Element number 42 Molybdenum (Mo) has the electron configuration [Kr] 5s1 4d5.
[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.
Krypton is an element with symbol Kr and atomic number 36.
The element with the electron configuration Kr 5s^2 4d^10 5p^2 is Xenon (Xe).
The element with an electron configuration of Kr 4d^6 corresponds to the element Palladium (Pd).
The element Ar 4s2 3d10 4p6 is Krypton (Kr).
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)
Technetium (Tc)Long way: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d5Short way: [Kr] 5s2 4d5
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
The noble gas core configuration of rubidium is [Kr]5s1. It is derived from the electron configuration of the noble gas krypton ([Kr] = 1s22s22p63s23p63d104s24p6), followed by the valence shell configuration of rubidium (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.
Molybdenium: (K,L,M,N,O) = 2,8,18,13,1 or: 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)
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.
If it is an element, it could be either chromium (Cr) or molybdenum (Mo). You need to know more to know which. The electronic configuration for Cr is:[Ar]3d54s1and for Mo it is[Kr]4d55s1So both elements have 5 d-electrons and 1 s-electron. I'm not sure if that what you mean however by "s1d5"...
