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.
Why is BiH3 the strongest reducing agent amongest the hydrides of group 15 elements?
BiH3 is the strongest reducing agent among the hydrides of group 15 elements because of its high bond dissociation energy. This makes it easier for BiH3 to donate electrons and reduce other compounds. Additionally, bismuth has a lower electronegativity compared to the other group 15 elements, making it more willing to donate electrons in chemical reactions.
What covalent bonds are most polar?
Bonds between two nonmetals that differ in electronegativity (EN) are usually polar. Electronegativity is the tendency of an atom to attract electrons. Nonmetals with EN differences of 0.5-1.6 form polar covalent bonds. The greater the difference, the more polar. If the EN difference is
What are some household items that contain non-polar covalent bonds?
Some household items that contain non-polar covalent bonds are cooking oil, plastic containers, and gasoline. These substances consist of molecules with similar electronegativities, leading to shared electron pairs and non-polar covalent bonds.
Which of these pairs of elements would most likely form non-polar covalent bonds Al and Br or Zn and Br or Br and Br or H and H?
Both Br and Br and H and H form non-polar covalent bonds.
What are the differences between Ionic Hydrides and Covalent hydrides?

Ionic hydrides are typically solid at room temperature, while covalent hydrides can be gases, liquids, or solids.
What type of elements does polar bonds apply to?
polar bonds arise from differences in electronegatvity between the atoms involved. The elemnts most likely to have polar bonds are those with high electronegativity.
What metals can bond with hydrogen?
Metals such as iron, nickel, platinum, and palladium can form bonds with hydrogen to create metal hydrides. These metal hydrides are often used in various industrial processes, including hydrogen storage and purification.
Is the bond between nitrogen and hydrogen polar or non-polar?
Oxygen is an element, not a bond. It will form polar bonds with most other elements, though because it is very electronegative. However, when it bonds with itself as in O2 the bonds are nonpolar.

How do you classify hydrides?
There are three types of hydride: saline, metallic and covalent (there are alternative names for the types of hydride, but these are most common). Saline hydrides have crystalline, salt like structures, and are formed with hydrogen and the group 1 and group 2 metals (the alkali metals and the alkaline earth metals). Metallic hydrides are brittle solids with fairly simple structures, generally formed between hydrogen and the transition metals. They can often have non-integer stoichiometries, e.g. ZrH1.3. Covalent hydrides are formed between hydrogen and the p-block elements, and tend to be gases as room temperature (there are exceptions to this, because of hydrogen bonding).
Which has bonds that are most polar SCl2 F2 CS2 CF4 BrCl?
The most polar bonds would be found in SCl2 and BrCl since S and Br are more electronegative than the other atoms in the molecules (Cl). This difference in electronegativity leads to unequal sharing of electrons, creating more polar bonds.
Why alkali metals form ionic hydrides?
SHORT ANSWER: the difference in electronegativities between H and Alkali metals is high, so the bonds are more ionic.
Carbohydrates and lipids are very large organic molecules Which two bonds do you expect to find most in these molecules?
ANSWER: nonpolar cavalent bonds and polar covalent bonds
What are some household items that contain non-polar covalent bonds?
Some household items that contain non-polar covalent bonds are cooking oil, plastic containers, and gasoline. These substances consist of molecules with similar electronegativities, leading to shared electron pairs and non-polar covalent bonds.
Which of these pairs of elements would most likely form non-polar covalent bonds Al and Br or Zn and Br or Br and Br or H and H?
Both Br and Br and H and H form non-polar covalent bonds.
