Potassium is a chemical element with atomic number 19 (number of electrons is 19).
Electron configuration of potassium is: ₁₉K 1s²2s²2p⁶3s²3p⁶4s¹.
Potassium is the alkali metal and has a single valence electron in the outer electron shell.
Answer: The element having given configuration is potassium.
Explanation:
Electronic configuration tells us about the number of electrons that are present in an atom. It also determines the atomic number of an element.
We are given:
Electronic configuration = [tex]1s^22s^22p^63s^23p^64s^1[/tex]
Total number of electrons in the given element = (2 + 2 + 6 + 2 + 6 + 1) = 19
Element having atomic number '19' is potassium
Hence, the element having given configuration is potassium.
