Osmium
No element has this as the ground state. Gadolinium has the right number of electrons but its ground state is [Xe] 4f7 5d1 6s2. The second number in each group should be a superscript.
The element with the electron configuration 6s2 4f7 5d1 is Actinium (Ac) with atomic number 89.
The ground state electron configuration of Lanthanum is [Xe] 5d1 6s2.
The valence electron configuration of europium (atomic number 63) is [Xe] 4f7 6s2. This means that europium has 2 valence electrons in its outermost shell.
The electron configuration of the element with the symbol W (tungsten) is Xe 4f14 5d4 6s2.
The element represented is gadolinium (Gd). It has 54 electrons, with the electron configuration: [Xe] 6s2 4f7.
The noble gas configuration of europium is [Xe] 4f7 6s2. Europium typically forms the Eu2+ ion, losing its 6s2 electrons to achieve a stable octet configuration like xenon.
No element has this as the ground state. Gadolinium has the right number of electrons but its ground state is [Xe] 4f7 5d1 6s2. The second number in each group should be a superscript.
Europium
Europium is a chemical element with symbol Eu and atomic number 63 and a member of the lanthanides (f-block, [Xe] 4f7 6s2, in period 6). It is a ductile metal.
Ce: 1s22s22p63s23p64s23d104p65s24d105p66s24f2 Ce: [Xe] 6s24f2
This electron configuration is for osmium (Os).
The element with the electron configuration 6s2 4f7 5d1 is Actinium (Ac) with atomic number 89.
The element with electron configuration Xe 6s2 4f4 is Curium (Cm) with atomic number 96. It is a radioactive transuranium element that is part of the actinide series.
that would not be an element itself, but a compound containing a few different elements: xenon, sulfur, and one undiscovered element ("F" does not currently exist)
The ground state electron configuration of Lanthanum is [Xe] 5d1 6s2.
the element is tungsten with the electronic configuration Xe 4f14 5d4 6s2
