WebAn ionic bond is formed when one atom donates electrons to another atom to form a positively charged cation and a negatively charged anion, which are held together by the electrostatic attraction between them. In contrast, a covalent bond is formed when two atoms share a pair of electrons, which results in the formation of a molecule. Web6 okt. 2024 · Ionic solids are held together by the electrostatic interaction of positive and negative ions. Chloride ions attract sodium ions, and sodium ions attract chloride ions. …
Covalent network solids (video) Khan Academy
WebCovalent network solids are composed of atoms covalently bonded together into a three-dimensional network or layers of two-dimensional networks. Due to the strength of the covalent bonds, covalent network solids have high melting points. Three-dimensional network solids (such as diamond or silica) are hard and rigid, whereas two-dimensional ... WebIonic bonds are the bonds which are always formed between a metal and a non-metal. For example:- Sodium atom has one electron in its outermost shell. Sodium is a metal. Every atom of an element wants to have 8 electrons in its outermost shell/orbits/energy levels excluding some elements like hydrogen and helium because they need 2. diashow hintergrundmusik
