Monatomic Ions

Front

What is a monatomic ion?

Back

A monatomic ion is an ion consisting of a single atom with a positive or negative charge due to the loss or gain of one or more electrons.

Back

The charge of a cadmium ion is +2, represented as Cd^2+.

Front

What is the charge of an iodide ion?

Back

The charge of an iodide ion is -1, represented as I^-.

Front

What is the charge of a silver ion?

Back

The charge of a silver ion is +1, represented as Ag^+.

Front

What is the charge of a barium ion?

Back

The charge of a barium ion is +2, represented as Ba^2+.

Front

What is the charge of a fluoride ion?

Back

The charge of a fluoride ion is -1, represented as F^-.

Front

How do you determine the charge of a monatomic ion from its position in the periodic table?

Back

The charge of a monatomic ion can often be determined by its group number in the periodic table; for example, elements in Group 1 form +1 ions, while those in Group 17 form -1 ions.

Front

What is the significance of the oxidation state in relation to monatomic ions?

Back

The oxidation state indicates the degree of oxidation of an atom in a compound, which corresponds to the charge of the ion when it is monatomic.

Front

What is the difference between cations and anions?

Back

Cations are positively charged ions formed by the loss of electrons, while anions are negatively charged ions formed by the gain of electrons.

Front

Provide an example of a monatomic cation and its charge.

Back

An example of a monatomic cation is sodium (Na^+), which has a charge of +1.
