Classify each of the following as ionic or covalent. I did all but I am not really sure about this one. NH4NO3 I put covalent. Is this correct? Thanks
The main difference between ionic and covalent bonds is the way in which the atoms are held together. In an ionic bond, one atom donates an electron to another atom, resulting in a strong electrostatic attraction between the oppositely charged ions. In a covalent bond, atoms share electrons in order to achieve a full outer shell, resulting in a strong bond between the atoms.
To determine if a compound is ionic or covalent, you can look at the electronegativity difference between the atoms. If the electronegativity difference is greater than 1.7, the bond is considered ionic. If the difference is less than 1.7, the bond is considered covalent.
Ionic compounds tend to have high melting and boiling points due to the strong electrostatic attraction between the ions. They are also often soluble in water and form crystal structures. Additionally, ionic compounds are good conductors of electricity when dissolved in water or in a molten state.
Covalent compounds tend to have lower melting and boiling points compared to ionic compounds due to the weaker intermolecular forces between molecules. They are also often insoluble in water and do not form crystal structures. Covalent compounds are generally poor conductors of electricity.
Yes, a compound can have both ionic and covalent bonds. This type of bond is known as a polar covalent bond, where there is a partial transfer of electron density from one atom to another, resulting in a slight positive and negative charge on the atoms involved in the bond.
