These crystalline solids can be dissolved in water or other polar solvents. Ionic compounds are solid and good conductors of electricity (Ophardt, 2003).
Additionally, ionic bonds are formed when a metallic element gives up one or more electrons thus forming a positive ion. A positive ion is also known as a cation and has a stable electron configuration. Cations enter non-metallic elements and cause it to become a negative electron. These negative electrons are also known as anions and also have a stable electron configurations. Electrostatic forces attract cations and anions to each other. Examples of ionic compounds include calcium chloride, CaCl2, and potassium oxide, K2O (Clark, 2000).
Covalent bonds, on the other hand, do not give up, gain, or transfer electrons, but rather share electrons equally. Covalent bonds form between atoms in a compound when atoms have a similar ability to gain and/or lose ions. While ionic bonds are formed between metals and non-metals, covalent bonds are formed by combining non-metals. Covalent bonds require that molecules exist in their true form. Electrostatic forces are not present among covalent molecules. Covalent molecules exist in liquid and gaseous forms at room...
When one atom gives up or loses an electron, the atom will reduce in size. When an atom gains or receives an electron, the atom will grow in size. Ionic bonds lead to the formation of crystalline solids with high melting points and can be dissolved in water and other polar solvents. The ionic compounds formed through bonding are always solid and are good conductors of electricity. Ionic bonds are

Mixtures are composition of two or more substances which are not chemically combined and do not exist in fixed proportions to each other. For instance when you take two components, an iron
Mixture a Compound Mixture and a Compound Three main terms are usually used in the field of chemistry. These are element, compound and a mixture. These three will be the element of key discussion in the paper. There is a great difference between a mixture and a compound. A compound is formed from two elements that combine together chemically by sharing electrons. The physical and chemical properties of the constituent elements are
Physical Science Grade Course Describe the difference between a mixture and a compound For basic understanding, a mixture comprises of two or more different substances which are not chemically combined to each other. On the other hand, a compound consists two or more chemically bonded different substances which are present in a fixed ratio. In other words, the difference between a mixture and a compound is evident from the mentioned definitions. Furthermore, there are

An overview of mixtures, compounds, and the processes of identifying them Describe the difference between a mixture and a compound The standard definition of a mixture is a substance in which two or more
abundant elements that occur in living organisms are as follows: carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorous. These and all elements are made up of atoms, which are the primary units of matter. Molecules are groups of atoms that are covalently bonded. Covalent bonds occur when two atoms share one or more pairs of electrons. This is different from ionic bonds, which arise when an electrical attraction between two
