Many elements combine with hydrogen(valence = 1) to give compounds called hydrides.
Use the position of an element in the periodic table to deduce its valence.
Write formulas for these hydrides without using subscripts, for example XH3.
If no hydride forms, write "none".

What is the formula of the hydride formed by helium?

What is the formula of the hydride formed by xenon?

Answer #1

What is the formula of the hydride formed by helium answer : NONE

What is the formula of the hydride formed by xenon? answer : NONE

explanation:

in the periodic table . He , Ne, Ar , Kr , Xe , Rn . these elements are called inert gases or zero group elements . so these elements cannot form any compounds except with higher electronegative elements like F and O

suppose Xe for XeF2, XeF4,XeF6 , XeO3, XeO4 . other compouds are not possible.

due to inertness of He and Xe . the outermost shell is completely filled

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...
