Electron Configuration and Position in the Periodic Table

The given electron configuration is 1s22s22p3 3s²3p'3d¹04s²4p¹. Let's break it down to identify the element and its position in the periodic table.

The electron configuration represents the distribution of electrons in an atom's energy levels or orbitals. Each number and letter in the electron configuration represents a specific orbital and the number of electrons it contains.

In the given electron configuration, we can identify the following orbitals and their electron counts:

- 1s²: This represents the 1s orbital, which can hold a maximum of 2 electrons. It is fully filled in this case. - 2s²: This represents the 2s orbital, which can also hold a maximum of 2 electrons. It is fully filled in this case. - 2p³: This represents the 2p orbital, which can hold a maximum of 6 electrons. It contains 3 electrons. - 3s²: This represents the 3s orbital, which can also hold a maximum of 2 electrons. It is fully filled in this case. - 3p': This represents the 3p orbital, which can hold a maximum of 6 electrons. The prime symbol (') indicates that it is partially filled. It contains 1 electron. - 3d¹: This represents the 3d orbital, which can hold a maximum of 10 electrons. It contains 1 electron. - 4s²: This represents the 4s orbital, which can also hold a maximum of 2 electrons. It is fully filled in this case. - 4p¹: This represents the 4p orbital, which can hold a maximum of 6 electrons. It contains 1 electron.

Based on this electron configuration, we can determine the element and its position in the periodic table. The element with this
