Final answer:

The elements with the abbreviated electron configurations [Ne], [Ar], and [Xe] are the noble gases Neon, Argon, and Xenon respectively, which occupy the 10th, 18th, and 54th positions on the periodic table.

Step-by-step explanation:

To identify the elements with the given abbreviated electron configurations, we shall refer to the periodic table and the principles of electron configurations:

  • For [Ne], this is the electron configuration for the element Neon itself, which has a full 2s and 2p subshells, making its electron configuration 1s² 2s² 2p¶. Neon is the 10th element on the periodic table.
  • For [Ar], Argon is the noble gas in question, with an electron configuration that ends with a full 3s and 3p subshell. It is represented as 1s² 2s² 2p¶ 3s² 3p¶. Argon is the 18th element on the periodic table.
  • For [Xe], Xenon is the noble gas with a filled 5p subshell, represented as 1s² 2s² 2p¶ 3s² 3p¶ 3dⁱ⁰ 4s² 4p¶ 4dⁱ⁰ 5s² 5p¶. Xenon is the 54th element on the periodic table.
