How many unpaired electrons are predicted for the ground state of Tantalum?
Two
Which element has 45 electrons in its ground state?
Rhodium
What is the symbol of the first element to have an electron in the 4d sublevel in its ground state?
The element is Yttrium, with the symbol Y
What element glows yellow when it's electrons fall into the ground state?
I guess Sodium.
How many unpaired electrons are predicted for the ground state configuration of bi answers possibilities are 1 6 0 2 3 OR 4?
3
What elements has a ground-state electron configuration different from the predicted one?
There are many elements among the transitional elements which has the electron configuration differed than predicted. Such element with the lowest atomic number is chromium.
Why is an iron atom a different element than a sodium atom?
An iron atom is a different element than a sodium atom because it has a different ground state electron configuration. In fact, any atom that differs from any other atom in ground state electron configuration is a different element.
Which element is predicted to have the ground-state electron configuration He 2s 2 2p 2?
The configuration [He] 2s2 2p2 describes the element in the 2nd row (since He finishes the first row) in the second of the 'p' columns, #14. This corresponds to the element carbon.

What is the ground state electron configuration of the element Lanthanum?
[Xe]6s24f1
Which element has a half-filled 3s orbital in the ground state?
sodium(Na)
What element has the outer electron configuration 6s2 4f8?
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 electron configuration Ar4s1 is the ground state electron configuration of?
The electron configuration of 1s22s22p3s1 is not the ground state electron configuration of any element. This configuration contains 8 electrons, which in the ground state would be oxygen. The ground state configuration of oxygen is 1s22s22p4.
