Question

define ionic bond
1 point
options:

• when two atoms share electrons equally
• when two atoms share electrons unequally
• when two ions of opposite charge are attracted to each other and sit next to each other
• when two molecules with partial charge are attracted to each other and set next to each other

Explanation:

To define an ionic bond, we recall that an ionic bond is formed by the electrostatic attraction between ions of opposite charges (a cation and an anion). Let's analyze each option:

• "When two atoms share electrons equally" describes a non - polar covalent bond.
• "When two atoms share electrons unequally" describes a polar covalent bond.
• "When two molecules with partial charge are attracted to each other" describes intermolecular forces (like dipole - dipole interactions), not an ionic bond.
• "When two ions of opposite charge are attracted to each other and sit next to each other" matches the definition of an ionic bond, as ionic bonds involve the attraction between positively and negatively charged ions.

Answer:

The option "When two ions of opposite charge are attracted to each other and sit next to each other" (the first option in the second column of the given choices).
