WebTo form an ionic bond, a halogen atom can remove an electron from another atom in order to form an anion (e.g., F-,Cl-, etc.). To form a covalent bond, one electron from the halogen and one electron from another atom form a shared pair. For example, in H–F, the dash represents a shared pair of valence electrons, one from H and one from F. WebUNIT 3 When an element loses its valence electrons to form a cation, it assumes the electronic structure of the preceding noble gas. Ionic compounds are composed of both positive cations and negative anions and bear a neutral overall charge Metals and non-metals are joined by ionic bonds. Molecular compounds are usually formed when a …

WebThe number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms. This outermost shell is known as the valence shell, and the electrons found in it are called valence electrons. WebJul 20, 1998 · 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 … covalent bond, in chemistry, the interatomic linkage that results from the sharing of … WebIonic bonds happen because of the ____ of valence electrons. answer choices sharing transfer keeping covering Question 9 45 seconds Q.
