NGSS.HS-PS1-3

Identify the types of bonds

• ionic bond

• The force that holds two atoms together; may form by the

  attraction of a positive ion for a negative ion or by sharing

  electrons

• metallic bond

• The attraction of a monatomic cation for delocalized

  electrons

• chemical bond

• The electrostatic force that holds oppositely charged

  particles together in an ionic compound

• is a non-conductive material

• is always a solid

NGSS.HS-PS2-5

A three-dimensional geometric arrangement of particles in which each positive ion is surrounded by negative ions and each negative ion is surrounded by positive ions; vary in shape due to sizes and relative numbers of the ions bonded.

• lattice energy

• crystal lattice
• formula unit

NGSS.HS-PS1-3

The energy required to separate one mole of the ions of an ionic compound, which is directly related to the size of the ions bonded and is also affected by the charge of the ions.

• lattice energy
• crystal lattice

• formula unit

NGSS.HS-PS2-4

The simplest ratio of ions represented in an ionic compound.

• lattice energy

• crystal lattice

• formula unit

A(n) ​ (a)   is an ion made up of a single atom with a positive or

negative charge, while a(n)​ (b)   is a group of atoms bonded

together that acts as a single unit with a net charge.

• monatomic ion
• polyatomic ion

An oxyanion is a polyatomic ion that contains:

• Oxygen and hydrogen atoms

• Only oxygen atoms

• Oxygen and one or more other elements

• Only hydrogen atoms

What are TWO names for the model that proposes that all metal atoms in a metallic solid contribute their valence electrons to flow between the metal cations, and can explain properties of metallic solids such as malleability, conduction, and ductility?

• Ionic Bonding Model

• Covalent Bonding Model

• Metallic Bonding Model

• Van der Waals Model
