Answer to Question #301373 in General Chemistry for rylee

Question

Use the octet rule to predict the formula of the compound that would form between arsenic and iodine , if the molecule contains only one arsenic atom and only single bonds are formed.  Formula:

Answer 1

Ans=AsH₃

Explanation.

The electron configuration of Arsenic is -3d¹⁰4s²4p³

Using the octet rule,we need to give As three more electrons to be completed.This means an ion of Arsenic will look like As^-3.And if the molecule contains only single bonds, only three H⁺ will attach
