unit 5 ionic materials

What are the key properties of ionic compounds regarding their appearance and structure?

Ionic compounds have a crystalline appearance with geometric shapes and lattice corners.

How do ionic compounds conduct electricity?

Ionic compounds do not conduct electricity as solids, but they do conduct electricity in solution.

What is the state of elemental composition in ionic compounds?

Ionic compounds are composed of metals and nonmetals.

What is meant by 'formula units' in the context of ionic compounds?

A formula unit is the smallest repeating unit in an ionic compound's crystal structure.

How do you determine the charge of an element using the staircase method?

The charge can be determined by looking at the element's column and whether it is easier for the element to lose or gain electrons.

What defines a compound in chemistry?

A compound specifically refers to ionic bonds made up of a metal and a nonmetal.

What is electrostatic attraction in ionic compounds?

Electrostatic attraction is the force that holds together positively charged cations and negatively charged anions.

What happens to the overall charge of an ionic compound when it is formed?

The overall charge of an ionic compound is neutral, meaning there is an equal number of positive and negative charges.

What occurs when electrons are transferred from metal to nonmetal in ionic bonds?

When electrons are transferred, the metal becomes a cation and the nonmetal becomes an anion.

What is required for an atom to achieve a stable electron configuration in ionic bonding?

A full valence shell is required for stable electron configuration, leading to the formation of ionic bonds.
