence electron in the 4s orbital. So, there are no valence electrons left for K⁺. The Lewis symbol for K⁺ is just the element symbol with the charge sign, which is K⁺.

Answer:

K⁺
