Question

Give the symbol for the atom that corresponds to each electron configuration. (add the electrons and then find on periodic table) A) 1s 22s 2 2p 6B) 1s 22s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 6 4d 7 5s 1C) 1s 22s 2 2p 63s 23p 6 3d 10 4s 2 4p 6 4d 10 4f 7 5s 2 5p 6 5d 1 6s 2

Answer 1

A) Nitrogen (N) B) Rhodium (Rh) C) Gadolinium (Gd)

A) The electron configuration 1s² 2s² 2p⁶ corresponds to nitrogen (N). This indicates that nitrogen has two electrons in its 1s orbital, five electrons in its 2s and 2p orbitals combined, adding up to a total of seven electrons.

B) The electron configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d⁷ 5s¹ corresponds to rhodium (Rh). Rhodium has 45 electrons distributed across its various orbitals as per the given configuration.

C) The electron configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 4f⁷ 5s² 5p⁶ 5d¹ 6s² corresponds to gadolinium (Gd). Gadolinium has a total of 64 electrons with the specified distribution among its electron shells and subshells.

These assignments are based on the principle that each element has a unique electron configuration, allowing us to identify the corresponding element on the periodic table. The periodic table organizes elements based on their atomic number and electron configuration, making it a valuable tool for understanding the properties and relationships among different elements.
