What are 10 examples of covalent?
Examples of Covalent Bonds
- Hydrogen (H2) Hydrogen (H) is the simplest of all elements.
- Oxygen (O2) The valency of oxygen (O) is two, which means that it requires two electrons to complete its outermost (valence) shell.
- Nitrogen (N2)
- Water (H2O)
- Carbon Dioxide (CO2)
- Methane (CH4)
- Ammonia (NH3)
- Carbon Monoxide (CO)
What is the formula for a covalent compound?
Each covalent compound is represented by a molecular formula, which gives the atomic symbol for each component element, in a prescribed order, accompanied by a subscript indicating the number of atoms of that element in the molecule. The subscript is written only if the number of atoms is greater than 1.
What are the names of covalent compounds?
Binary molecular (covalent) compounds
| compound | systematic name |
|---|---|
| NO2 | nitrogen dioxide |
| N2O3 | dinitrogen trioxide |
| N2O4 | dinitrogen tetroxide |
| N2O5 | dinitrogen pentoxide |
What are the names and formulas of compounds?
Chemical Compound Formulas
| Compound name | Molecular formula | |

What are 5 Covalent compounds?
Examples of Covalent Compounds
- O2 – oxygen.
- Cl2 – chlorine.
- PCl3 – phosphorus trichloride.
- CH3CH2OH – ethanol.
- O3 – ozone.
- H2 – hydrogen.
- H2O – water.
- HCl – hydrogen chloride.
Is NaCl covalent?
As we have seen, there are two types of bonds: ionic bonds and covalent bonds. For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals.
Is mg no3 2 ionic or covalent?
Magnesium Nitrate is an ionic compound formed by cation Magnesium Mg2+, and polyatomic anion Nitrate NO3–. The charges must be equal and the opposite in order for these two ions to bind.
What are the names of these covalent compounds?
CCl 4,the covalent molecule that is formed when carbon and chlorine bond with one another.
What are the rules on naming covalent compound?
Certain rules apply to the way names of covalent compounds are written: The more electropositive element (further left on the periodic table) is listed before the more electronegative element (further right on the periodic table). The second element is given an -ide ending. Prefixes are used to denote how many atoms of each element are present in the compound.
What are examples of covalent bonds?
Some examples of covalent bonds are methane (CH 4), hydrochloric acid (HCL), water (H 2O) and ammonia (NH3). Hydrochloric acid pulls the electron pair toward the chlorine atom , which has a higher electronegativity to form a covalent bond.
What are covalent compounds usually composed of?
Covalent compounds are generally made up of non-metals, or metal in a rare case. Elements such as oxygen and chlorine, for instance, which are both metals and non-metals.
