Atomic shorthand uses the noble gas before the element in question
Answer: Cu: [Ar]4s[1]3d[10]
Explanation: Copper Cu is an anomaly. Logically we would write 4s[2]3d[9] but for Cu, having the d sub level full is more stable than having the s sub-shell full and the d sub-shell less than full. Chromium also has this anomaly, and is written [Ar]4s[1]3d[5]
The ground-state electron configuration for copper (Cu) using noble-gas shorthand is Ar 3d10 4s1.
The shorthand electron configuration of aluminum is [Ne] 3s^2 3p^1, where [Ne] represents the electron configuration of the noble gas neon. This shorthand notation is used to show the core electrons before the valence electrons in the electronic configuration of an element.
2.3!<-----wrong shorthand electron configuration for Boron (B on the periodic table) is [He] 2s2 2p1 because Shorthand means building on the last noble gas element. So put the closest Noble gas element before this one and then the new addition.
