bonds‚ and carbon-carbon triple bonds. 2. The electronegativity of carbon (EN = 2.55) is too small to allow carbon to form C4- ions with most metals and too large for carbon to form C4+ ions when it reacts with nonmetals. Carbon therefore forms covalent bonds with many other elements. 3. Carbon forms strong double and triple bonds with a number of other nonmetals‚ including N‚ O‚ P‚ and S. Elemental Forms of Carbon: Graphite‚ Diamond‚ Coke‚ and Carbon Black Carbon occurs as a variety of allotropes

four forces: hydrogen bonding‚ hydrophobic bonding‚ ionic/hydrophilic bonding and disulfide bonding (Borges‚ 2014). Hydrogen bonds occur between polar‚ or charged amino acids. Hydrophobic bonds avoid water and occur between nonpolar amino acids. Due to their hydrophobic nature‚ these bonds often occur in the center of the structure and help pull it tightly together. Both the hydrogen and hydrophobic bonds are fairly weak‚ with hydrogen being the stronger of the two. Ionic bonds also known as hydrophilic

Bonds is something that retains and holds on together with one another. There are three major chemical bonds and they are‚ Ionic‚ Covalent‚ and Hydrogen bonds. An example of a covalent bond would be SCl^2 which is Sulfur dichloride. SCl^2 is a covalent bond because since they are close to each other in valence electrons‚ they have almost full outer shells so they share electrons with one another. A good example is table salt NaCl‚ because they are on opposite sides of the periodic table therefore

Classification of matter • All the objects and substances that we see in the world are made of matter. • This matter can be classified according to whether it is a mixture or a pure substance. • A mixture is a combination of two or more substances‚ where these substances are not bonded (or joined) to each other and no chemical reaction occurs between the substances. Examples of mixtures are air (a mixture of different gases) and cereal in milk. • The main characteristics
