Chemical bonding

member of large gaseous, liquid, or solid chemical compounds whose molecules contain carbon. A polyatomic ion compound are made up of two or more atoms bonded together and a metal. A binary compound is a chemical compound that contains exactly two different elements. These two differ because polyatomic are made up of two or more atoms while binary compounds contain exactly…

one elements? Group one elements are alkali metals. The physical properties of group one elements are that they are shiny and the alkali metals are very soft. Lithium is the hardest alkali metal and they become softer as you go down the group. The chemical properties of group one is that they’re very reactive when mixed with water or when in contact with the air. Each element in group one has one electron in their outermost shell. Also, group one elements get more reactive as you go down; this…

cycle, with weather influencing the way the water moves through the earth. Chapter 15 “The Ladder of Life” All living organisms follow the same ladder of life. . “ All living things are made of cells the chemical factories of life.” (Hazen & Trefil 252). But it goes even further than that, chemical Compounds, microscopic cells, cells to organs, to organ systems and then organisms. Even then organisms are categorized by kingdom ,phylom, class, order , family, genus, species. Everything living…

Research Question How does the increase of concentrated hydrochloric acid affect the rate of the chemical reaction with sodium thiosulphate? Background to the Research question Chemical reaction involves the chemical change of atoms and molecules, it will occur when two or more molecules interact with each other and the molecule will change. Thus, bonds between atoms are broken down and then new molecules are formed. Hydrochloric Acid and Sodium thiosulfate are both colourless and clear…

A covalent chemical bond is a link that contains electrons which are shared between two atoms. 9. A polar bond is where the electrons forming the bond are not distributed equally between the two atoms of the bond. A nonpolar bond shares a pair of electrons with each…

synthesizing a drug is very hard to completely control but can be managed through the use of several organic chemistry principles. Chemical synthesis can be sped up by using catalysts to reduce the activation energy required to break and reform the bonds of molecules. Pseudoephedrine is a great example to show how factors such as polarity, functional groups and bonding sites can be used to increase the performance of a drug as well as reducing the amount of side effects. During the actual…

Introduction Lead (Pb) contamination is a pervasive issue in many low-income neighborhoods throughout the United States. The toxicity of lead poses significant risks to human health, and proves to be especially harmful for children in terms of cognitive and physical development. Lead in the environment is primarily related to a legacy of anthropogenic sources including leaded gasoline, leaded paint, and various industrial applications. Although the presence of heavy metals is ubiquitous in the…

negative end of another polar molecule. These are the forces that bond the electronegative polar oxygen molecule with the positive polar hydrogen molecule. Dipole-dipole forces account for water being attracted to most substances (adhesion). Hydrogen bonding accounts for water being attracted to other water molecules…

Gilbert Lewis first introduced his theoretical dot structures in 1916. Today, these same dot structures are used to illustrate the chemical bonding nature of atoms. How did Lewis formulate these brilliantly simple representations of nature? The Lewis Dot Structures we know today actually derive their functionality from Lewis’ own model of the atom, the Theory of the Cubical Atom. This essay will explore the functionality of Lewis’ cubical atom and how this model led to the Lewis Dot Structures.…

supplement. A deficiency in zinc can cause growth retardation, delayed sexual maturation, eye and skin lesions, hair loss, and an increased risk of illness and infection. Zinc is one of the many ions that function as an enzyme cofactor. Every chemical reaction in the body requires an enzyme. Enzymes are biological…
