Question

Based on the following electron configuration, [Kr]5s24d105p5, this element would most likely _____.

loss an electron to form a -1 anion and could form an ionic bond with a metal
gain an electron to form a -1 anion and could form an ionic bond with a metal
gain an electron to form a -1 anion and could form an ionic bond with a non-metal

Answer 1

Answer:Iodine (I)

Explanation: As it is predictable that element of which configuration is given can only accept electron to achieve stability. This nature is mostly shown by halogen elements.

Before Kr, Br is halogen and required halogen is after Kr which will be Iodine.
