Introduction to Ionic Bonding and Covalent Bonding

These bonds are Ionic and Covalent. Even though these are the most common kinds of bonds they can both be subcategorized and divided into many other kinds of bonds. These subcategory bonds include polar covalent, hydrogen bonds, double covalent, triple covalent, coordinate covalent, network covalent, and metallic bonds. If one wants to familiarize themselves with these three types of bonds one must first understand the properties of electrons. Electrons have an outermost layer, which acts as a sort of shell that shields the nucleus. If all of the energy levels in the atom are full populated with electrons, it is said to be stable, and in most cases, is therefore unreactive. Examples of this include the noble or inert gases such as neon or argon. However if the outer energy level of the atom is not stable, it will automatically try to either gain or lose electrons to become stable.

This is achieved by an ionic reaction. Ionic bonding occurs when the outer atoms of on material changes orbit and joins another material for example: Sodium chloride As you can see, sodium is a group one metal it has one electron on its outer energy level so is therefore unstable.

It is essential that we know what bonds are before we can understand any chemical reaction.

To understand bonds, we will first describe several of their properties. The bond strength tells us how hard it is to break a bond. Bond lengths give us valuable structural information about the positions of the atomic nuclei. Bond dipoles inform us about the electron distribution around the two bonded atoms. From bond dipoles we may derive electronegativity data useful for predicting the bond dipoles of bonds that may have never been made before. From these properties of bonds we will see that there are two fundamental types of bonds--covalent and ionic. Covalent bonding represents a situation of about equal sharing of the electrons between nuclei in the bond.

Covalent bonds are formed between atoms of approximately equal electronegativity. Because each atom has near equal pull for the electrons in the bond, the electrons are not completely transferred from one atom to another.

The chemical bond found in tetrodotoxin is a covalent bond, which are bonds that share electrons. As mentioned in the case description, tetrodotoxin is a molecule that blocks voltage-gated sodium ion channels.

Describe the structure of a sodium ion. The sodium ion has eleven protons and ten electrons, indicating that the first orbital shell has two electrons and the second shell has eight electrons 1s2 2s2 2p6 5. Fluorine 9 [He]2s22p5 4. Next we consider the sizes and shapes of organic molecules and how structural formulas written in two dimensions can be translated into three-dimensional models that show the relative positions of the atoms in space.

We also discuss models that reflect the relative sizes of the atoms and the way in which the atoms may interfere with each other when in close quarters steric hindrance. Then we go on to further important aspects of structure-the functional group concept and position isomerism. Our aim is to have you become more familiar with the various kinds of organic compounds and begin to see how the practicing organic chemist visualizes molecules and correlates the diverse kinds of structures that he has to deal with in his work. The two-electron bond, which is illustrated by the carbon-hydrogen bonds in methane or ethane and the carbon-carbon bond in ethane, is called a single bond. In these and many related substances, each carbon is attached to four Chronic long-term occupational exposure to hydrochloric acid has been reported to cause gastritis, chronic bronchitis, dermatitis, and photosensitization in workers.

Prolonged exposure to low concentrations may also cause dental discoloration and erosion. Hydrochloric Acid is a strong chemical compound. It is a powerful substance with many uses. The bonding in hydrochloric acid is the reason why it has a high The two elements making up hydrochloric acid are Hydrogen and Chlorine. Each molecule of hydrochloric acid is made up of one Hydrogen atom and one chlorine atom sharing one electron each so that they both have a full outer shell. Hence the Molecular Formula of hydrochloric acid is HCl.

Hydrogen has an electronegativity of 2. Therefore the difference in electronegativity is 1. This means that hydrochloric acid is a polar compound. A polar covalent bond occurs when there is a significant difference in the electronegativity values for the two bonded atoms. The bonding electron pair is drawn toward the more electronegative element in the bonded pair, leaving the other with a slight positive charge.

Figure Transport Phenomenon Electrical and Thermal in two allotropic forms of Carbon Diamond and Graphite Graphite and Diamond both are formed from carbon two allotropic forms of carbon. Though they have similar constituent element, they differ a lot in their properties. Diamond is a good thermal conductor but a bad electrical conductor, while graphite is a bad thermal conductor but a good electrical conductor.

This is one example of their property difference. The difference in their properties arises because of different arrangement of carbon atoms present in them. Basic physical and chemical properties of graphite and diamond to highlight their differences are as follows: Differences between Graphite and Diamond Physical Appearance: Graphite is opaque and metallic- to earthy-looking while diamonds are transparent and brilliant. Another important physical difference is their hardness.

The hardness of minerals is compared using the Moh's Hardness Scale, a relative scale numbered 1 softest to 10 hardest. Graphite is very soft and has a hardness of 1 to 2 on this scale. Diamonds are the hardest known natural substance and have a hardness of Diamond is used as an abrasive because of its great hardness, whereas graphite is used as a lubricant. Chemistry of Life Matter is anything that occupies space. Matter is made of one or more elements. An element is the most pure form of matter. Elements are made of atoms. There are elements and of these 92 are naturally occurring.

Essential Elements About 25 elements are essential to life. These are O, C, H and N. Trace Elements Certain elements are needed in trace amounts. These are also essential to life. The human body needs trace amounts of boron, chromium, iron, iodine, etc. Humans need 0. If iodine is deficient or in excess, a goiter develops — due to malfunctioning of the thyroid gland. Outside of the nucleus are the electrons. Electrons have a negative charge. The number of electrons is equal to the number of protons: so negative charges cancel out the positive charges.
