On each blank, write the chemical symbol for the ion

1. a sulfur ion with a charge of -2=

2. an iron ion with a charge of +3

3. a chlorine ion with a charge of -3

answer today its homework do

A sulfur ion with a charge of -2 = S⁻²

An iron ion with a charge of +3 = Fe⁺³

A chlorine ion with a charge of -3 = Cl⁻³

Explanation:

Anion:

Anion are formed when an atom  gain the electrons.

Representation:

The anion of an atom is showed by adding the number of electrons gained by atom with negative sign as superscript on the symbol of an atom.

Cation:

Cation is formed when an atom lose the electron.

Representation:

The cation of an atom is showed by adding the number of electrons lose by an atom with positive sign as superscript on the symbol of an atom.

A sulfur ion with a charge of -2 = S⁻²

An iron ion with a charge of +3 = Fe⁺³

A chlorine ion with a charge of -3 = Cl⁻³

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
