Question

1. drag and drop the words with the descriptions.

a bond where electrons are shared equally
a bond where one atom has a great strength of attraction for the shared
electrons
when two atoms of the same element are bonded covalently
when two atoms share electrons to create a bond
the attraction between oppositely charged ions
the attraction between two metal atoms
valence electrons that do not belong to any one atom

Explanation:

• For "a bond where electrons are shared equally", in non - polar covalent bonds, there is no significant difference in electronegativity between the atoms, so electrons are shared equally.
• For "a bond where one atom has a great strength of attraction for the shared electrons", in polar covalent bonds, there is a difference in electronegativity, and the more electronegative atom has a stronger attraction for the shared electrons.
• For "when two atoms of the same element are bonded covalently", diatomic molecules (e.g., \(H_2\), \(O_2\)) are formed when two atoms of the same element bond covalently.
• For "when two atoms share electrons to create a bond", this is the general definition of a covalent bond.
• For "the attraction between oppositely charged ions", this is the definition of an ionic bond.
• For "the attraction between two metal atoms", metallic bonds involve the attraction between metal cations and delocalized electrons, which can be thought of as the attraction between metal atoms in a metallic lattice.
• For "valence electrons that do not belong to any one atom", delocalized electrons are valence electrons that are not localized to a single atom in a metallic or some other extended structure.
