Introduction

Chemistry is a fascinating field that deals with the study of the composition, properties, and reactions of matter. In this article, we will focus on the chemical formulas and names of compounds, specifically the compounds formed by the reaction of metals with nonmetals. We will complete the table below by writing the formulas and names of compounds.

Compounds Formed by Reaction with Chloride Ion

The chloride ion (Cl-) is a common anion that is formed by the reaction of metals with chlorine gas. When a metal reacts with chlorine gas, it loses one or more electrons to form a cation, and the chlorine gas gains one or more electrons to form a chloride ion. The resulting compound is a salt that consists of the metal cation and the chloride ion.

For example, when sodium (Na) reacts with chlorine gas, it loses one electron to form a sodium cation (Na+), and the chlorine gas gains one electron to form a chloride ion (Cl-). The resulting compound is sodium chloride (NaCl), also known as table salt.

Metal	Formula	Name
Sodium (Na)	NaCl	Sodium chloride
Magnesium (Mg)	MgCl2	Magnesium chloride
Aluminum (Al)	AlCl3	Aluminum chloride

Compounds Formed by Reaction with Oxide Ion

The oxide ion (O2-) is a common anion that is formed by the reaction of metals with oxygen gas. When a metal reacts with oxygen gas, it loses one or more electrons to form a cation, and the oxygen gas gains one or more electrons to form an oxide ion. The resulting compound is a salt that consists of the metal cation and the oxide ion.

For example, when calcium (Ca) reacts with oxygen gas, it loses two electrons to form a calcium cation (Ca2+), and the oxygen gas gains two electrons to form an oxide ion (O2-). The resulting compound is calcium oxide (CaO).

Metal	Formula	Name
Calcium (Ca)	CaO	Calcium oxide
Magnesium (Mg)	MgO	Magnesium oxide
Aluminum (Al)	Al2O3	Aluminum oxide

Compounds Formed by Reaction with Nitride Ion

The nitride ion (N3-) is a common anion that is formed by the reaction of metals with nitrogen gas. When a metal reacts with nitrogen gas, it loses one or more electrons to form a cation, and the nitrogen gas gains one or more electrons to form a nitride ion. The resulting compound is a salt that consists of the metal cation and the nitride ion.

For example, when lithium (Li) reacts with nitrogen gas, it loses one electron to form a lithium cation (Li+), and the nitrogen gas gains three electrons to form a nitride ion (N3-). The resulting compound is lithium nitride (Li3N).

Metal	Formula	Name
Lithium (Li)	Li3N	Lithium nitride
Magnesium (Mg)	Mg3N2	Magnesium nitride
Aluminum (Al)	AlN	Aluminum nitride

Conclusion

In conclusion, the table above shows the formulas and names of compounds formed by the reaction of metals with nonmetals. The compounds are formed by the reaction of metals with chloride, oxide, and nitride ions. The resulting compounds are salts that consist of the metal cation and the nonmetal anion. The formulas and names of the compounds are listed in the table above.

Introduction

In our previous article, we discussed the chemical formulas and names of compounds formed by the reaction of metals with nonmetals. We completed a table with the formulas and names of compounds formed by the reaction of metals with chloride, oxide, and nitride ions. In this article, we will answer some frequently asked questions about chemical formulas and names of compounds.

Q&A

Q: What is the difference between a chemical formula and a chemical name?

A: A chemical formula is a way of representing a compound using chemical symbols and numbers. It shows the number and type of atoms in a molecule. A chemical name, on the other hand, is a way of describing a compound using words. It is a more detailed and descriptive way of identifying a compound.

Q: How do I write a chemical formula?

A: To write a chemical formula, you need to know the number and type of atoms in a molecule. You can use the following steps:

Determine the number of atoms of each element in the compound.
Write the symbol of each element, followed by the number of atoms of that element.
Use subscripts to indicate the number of atoms of each element.
Use superscripts to indicate the charge on each ion.

Q: What is the difference between a cation and an anion?

A: A cation is a positively charged ion, while an anion is a negatively charged ion. Cations are formed when an atom loses one or more electrons, while anions are formed when an atom gains one or more electrons.

Q: How do I determine the charge on an ion?

A: To determine the charge on an ion, you need to know the number of electrons lost or gained by the atom. You can use the following steps:

Determine the number of electrons lost or gained by the atom.
Add or subtract the number of electrons from the atomic number of the atom.
The resulting number is the charge on the ion.

Q: What is the difference between a strong acid and a weak acid?

A: A strong acid is an acid that completely dissociates in water, while a weak acid is an acid that only partially dissociates in water. Strong acids have a high concentration of hydrogen ions (H+) in solution, while weak acids have a low concentration of hydrogen ions.

Q: How do I determine the pH of a solution?

A: To determine the pH of a solution, you need to know the concentration of hydrogen ions (H+) in the solution. You can use the following steps:

Measure the concentration of hydrogen ions in the solution.
Use the pH formula: pH = -log[H+]
The resulting number is the pH of the solution.

Examples

Example 1: Writing a chemical formula

Write the chemical formula for sodium chloride (NaCl).

Solution: The chemical formula for sodium chloride is NaCl, because it consists of one sodium atom (Na) and one chlorine atom (Cl).

Example 2: Determining the charge on an ion

Determine the charge on the ion formed by the loss of one electron by a sodium atom.

Solution: The atomic number of sodium is 11. When one electron is lost, the number of electrons becomes 10. The charge on the ion is +1, because the number of protons (11) is greater than the number of electrons (10).

Example 3: Determining the pH of a solution

Determine the pH of a solution with a concentration of 0.1 M hydrogen ions (H+).

Solution: Using the pH formula: pH = -log[H+], we get pH = -log(0.1) = 1.

Conclusion

In conclusion, chemical formulas and names of compounds are essential tools in chemistry. By understanding how to write chemical formulas and names, you can identify and describe compounds with ease. We hope this Q&A article has helped you to better understand chemical formulas and names of compounds.
