How is an ionic bond formed?
An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation—a positively charged ion. The atom gaining one or more electron becomes an anion—a negatively charged ion.
An ionic bond is the force of attraction that holds together oppositely charged ions. It forms when atoms of a metal transfer electrons to atoms of a nonmetal. When this happens, the atoms become oppositely charged ions. Ionic compounds form crystals instead of molecules.
Ionic bonds result from the electrostatic attraction between oppositely charged ions, which form when valence electrons are transferred from one atom to another.
ionic bond (definition) bond formed when one or more electrons are transfered from one atom to another. ionic bond (description) a chemical bond resulting from the attraction between oppositely charged ions.
A bond is ionic if the electronegativity difference between the atoms is great enough that one atom could pull an electron completely away from the other one. That situation is common in compounds that combine elements from the left-hand edge of the periodic table (sodium, potassium, calcium, etc.)
Ionic bonds form when ions share electrons.
ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.
Ions are formed when the number of protons in an atom does not equal the number of electrons. An ion therefore is an atom that has gained or lost one or more electrons and therefore has a negative or positive charge. Ionization is the process of exchanging electrons among atoms or molecules.
Which pair of elements is most likely to form an ionic compound? Metals and nonmetals tend to form ionic bonds.
How do ions form ionic bonds? Two atoms come together to share their electrons. Ions of opposite electrical charges are attracted to each other to balance the charges. One atom swaps all of its negative electrons for all of the other atom's positive protons.
What makes up an ionic compound quizlet?
An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions.
Which statement best describes an ionic bond? An ionic bond involves a metal that transfers one or more electrons to a nonmetal.
Key Takeaways
Ionic compounds have high melting points. Ionic compounds are hard and brittle. Ionic compounds dissociate into ions when dissolved in water.
An example of an ionic bond is the bond in sodium chloride, which is salt. Sodium's valence electron is transferred to the outer electron shell of chloride. Molecules with ionic bonds form ionic compounds.
Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom. The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion (anion).
Think of forming an ionic compound as three steps (this is a simplification, as with all models): (1) removing an electron from the metal; (2) adding an electron to the nonmetal; and (3) allowing the metal cation and nonmetal anion to come together.
