Final answer:
The element with the electron configuration 1s²2s²2p⁶3s²3p⁶4s²3d² is titanium (Ti), which is found in the 4th period and is part of the d-block of the periodic table.
Step-by-step explanation:
The element with an electron configuration of 1s²2s²2p⁶3s²3p⁶4s²3d² is titanium (Ti). The electron configuration indicates the number of electrons in each shell and subshell. Starting with the 1s subshell, it's completely filled with 2 electrons, followed by the 2s subshell that is also filled with 2 electrons. The 2p subshell is also full with 6 electrons. This pattern continues with the 3s and 3p subshells being filled with 2 and 6 electrons, respectively. The final electrons enter the 4s subshell (with 2 electrons) before the 3d subshell, which contains 2 electrons, indicating that we are looking at an element in the d-block, specifically in the 4th period of the periodic table. As we follow the order of elements, this configuration matches that of titanium.
