The correct statement comparing ionic and covalent bonds is: Covalent bonds tend to be less polar than ionic bonds.

Here's a brief explanation for each of the options:

  1. The difference between electronegativities is greater for atoms in covalent bonds than for atoms in ionic bonds - This is incorrect because ionic bonds typically form between atoms with a large difference in electronegativity (usually greater than 1.7), while covalent bonds form between atoms with similar electronegativities.

  2. Covalent bonds tend to be less polar than ionic bonds - This is correct. Ionic bonds involve a complete transfer of electrons from one atom to another, resulting in charged ions, while covalent bonds share electrons and can vary in polarity depending on the electronegativity difference between the atoms.

  3. More electrons are transferred to form covalent bonds than ionic bonds - This is incorrect. In ionic bonds, electrons are transferred completely from one atom to another, while covalent bonds involve the sharing of electrons, not transferring multiple electrons.

  4. Elements in Group IA are more likely to form covalent bonds than ionic bonds with other atoms - This is incorrect. Group IA elements (alkali metals) typically form ionic bonds because they readily lose one electron to achieve a stable electron configuration.
