Ionic bond

with the nucleus, a dipole moment develops. Ionic polarisation To undergo ionic polarisation, a material must have an ionic structure i.e. it must be composed of cations and anions. This ion pair (cation and anion) already possesses a dipole moment before the application of an electric field, however the sum of dipole moments over the entire material (i.e. net polarization) may still be zero. When electric field is applied it causes the ionic bond to stretch. If the material possessed a…

relatively strong peptide bonds in the primary structure. Some of the factors resulting in the denaturation of proteins are heat and change in pH or potential of hydrogen. An increase in temperature will disrupt the weak forces of attraction between the R groups such as hydrogen bonds, Van der Waales forces and induced dipole-induced dipole attractions. The application of heat on the protein will increase the kinetic energy of the molecules leading to the breakage of the bonds. Thus the…

n-Pentanol is capable of hydrogen bonding, in reference to it's size the majority of the molecule does not hydrogen bond, where as Methanols ability to hydrogen bond is significant in reference the molecules small size. 2. Methanol was the only substance that NaCl would not completely dissolve in. Water is the only substance that completely dissolved NaCl. NaCl is formed by an ionic bond, meaning it has strong Ion-Dipole forces. Water can dissolve NaCl because the slightly positive…

The elements sodium and chlorine show emergent properties, because when sodium is alone it's just a metal and chlorine is a poisonous gas. When you combine the two with an ionic bond the emergent properties are shown, because they come together to form table salt, but on their own this wouldn't be possible. 2.1.2) Yes, even though organisms only require it in small amounts it is still essential because it contributes to the organism's development. 2.1.3) If a person has an iron deficiency it…

Aha Thesis The purpose of this unity was to learn how new substances formed and what happened when they are formed. Some of the key ideas addressed in this unit are: chemical and physical reactions, the law of conservation of mass, and ionic/covalent bonding. In a chemical reaction, something new is created, different from what created it, a new substance is formed. In a physical reaction, the appearance of the object is changed, but nothing new is created. An example of a chemical…

There are four types of interactions that stabilize a protein and give it structure at the tertiary level. Hydrophobic interactions are nonpolar molecules, they generally have a long chain of carbons that do not interact with water molecules. RGroups prefer to interact with each other internally and away from water (Wolfe, G. (2000). Thinkwell biochemistry - 2.7.4 Tertiary Structure). This interaction contributes significantly to the folding and shaping of a protein. Hydrophobic interactions…

Single Replacement Reactions and Double Replacement Reactions A chemical reaction is a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction. The evolution of energy as heat and light, production of gas, formation of a precipitate, and color change are 4 indicators of a chemical reaction. Two out of the six types of reactions are the single and the double replacement reactions. During single…

that can replace conventional metals and ionic-bonded oxide ceramics such as alumina. Structure of Silicon carbide Silicon carbide is a compound of silicon, a metalloid, and carbon, a nonmetal, and has a giant molecular lattice structure. It has a similar structure with diamond. Each carbon atom is joined tetrahedrally to four silicon atoms by strong covalent bonds, and each silicon atom is joined tetrahedrally to four carbon atoms by strong covalent bonds. This network is repeated and forms a…

a compound, identifying a chemical compound is not as daunting as it may seem. There are three main types of chemical compounds: metallic, covalent, and ionic compounds.2 In this experiment, however, the unknown compounds are specifically ionic. An ionic compound is made up of a metal atom and a nonmetal atom. When a metal atom ionically bonds to a nonmetal atom, the metal atom transfers one or more of its electrons to the nonmetal atom, causing the metal atom to become a…

are important because the chemical behavior of an atom depends on it. 9. Chemical Bond: an attraction between two atoms resulting from a sharing of outer shell electrons or the presence of opposite charges on the atoms. The bonded atoms gain complete outer electron shells. Covalent Bond: a type of strong chemical bond in which two atoms share one or more pairs of valence…
