Q
Q: What is the electronic configuration of the potassium ion (K+)?
Solution:
The potassium ion (K+) loses one electron, resulting in the configuration 1s2 2s2 2p6.
Steps: 5
Show Steps
Step 1: Identify the atomic number of potassium (K), which is 19. This means a neutral potassium atom has 19 electrons.
Step 2: Write the electronic configuration for a neutral potassium atom. It is 1s2 2s2 2p6 3s1.
Step 3: Understand that the potassium ion (K+) is formed when potassium loses one electron.
Step 4: Remove one electron from the outermost shell (3s1) of the neutral potassium configuration.
Step 5: The new electronic configuration for K+ is now 1s2 2s2 2p6, as the 3s electron is lost.
