This shows 19 electrons, with 4s1 as a valence electron. This is potassium (K).
The element with that electron configuration is Iron.
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 ground state electron configuration of Lanthanum is [Xe] 5d1 6s2.
The ground state electron configuration for the element with the atomic number corresponding to the keyword "fe" is Ar 3d6 4s2.
Minor quibbling about the format of the question aside, sulfur is the element with that ground state electronic configuration.
The electron configuration for a ground-state potassium atom is 1s22s22p63s23p64s1. The noble gas shorthand configuration is [Ar]4s1.
The element with that electron configuration is Iron.
The ground state electronic configuration of an element X can be determined by using the periodic table. Each element has a unique arrangement of electrons in its atoms. For example, the ground state electronic configuration of carbon (C) is 1s2 2s2 2p2.
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 ground state electron configuration of Lanthanum is [Xe] 5d1 6s2.
The ground state electron configuration for the element with the atomic number corresponding to the keyword "fe" is Ar 3d6 4s2.
Minor quibbling about the format of the question aside, sulfur is the element with that ground state electronic configuration.
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 is argon
The symbol for sulfur is S. Its electron configuration is 1s22s22p63s23p4
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 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.
