Common Monatomic Ions

The chemical symbol H+ represents a hydrogen ion with a positive charge, also known as a proton. He+ is the symbol for helium with a positive charge. O- represents oxygen with a negative charge. Na+ is the symbol for sodium with a positive charge.

The correct chemical symbol for a lithium ion is Li+ because it has a positive charge of +1, indicated by the plus sign.

The correct chemical symbol for sodium is Na, derived from its Latin name 'natrium'.

The correct chemical symbol for potassium is K, representing its Latin name 'kalium'.

The correct chemical symbol for Cs+ is cesium (1+), which indicates that cesium has a positive 1 charge. The other options do not match the correct chemical symbol for Cs+.

In the compound Ag+, the oxidation state of silver is +1. This is because silver typically exhibits a +1 oxidation state in its compounds.

The chemical symbol for magnesium ion with a +2 charge is Mg 2+. It is important to differentiate magnesium from other elements like manganese, mercury, and molybdenum which have similar symbols but different properties.

The correct symbol for Calcium with a +2 charge is Ca 2+. It indicates that calcium has lost two electrons and therefore carries a positive charge.

The correct answer is 'Sr2+' which represents Strontium with a +2 charge. The incorrect answers do not specify the charge, symbol or both elements correctly.

Barium ion with a +2 charge is written as Ba 2+ to indicate the element Ba (Barium) with a +2 charge.

Zinc forms a 2+ cation by losing two electrons in order to achieve a stable electronic configuration.

Cd 2+ represents the ion of Cadmium with a charge of +2. It is important to note the specific element being referred to in the question in order to provide the correct answer.

Aluminum forms a 3+ ion by losing 3 electrons, resulting in a charge of +3.

The correct chemical symbol for the hydride anion is H-, indicating that it is a negatively charged ion with a -1 charge.

Fluoride ion has a charge of -1 because it gains one electron to achieve a stable electronic configuration.

The correct chemical symbol for Chloride is Cl-. The minus sign denotes the chloride ion having a negative charge.

Bromine is represented by the chemical symbol Br, not B, Bo, or Bi. It is a halogen element with atomic number 35.

The correct symbol for Iodide -1 is I-, where the negative sign indicates the -1 charge on the ion. The other options provided are incorrect as they do not represent the correct charge or composition of the iodide ion.

O 2- is an anion as indicated by the negative charge associated with the oxygen atom.

The correct chemical symbol for sulfide with a charge of -2 is S2-. The symbol represents a sulfide ion with a charge of -2, formed when sulfur gains two extra electrons.

The nitride ion has a charge of -3, making it an anion. An anion is an ion that has gained one or more electrons, resulting in a negative charge.
