Chemical Bonding: Ionic Bonding

Explanation
Atoms are composed of protons, neutrons, and electrons. Protons have a positive charge, electrons have a negative charge, and neutrons have no charge. The positive charge of the protons is balanced by the negative charge of the electrons, resulting in an overall neutral charge for the atom. Therefore, atoms do not have a charge.

Explanation
Electrons have a negative charge. This is because electrons are subatomic particles that orbit around the nucleus of an atom, and they carry a negative electrical charge. The negative charge of electrons is equal in magnitude to the positive charge of protons, which are found in the nucleus of an atom. This balance of positive and negative charges allows atoms to remain electrically neutral overall.

Explanation
Valence electrons are the outermost electrons in an atom that participate in chemical reactions and determine the atom's reactivity. These electrons are located in the outermost energy level or shell of an atom and are involved in forming chemical bonds with other atoms. The term "valence" refers to the combining capacity of an atom, and valence electrons play a crucial role in the formation of chemical compounds.

Explanation
When an electron is added to or removed from an atom, the atom becomes an ion. This is because the addition or removal of an electron results in a change in the atom's overall charge. If an electron is added, the atom becomes negatively charged and is called an anion. If an electron is removed, the atom becomes positively charged and is called a cation. In both cases, the atom has gained or lost an electron, resulting in the formation of an ion.

Explanation
Ionization is the process of removing or adding electrons. When an atom or molecule gains or loses electrons, it becomes charged and is called an ion. This process can occur through various means such as heating, chemical reactions, or exposure to radiation. Ionization plays a crucial role in many scientific and technological processes, including the creation of plasma, the operation of ion engines, and the formation of ions in the Earth's atmosphere.

Explanation
Positively charged ions, called cations, are formed when an atom loses electrons. This loss of electrons creates an imbalance between the number of protons and electrons, resulting in a net positive charge. Anions, on the other hand, are negatively charged ions that are formed when an atom gains electrons. Therefore, the correct answer is cations.

Explanation
Anions are negatively charged ions that result from the gain of electrons. When an atom gains one or more electrons, it becomes negatively charged and forms an anion. This occurs because the atom now has more electrons than protons, giving it a net negative charge. Cations, on the other hand, are positively charged ions that result from the loss of electrons. Therefore, the correct answer is anions.

Explanation
An ionic bond forms when a cation, which is a positively charged ion, transfers its extra electron to an anion, which is a negatively charged ion, who needs it. This transfer of electrons creates a strong electrostatic attraction between the cation and the anion, resulting in the formation of an ionic bond. Ionic bonds typically occur between metals and nonmetals, where the metal loses electrons to form a cation and the nonmetal gains electrons to form an anion. This transfer of electrons allows both ions to achieve a stable electron configuration and results in the formation of a compound with a neutral overall charge.

Explanation
Ions of opposite charge attract each other easily, causing them to form a specific pattern known as a crystal lattice. This attraction is due to the electrostatic force between the positive and negative charges of the ions. The opposite charges attract each other, resulting in the formation of a stable and organized arrangement.

Explanation
Ionic bonds occur between a metal and a nonmetal. In an ionic bond, the metal atom loses electrons to become a positively charged ion, while the nonmetal atom gains those electrons to become a negatively charged ion. This electrostatic attraction between the oppositely charged ions forms the ionic bond. Therefore, the correct answer is nonmetals.
