A bond formed between atoms when one atom would become positive and the other negative?


Question: A bond formed between atoms when one atom would become positive and the other negative?

The bond formed between atoms when one atom would become positive and the other negative is called an ionic bond. Ionic bonds are formed when one atom transfers an electron to another atom. The atom that loses the electron becomes a positively charged ion, called a cation. The atom that gains the electron becomes a negatively charged ion, called an anion.

Ionic bonds are typically formed between metals and nonmetals. Metals tend to have few electrons in their outermost valence shell, while nonmetals tend to have many electrons in their valence shell. This makes metals more likely to lose electrons and nonmetals more likely to gain electrons.

For example, sodium (a metal) has one electron in its valence shell. Chlorine (a nonmetal) has seven electrons in its valence shell. When sodium and chlorine come together, sodium will transfer its one electron to chlorine to achieve a full valence shell. This will create a sodium cation (Na+) and a chloride anion (Cl-).

Ionic bonds are very strong and stable. This is because the oppositely charged ions are attracted to each other by electrostatic forces. Ionic bonds are responsible for the formation of many common compounds, such as table salt (NaCl) and magnesium oxide (MgO).

Here are some other examples of ionic compounds:

  • Calcium chloride (CaCl2)
  • Potassium bromide (KBr)
  • Lithium fluoride (LiF)
  • Aluminum oxide (Al2O3)
  • Magnesium sulfate (MgSO4)

Ionic compounds are typically hard and brittle solids with high melting and boiling points. They are also good conductors of electricity when dissolved in water or melted.

Ionic bonds play an important role in many biological processes, such as nerve conduction and muscle contraction. They are also used in many industrial applications, such as the production of batteries and fertilizers.
