Beryllium and magnesium have high charge density and small atomic size, making it energetically more favorable for them to form covalent bonds with hydrogen atoms to create polymeric hydrides. The formation of ionic hydrides would require a stronger electron transfer, which is less favorable due to the large ionization energy of these metals.
What else can I help you with?
Why beryllium and magnesium form polymeric hydride?
Because the electronegativities values of Be and Mg are high in comparission of other elements of the group. These two metals form poler covalent bond with hydrogen and due to polarity the units of these hydrides are linked to gather in the form of chain by hydrogen bond. so thier hydrides are called polymeric hydrides.
What are the differences between Ionic Hydrides and Covalent hydrides?
Ionic hydrides are formed between metals and hydrogen, where hydrogen gains an electron to form the hydride ion. Covalent hydrides are formed between nonmetals and hydrogen, where they share electrons to form covalent bonds. Ionic hydrides are typically solid at room temperature, while covalent hydrides can be gases, liquids, or solids.
Is Mg(OH)2 ionic or covelent?
Mg(OH)2 is an ionic compound. Magnesium (Mg) is a metal that tends to lose electrons to form a cation (Mg^2+), while hydroxide (OH) is a polyatomic ion that tends to gain electrons to form an anion (OH^-). Therefore, Mg(OH)2 is composed of ionic bonds between the magnesium cation and the hydroxide anions.
What is more likely to form an ionic compound Mg and F N and S O and Cl or Na and Al?
Mg and F are more likely to form an ionic compound because magnesium tends to lose 2 electrons to achieve a stable octet, while fluorine tends to gain 1 electron. This difference in electronegativity leads to the formation of an ionic bond between Mg and F. The other pairs do not exhibit as significant of an electronegativity difference to form an ionic compound.
Is mgo ionic or covalent bonding?
Ionic. because a metal(Mg) + a non-metal (O).

What pairs of elements is most likely to form an ionic compound Mg and F or O and Cl?
Mg and F is most likely to form an ionic compound because magnesium (Mg) has a +2 charge and fluorine (F) has a -1 charge, leading to a strong attraction between the two. Oxygen (O) and chlorine (Cl) also form ionic compounds, but the attraction between Mg and F is stronger due to their larger difference in electronegativity.
Is MgF an ionic compound or a covalent compound?
MgF2 Magnesium, an alkaline earth metal of 2+ ionic charge and two fluorine, a nonmetal, atoms of 1- charge each form a ionic bond
What type of bond will form between Mg and S?
An ionic bond will form between Mg and S. Magnesium will donate its two electrons to sulfur, which will accept them to achieve a stable electron configuration. This will result in the formation of magnesium sulfide, a compound held together by ionic interactions.
Is Mg ionic or molecular?
ionic
Is MgBr2 a molecular or ionic compound?
MgBr2 is an ionic compound. Magnesium (Mg) is a metal and bromine (Br) is a non-metal, so they form an ionic bond by transferring electrons.
What is the ionic compound of Mg and S?
MgS Magnesium Sulfide is ionic [citation reqd] MgSO4 is definitely ionic
What kind of bond is Mg and Cl?
Ionic- the difference in electronegativity is high (Mg 1.31, Cl 3.16)
