Question

an asymmetry in the position of shared electrons in a bond, due to differences in the electronegativities of the atoms involved, that creates a partial positive charge on one atom and a partial negative charge on the second atom. an attraction between a partial positive charge on a hydrogen atom and a partial negative charge on another atom. the tendency for an atoms nucleus to attract the shared electrons in a covalent bond. the fundamental unit of an element, made of protons, neutrons, and electrons. an atom or molecule that carries a full charge - positive if it contains more protons than electrons, and negative if it contains more electrons than protons. a distinct type of substance or matter. each has atoms that contain a unique number of protons in the nucleus. an attraction between two atoms based on shared electrons. a structure made of two or more atoms held together by covalent bonds. molecule covalent bond element ion polar covalent bond hydrogen bond

Explanation:

• The first description matches the definition of a polar covalent bond.
• The second description is the definition of a hydrogen bond.
• The third description is about electronegativity.
• The fourth description is of an atom.
• The fifth description is of an ion.
• The sixth description is of an element.
• The seventh description is of a covalent bond.

Answer:

1. Polar covalent bond
2. Hydrogen bond
3. Electronegativity
4. Atom
5. Ion
6. Element
7. Covalent bond
