give a definition of ionic bonding
Can you not find this in your text or in your notes? An ionic bond is formed when electrons are transferred from one atom to another making the atom that lost electrons positively charged and the atom that gained electrons negatively charged.
i just wanted another opinion
Ionic bonding is a type of chemical bonding that occurs between atoms with significantly different electronegativities. It involves the complete transfer of one or more electrons from one atom, known as the donor or cation, to another atom, known as the acceptor or anion. This transfer of electrons results in the formation of positively charged cations and negatively charged anions that are held together by electrostatic forces of attraction.
To understand how ionic bonding works, it is important to have a basic understanding of electronegativity. Electronegativity is a measure of an atom's ability to attract electrons towards itself in a chemical bond. In an ionic bond, one atom has a much higher electronegativity than the other, causing it to attract and eventually take electrons from the other atom.
To determine whether a bond is ionic, you can look up the electronegativity values of the atoms involved. The most commonly used scale is the Pauling electronegativity scale. By comparing the electronegativity difference between two elements, you can classify the bond as either ionic, covalent, or polar covalent.
Generally, if the electronegativity difference is greater than 1.7, the bond is considered ionic. If the difference is between 0.5 and 1.7, the bond is polar covalent, meaning the electrons are shared unequally between the atoms. If the difference is less than 0.5, the bond is considered covalent, where electrons are shared equally.
In summary, ionic bonding is the strong electrostatic attraction between oppositely charged ions formed when electrons are transferred from one atom to another with significantly different electronegativities. The difference in electronegativity can be used to determine if a bond is ionic or not.
