Naming Binary Ionic compounds

Front

What is a binary ionic compound?

Back

A binary ionic compound is a chemical compound composed of two different elements, one being a metal and the other a non-metal, that are held together by ionic bonds.

How do you determine the formula of a binary ionic compound?

Back

To determine the formula, identify the charges of the ions, then combine them in a ratio that results in a neutral compound.

What is the formula for sodium oxide?

Back

The formula for sodium oxide is Na2O.

Front

What is the significance of valence electrons in ionic bonding?

Back

Valence electrons are the outermost electrons of an atom and are involved in forming bonds; metals lose them to form positive ions, while non-metals gain them to form negative ions.

Front

What type of bond is formed between metals and non-metals?

Back

Ionic bonds are formed between metals and non-metals.

Front

What is the dot diagram used for?

Back

A dot diagram represents the valence electrons of an atom, helping to visualize how atoms bond.

What is the charge on the iron ion in Fe2O3?

Back

The charge on the iron ion in Fe2O3 is +3.

Front

What does the subscript in a chemical formula indicate?

Back

The subscript indicates the number of atoms of the element in the compound.
