E. Halogens
F. Noble Gases
This was answered below with a question from Londy. About half the page down.
To determine the answer to this question, we need to consider the properties of ionic hydrides and the elements in different groups of the periodic table.
Ionic hydrides are compounds composed of a metal cation and a hydride anion (H-). They are formed when a metal reacts with hydrogen.
In the periodic table, Group 1A elements are the alkali metals such as lithium (Li), sodium (Na), and potassium (K). Group 2A elements are the alkaline earth metals including beryllium (Be), magnesium (Mg), and calcium (Ca).
Transition metals are located in the d-block of the periodic table and include elements such as iron (Fe), copper (Cu), and zinc (Zn).
Nonmetals are found to the right of the periodic table and include elements like carbon (C), nitrogen (N), and oxygen (O).
Halogens are specifically found in Group 7A and include elements like fluorine (F), chlorine (Cl), and iodine (I).
Noble gases are located in Group 8A and include elements such as helium (He), neon (Ne), and argon (Ar).
Ionic hydrides of the type MH2 are most likely to form between hydride and elements of Group 2A (alkaline earth metals). Therefore, the correct answer to the question is B: Group 2A.
