cOUNTS TOWARDS GRADE Write electron configurations for cations Key for entering electron configuration information Key for entering orbital box information u- electron with spin "up" Enter answer on one line WITHOUT superscripts Separate each subshell with a space d = electron with spin "down". Always start with spin up. Leave empty orbitals blank. Example: Neon (1s22s22p6) should be entered as 1s2 2s2 2p6 Write the electron configurations for the following ions using spectroscopic (spdf) and orbital box notation. (a) K+ Full electron configuration - (do not use noble gas notation) Orbital box notation: 1s 2 3s (b) Ti2+ Noble gas electron configuration - Orbital box notation: 3d Check & Submit Answer Show Approach

Respuesta :

The full form of the electronic configurations are :

a) K⁺ = 1s² 2s² 2p⁶ 3s² 3p⁶

b) Ti⁺² = 1s² 2s² 2p⁶ 3s² 3p⁶ 3d²

a) the electronic configuration of potassium , K with atomic number 19 is as follows :

K = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹

K⁺ ion losses one electron from the outermost shell.

K⁺ = 1s² 2s² 2p⁶ 3s² 3p⁶

b) the electronic configuration of titanium , Ti with atomic number 22 is :

Ti =  1s² 2s² 2p⁶ 3s² 3p⁶ 3d² 4s²

Ti⁺² = 1s² 2s² 2p⁶ 3s² 3p⁶ 3d²

Thus, The full form of the electronic configurations are :

a) K⁺ = 1s² 2s² 2p⁶ 3s² 3p⁶

b) Ti⁺² = 1s² 2s² 2p⁶ 3s² 3p⁶ 3d²
