Compare ionic, covalent, and hydrogen bonding, and fully describe an example of each.
Is this right and I need help with an example of a covalent bond.
Ionic bond is formed from one metal and one non metal. It is a solid at room temperate. In an ionic bond and electron is transferred to another atom. In the process of either losing or gaining negatively charged electrons, the reacting atoms create ions. The oppositely charged ions are attracted to each other by electrostatic forces which is the basis for the ionic bond.
Example-When an electron from sodium is transferred over to the chlorine atom it allows the sodium atom to be stable. as it doesn’t have any electrons in its valence shell, and the chlorine is stable as well, as it has a full valence shell.
Covalent bonding is formed with two non metals. It is a liquid or gaseous at room temperature. In the covalent bonding the atoms share the electron. If the electron is shared equally between the atoms forming a covalent bond, then the bond is said to be non polar.
If the electron is more attracted to one atom than to another, it forms a polar covalent
Hydrogen bonds exist between two polar molecules that contain hydrogen. When the partially positive end of one polar molecule is attracted to the partially negative end of another polar molecule you have a hydrogen bond.
Example-Water has partially positive and negative ends. Hydrogen atoms are partially positive, but the oxygen atoms are partially negative. When water molecules are close to each other, the partially positive hydrogen ends find themselves attracted to the partially negative oxygen ends creating a hydrogen bond.
