Binary Ionic Formulas

Front

What is a binary ionic formula?

Back

A binary ionic formula represents a compound formed from two different elements, typically a metal and a non-metal, where the metal donates electrons to the non-metal.

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons, leading to greater stability.

Front

What charge does a phosphorus ion typically have when it gains electrons?

Back

A phosphorus ion typically has a charge of -3 when it gains 3 electrons.

Front

Which group of elements is most likely to form negative ions?

Back

Elements from group 17 (halogens) are most likely to form negative ions.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the highest energy level of an atom that are involved in chemical bonding.

What charge does oxygen typically have when it becomes an ion?

Back

Oxygen typically has a charge of -2 when it becomes an ion.

Front

If an element has 3 valence electrons, what charge will its ion likely have?

Back

The ion will likely have a charge of +3.

What is an anion?

Back

An anion is a negatively charged ion that has gained one or more electrons.

Front

What is a cation?

Back

A cation is a positively charged ion that has lost one or more electrons.
