ionic bonds are attractions between ions of opposite charge Flashcards
1
Q
what is an ion?
A
an atom or molecule with an electrical charge resulting from gain or loss of electrons
2
Q
what happens when an electron is lost? what happens when an electron is gained?
A
- when an electron is lost, a positive charge results
* when an electron is gained, a negative charge results
3
Q

A
an ionic bond
4
Q
what is an ion?
A
an electrically charged atom
*an atom that gains or loses electrons to become stable
5
Q
what is a cation?
A
a positively charged ion
*formed when an atom loses electrons
6
Q
what is an anion?
A
a negatively charged ion
*formed when an atom gains electrons
7
Q
what are ionic bonds?
A
an attraction between a cation and an anion
*formed when electrons are transferred from 1 atom to another atom
