The electron configuration of boron is [He]2s2.2p1.
Cobalt electron configuration is [Ar]3d7.4s2.Cobalt(2+) electron configuration is [Ar]3d7.
Nitrogen's symbol is N. Its electron configuration is 2s, 3p.
Germanium has atomic no. 32. Its electronic configuration is 1s22s22p63s23p64s23d104p2.
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 ground state electron configuration of Lanthanum is [Xe] 5d1 6s2.
B. Rn6s25d1. Lanthanum (La) has an atomic number of 57, so the electron configuration would be [Xe] 6s25d1. The noble gas right before La on the periodic table is Radon (Rn), hence the correct electron configuration for lanthanum is Rn6s25d1.
[Xe]6s25d1
The noble gas configuration of Lanthanum (La), which has an atomic number of 57, is [Xe] 6s². This means that Lanthanum has the same electron configuration as the noble gas Xenon, followed by two additional electrons in the 6s subshell.
[Xe]6s25d1
The complete electron configuration of mendelevium is:1s22s22p63s23p63d104s24p64d104f145s25p65d105f136s26p67s2
The electron configuration of meitnerium is:1s22s22p63s23p63d104s24p64d104f145s25p65d105f146s26p66d77s2
The longhand electron configuration for sulfur is 1s2.2s2.2p6.3s2.3p4.
The electron configuration of gallium is: [Ar]3d104s24p1.
The complete electron configuration for the copper atom is 1s2 2s2 2p6 3s2 3p6 4s1 3d10.
Lanthanum has 2 valence electrons.
The noble gas configuration for Lanthanum is [Xe] 5d1 6s2. Lanthanum has 57 electrons, so the noble gas before it (Xenon - atomic number 54) has a configuration of [Xe].
