Ionic compounds quiz naming formula writing and naming

Naming ionic compounds quiz

If the compounds are positively charged they are known as cations. Start by writing the metal ion with its charge, followed by the nonmetal ion with its charge. For example, lithium hydrogen phosphate contains three elements: lithium, which is a cation, and hydrogen phosphate. One charged atom is called a monoatomic ion, while a binary covalent compound is composed of two non-metal atoms. Write the correct formula for an ionic compound. In the solid state, ionic compounds are in crystal lattice containing many ions each of the cation and anion. Ionic compounds are composed of ions. Then give the Greek prefix for the number of the second atom. For instance, Mg3N2 refers to magnesium nitride, because magnesium is the cation, and nitrogen can be deduced as forming an anion of charge equal to the group number minus 8, which is N3-, the nitride ion. Ionic compounds do not exist as molecules.

In the solid state, ionic compounds are in crystal lattice containing many ions each of the cation and anion. Because the molecule is an ion, it means it has an overall electrical charge. The naming convention follows a specific formula.

naming covalent compounds practice

Signs of the charges are dropped. This formula merely indicates that sodium chloride is made of an equal number of sodium and chloride ions. The -ate form: for example, sulfate, SO The -ite form has one less oxygen that the -ate form: sulfite, SO These suffixes -ate and -ite denote the relative number of oxygen atoms in the oxoanion.

The prefix thio- in a compound means that an oxygen atom has been replaced by a sulfur atom.

Reduce to the lowest ratio. The tetra- prefix on the fluoride stem name indicates that there are 4 fluoride atoms in this compound. One charged atom is called a monoatomic ion, while a binary covalent compound is composed of two non-metal atoms.

The cation is named first, then the second part of the name is the anion and its known or deduced charge.

Naming compounds practice problems with answers

Write the symbol and charge of the cation metal first and the anion nonmetal second. Because the molecule is an ion, it means it has an overall electrical charge. The first step is to identify the elemental cation and anion, and then name them. Then name the second atom and end it with -ide. Generally, the first atom when read left to right is the least abundant in the compound. Solution Write the formula for aluminum nitride Write the formula for lithium oxide 1. As you would in the other cases, specify the formula, charge and number of each ion. First, give the name of the first atom in the compound. Her work has appeared in the global print magazine Overture, which examines the intersection of science and technology for the betterment of humanity. Leave out all charges and all subscripts that are 1. This formula indicates that this compound is made up of twice as many sodium ions as sulfide ions. She provides articles for print publications across her region, as well as online publications such as College Choice. Start by writing the metal ion with its charge, followed by the nonmetal ion with its charge. If the compounds are positively charged they are known as cations.

For example, lithium hydrogen phosphate contains three elements: lithium, which is a cation, and hydrogen phosphate.
