Ionic Compounds
This term describes a substance dissolved in water.
What is an aqueous solution?
In the electron sea model, the freely moving electrons are known by this term.
What are delocalized electrons?
These two properties describe a metal’s ability to be hammered into sheets or drawn into wires.
What are malleability and ductility?
These are specific locations where a crystal can begin forming.
What are nucleation sites?
A compound that carries an electric current when dissolved in water is called this.
What is an electrolyte?
Ionic compounds form this type of repeating 3‑D structure that balances attractive and repulsive forces.
What is a crystal lattice?
Metals conduct electricity because these charged particles can move freely through the lattice.
What are electrons?
Metals typically have high boiling points because atoms must escape this structure.
What is the metallic lattice?
A high concentration of ions tends to produce many crystals, while a low concentration produces fewer but ______ ones.
What are larger?
Solid ionic compounds cannot conduct electricity because their ions are in this type of position.
What is fixed or rigid?
(This isn't on the test.)
These ions combine in ratios based on the number of electrons transferred from metals to nonmetals.
What are positive and negative ions?
This model describes metals as positive ions surrounded by a sea of mobile valence electrons.
What is the electron sea model?
What is the chemical formula of potassium carbide?
What is K4C? or K4C1?
Crystal lattices made of small, tightly packed ions have ______ lattice energy.
What is high?
When dissolving salt (sodium chloride) in water, the water carries an electrical current because of this.
What is sodium? or the metal?
The energy required to break one mole of bonds in an ionic crystal lattice is called this.
What is crystal lattice energy?
Metals are malleable because layers of atoms can do this without breaking the structure.
What is slide past each other?
A metal’s hardness comes partly from the ability of the electron sea to distribute this.
What is applied force or stress? (or hitting it??)
This is a unit of measurement, used for counting the number of atoms or molecules. It is equal to 6.02x10^23.
What is a mole?
When magnesium reacts with oxygen it is called this.
What is magnesium oxide?
According to naming rules, the ionic compounds ends in this suffix.
What is -ide?
Despite metals not being ionic as solids, they become ionic when they interact with this type of element.
What is a nonmetal?
These electrons move thermal energy from one part of a metal to another, making metals good heat conductors.
What are mobile valence electrons? or delocalized electrons? or the valence electrons that left the atom and became part of the Sea of Electrons?
Larger ions pack less tightly in a lattice, resulting in this change to the lattice energy.
What is it decreases?
When Calcium reacts with the polyatomic ion nitrite it is called this.
What is calcium nitrite?
