Question

${}_{17}{}^{}\mathrm{D}$ is the element in which subscript denotes the atomic number. Write the electronic configuration of the element.

Answer 1

Electronic configuration — the distribution of an electron in a given shell or orbital is known as electronic configuration.

• It is also called electronic structure.
• It also helps to predict whether the element is metal, non-metal, metalloids, or inert gas.
• It is followed by the number of electrons present in the orbital written in superscript.
• Electronic configuration of ${}_{17}{}^{}\mathrm{D}$ is 2,8,7.

Thus, the electronic configuration ${}_{17}{}^{}\mathrm{D}$ is 2,8,7.
