To determine the number of valence electrons for potassium (K), follow these steps:
Identify the Atomic Number: The atomic number of potassium (K) is 19. This means it has 19 electrons when neutral.
Determine the Electron Configuration: The electron configuration for potassium can be written as follows:
1s² 2s² 2p⁶ 3s¹
Count the Valence Electrons: Valence electrons are the electrons in the outermost shell of an atom. For potassium, the outermost shell is the third shell (n=3), which contains:
3s¹
Therefore, potassium has 1 valence electron.
In summary, potassium (K) has 1 valence electron.
