There is no noble gas shorthand for hydrogen. Its electron configuration is simply 1s1.
[Ar] 3d2 4s2
Titanium is not a noble gas.
[Kr] 4d10 5s2 5p3
[Ar] 3d2 4s2
[He] 2s2 2p1
[Xe] 4f14 5d2 6s2
The chemical symbol is As. The atomic number is 33.
[Ne]3s23p3
[Kr] 4d10 5s2 5p3
[Ar] 3d2 4s2
[He] 2s2 2p1
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.
If technitium loses 7 electrons, then it will have a noble gas electronic configuration.
[Xe] 4f14 5d2 6s2
The chemical symbol is As. The atomic number is 33.
Nothing because krypton is an inert/noble gas.
[Xe] 4f14 5d10 6s2 6p2
(Xe)6s24f145d4
Yes it is possible to write the noble gas configuration of all elements, though it is not possible to list all of them here.
