lesson 1
What is a valence electron
An electron in the outer most shell
The electrostatic force that holds oppositely charged particles together in an ionic compound
What is an ionic compound
Something gives a ratio of cation to anions in the ionic bonds.
What is the formula unit?
Force that holds two atoms together.
What is chemical bond?
What is a cation
Cations are a positively charged ion
An ionic compound whose aqueous solution conducts an electric current
What is an electrolyte
This is formed from one atom. The atomic ions is equal to its oxide numbers.
What is monotonic ions?
Metal is mixed with one or more other elements.
How is an alloy formed?
What is an anion
An anion is a negatively charged ion
The strong attractions among the positive ions and the negative ions in an ionic compound
What is a crystal lattice
The name for Mg(OH)2.
What is Magnesium Hydroxide?
The electron sea model explains the physical properties of metallic solids.
What is the metallic bond?
What is a chemical bond
A chemical bond is the force that holds two atoms together.
Compounds that contain ionic bonds
What is an ionic compound
Write the formula for Sodium Bromide.
What is NaBr?
Electrons move through the metallic crystal and are not held by any particular atom.
What is the delocalized electron?
When does a positive ion form
A positive ion forms when an atom loses one or more valence electrons in order to attain a noble gas configuration
The energy required to separate 1 mol of the ions of an ionic compound
What is lattice energy
Ion comes first in the name and formula of an ionic compound.
What is the cation (positive ion)?
A metallic bond forms when metal cations attract freely moving, delocalized valence electrons.
What is electron sea model?
