A chemical compound formed from gallium cation (Ga³⁺) and phosphide anion (P³⁻).

NaCl

MgO

AlN

CaH2

Calcium chloride is formed when Calcium ions (Ca²⁺) and Chloride ions (Cl⁻) combine in a chemical reaction.

Potassium phosphate is formed when potassium ions (K⁺) combine with phosphate ions (PO₄)³⁻ , according to their valencies.

Calcium Carbonate is formed when Calcium ions (Ca²⁺) and Carbonate ions (CO₃)²⁻ combine to form a solid.

Ammonium hydroxide is formed when Ammonium ions (NH₄⁺) and Hydroxide ions (OH⁻) combine.

Strontium Bromide is formed when Strontium ions (Sr²⁺) and Bromide ions (Br⁻) combine.

A cation is a positively charged ion that is formed when an atom loses electrons.

An anion is a negatively charged ion that is formed when an atom gains electrons.

1. Name the first element (cation). 2. Write the root name of the second element (anion). 3. Change the ending of the anion name to -ide.

AlBr₃

Na₂SO₄

The formula for Antimony Tribromide is SbBr3. It consists of one antimony (Sb) atom and three bromine (Br) atoms.

The formula for Chlorine Dioxide is ClO2. It consists of one chlorine (Cl) atom and two oxygen (O) atoms.

The formula for Hydrogen Iodide is HI. It contains one hydrogen (H) atom and one iodine (I) atom.

Iodine Pentafluoride has the formula IF5. It consists of one iodine (I) atom and five fluorine (F) atoms.

The formula for Dinitrogen Trioxide is N2O3. It contains two nitrogen (N) atoms and three oxygen (O) atoms.

A system for naming compounds composed of nonmetals, using prefixes to indicate the number of atoms of each element.

Prefixes are used to indicate the number of atoms of each element in a covalent compound.

When a covalent compound contains one atom of each element, the prefix 'mono' is often omitted from the first element's name.

The suffix '-ide' is added to the root of the second element's name in covalent compounds.

1. Name the first element. 2. Add a prefix to the first element if there are more than one atom of it. 3. Name the second element and add the suffix '-ide'. 4. Use prefixes to show the number of atoms of the second element.

The formula for Zinc Nitrate is Zn(NO₃)₂. Zinc has a combining power of 2, and nitrate has a combining power of 1, so two nitrate ions are needed to balance the charge.

The formula for Ammonium Phosphate is (NH₄)₃PO₄. Ammonium has a combining power of 1, and phosphate has a combining power of 3, so three ammonium ions are needed to balance the charge.

Brackets are used in chemical formulas to enclose polyatomic ions (groups of atoms that act as one unit) when there is more than one of them in the compound. This ensures clarity and avoids confusion about how many of each ion are present.

The formula for Silver Sulfate is Ag₂SO₄. Silver has a combining power of 1, and sulfate has a combining power of 2, so two silver ions are needed to balance the charge.

The formula for Aluminum Carbonate is Al₂(CO₃)₃. Aluminum has a combining power of 3, and carbonate has a combining power of 2, so two aluminum ions and three carbonate ions are needed to balance the charge.
