Technetium (Tc)
Long way: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d5
Short way: [Kr] 5s2 4d5
The electron configuration of technetium is [Kr]4d5.5s2.
Technicium (Tc) can be found in period 5 group VII of the periodic table. It is a transition metal and so is a d-block element. Thus the electron configuration is [Kr]4d5 5s2
The atomic number for sulfur is 16. That means that its electron configuration is 1s2 2s2 2p6 3s2 3p4. This can be shortened to [Ne] 3s2 3p4, which shows you that 3s2 3p4 is how sulfur's electron configuration ends.
The electron configuration is the number of electrons in each energy level of an element. The electron configuration of Li is, 1s2 2s1. The electron configuration of F is, 1s2 2s2 2p5.
Gallium does. Atomic # 31
The electron configuration of technetium is [Kr]4d5.5s2.
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)
Pallidium
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.
Technicium (Tc) can be found in period 5 group VII of the periodic table. It is a transition metal and so is a d-block element. Thus the electron configuration is [Kr]4d5 5s2
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.
