This shows 19 electrons, with 4s1 as a valence electron. This is potassium (K).
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.
The element with that electron configuration is Iron.
[Xe]6s24f1
Minor quibbling about the format of the question aside, sulfur is the element with that ground state electronic configuration.
The atomic number of zinc is 30. Its abbreviated electron configuration is [Ar]4s23d10 The full electron configuration is 1s22s22p63s23p64s23d10 (configurations for the atom in its ground state. Ions and excited atoms have different configurations).
The electron configuration for a ground-state potassium atom is 1s22s22p63s23p64s1. The noble gas shorthand configuration is [Ar]4s1.
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.
The element with that electron configuration is Iron.
[Xe]6s24f1
It is the electron configuration of a neutral, not excited atom.
The symbol for sulfur is S. Its electron configuration is 1s22s22p63s23p4
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.
Minor quibbling about the format of the question aside, sulfur is the element with that ground state electronic configuration.
The element is argon
The atomic number of zinc is 30. Its abbreviated electron configuration is [Ar]4s23d10 The full electron configuration is 1s22s22p63s23p64s23d10 (configurations for the atom in its ground state. Ions and excited atoms have different configurations).
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.
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.
