identify whether longhand notation or noble - gas notation was used in each case below. potassium (k): 1s²2s²2p⁶3s²3p⁶4s¹\nlonghand notation\nnoble - gas notation
Answer
Brief Explanations:
Longhand notation lists all the electron - occupied orbitals starting from the lowest energy level. Noble - gas notation uses the symbol of the nearest noble gas with a lower atomic number to represent the core electrons. The given electron configuration of potassium ($1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{1}$) lists all the orbitals without using a noble - gas symbol for the core electrons.
