Q. What kind of compound is Sil4?
Silicon Iodide
Q. Is H2O ionic or covalent?
Water is a Polar Covalent Molecule Water (H2O), like hydrogen fluoride (HF), is a polar covalent molecule.
Q. How do you know if a compound is ionically bonded or covalently bonded?
By definition, an ionic bond is between a metal and a nonmetal, and a covalent bond is between 2 nonmetals. So you usually just look at the periodic table and determine whether your compound is made of a metal/nonmetal or is just 2 nonmetals.

Q. What are the differences between ionic and covalent bonds?
Differences between ionic and covalent bonds In covalent bonds, atoms share electrons, whereas in ionic bonds atoms transfer electrons. The reaction components of covalent bonds are electrically neutral, whereas for ionic bonds they are both charged.
Q. Which is the common characteristic of a covalent compound?
Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds.
Q. What are three 3 examples of covalent compounds?
Examples of covalent compounds include:
- O2 – oxygen.
- Cl2 – chlorine.
- PCl3 – phosphorus trichloride.
- CH3CH2OH – ethanol.
- O3 – ozone.
- H2 – hydrogen.
- H2O – water.
- HCl – hydrogen chloride.
Q. Why do covalent compounds burn?
3) Covalent compounds tend to be more flammable than ionic compounds. The main reason that things burn is because they contain carbon and hydrogen atoms that can react to form carbon dioxide and water when heated with oxygen gas (that’s the definition of a combustion reaction).
Q. Are covalent compounds hard?
Covalent bonds are extremely strong, so covalent solids are very hard. Generally, covalent solids are insoluble due to the difficulty of solvating very large molecules.
Q. How can you experimentally determine whether a compound is ionic or covalent?
You cannot tell whether a compound is ionic or covalent simply by looking at a sample of it because both types of compounds can look similar. However, simple test can be done to classify compounds by type because each type has a set of characteristic properties shared by most members.
Q. Why do solid covalent compounds have low melting points?
Covalent compounds have weak forces of attraction between the binding molecules. Thus less energy is required to break the force of bonding. Therefore covalent compounds have low melting and boiling point.
Q. What is the relation between melting point and covalent character?
On one hand, covalent character increases the bond dissociation enthalpy (i.e., more energy is needed to be put in) and on the other it lowers the melting point of Al2O3 to a value lower then would be expected with perfect ionic bonding.
