The element Ar 4s2 3d10 4p6 is Krypton (Kr).
Krypton is an element with symbol Kr and atomic number 36.
[Kr] 5s1 4d5Mo is an exception to the usual rules of electron configuration. You would think that the configuration would be[Kr] 5s2 4d4But Mo is more stable with and extra electron in it's d orbital, rather than it's s orbital.
[Kr]5s2 4d10 5p4 is Te (tellerium).
'K' is potassium . The 'K' comes from the Latin name 'Kalium'.
Molybdenium: (K,L,M,N,O) = 2,8,18,13,1or:Mo, complete electron configuration: [1s2, 2s2 2p6, 3s2 3p6 3d10, 4s2 4p6] 4d5, 5s1 shorthand: (Kr),5s1,4d5(It is a 4d-block 'transition' element, atom no.42)
Molybdenum's electon configuration is [Kr] 5s1 4d5 this is because all elements want to be half-full or full. so the 2nd electron in the 5s2 moves to make the 4d4 complete so it turns to 5s1 4d5....making Mo half-full and stable.
The condensed electron configuration of rubidium is [Kr] 5s1 in the 1st group of period V
[Kr] 4d7 5s1
Rubidium has an atomic number of 37, making it an alkali metal. This means that its last shell is an s with only one electron. The full notation is [Kr] 5s1.
Definition: A noble gas core is an abbreviation in an atom's electron configuration where the previous noble gas's electron configuration is replaced with the noble gas's element symbol in brackets. ... This is the noble gas core notation of sodium.
