WebMolecules hold together because the valence electrons of the combining atoms form attractive forces, called chemical bonds, between the atomic nuclei. When atoms have gained or lost outer electrons, the chemical bond is called an ionic bond. When outer electrons are shared, the bond is called a covalent bond. Ionic bonds If the atom gains ... WebIn ionic compounds, electrons are completely transferred from one atom to another so that a cation—positively charged ion—and an anion—negatively charged ion—form. The …

Web26 jan. 2024 · Electrons in a σ s orbital are attracted by both nuclei at the same time and are more stable (of lower energy) than they would be in the isolated atoms. Adding electrons to these orbitals creates a force that holds the two nuclei together, so we call these orbitals bonding orbitals.

Web27 feb. 2024 · The atoms are joined together by a chemical bond.
