Question

each atom of an element has the following electron configuration. 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁵. what is the name of the element? bromine iodine tellurium xenon

Explanation:

Step1: Count total electrons

The superscripts in the electron - configuration represent the number of electrons in each orbital. Add them up: \(2 + 2+6 + 2+6 + 2+10 + 6+2 + 10+5=53\).

Step2: Identify element

The atomic number of an element is equal to the number of electrons in a neutral atom. The element with atomic number 53 is iodine.

Answer:

iodine
