Chemical Principles For Pharmacy Technicians

5. The two primary types of chemical bonding is ionic and covalent. Ionic bonding is when atoms give

An ionic bond is a bond that results from the attraction between oppositely charges ions; one atom "gives" another atom an electron. Combinations of metals and nonmetals typically form ionic bonds. A covalent bond is a bond that results from

A covalent bond is a bond that occurs when atoms in a molecule share a pair of electrons. For example, “the atoms in sugar do not form ions; instead, they are held together because of shared electrons.”

Surface Tension: The measure of how difficult it is to stretch or break the surface of a liquid.

2. Describe the three different types of bonds, providing examples of molecules formed through each type of bond. (3 points) Covalent bond, methane. Ionic bond, table salt. Hydrogen bond, water.

What special bond (in water) opposes water’s molecular movement when water absorbs energy requiring water to have more heat added to raise its temperature? Hydrogen Bond.

A greater number of electrons correspond to a great polarizability of a molecule. Greater polarizability leads to greater dispersion forces. Thus, as molar mass increases, the number of electrons increase, which increases the polarizability of the molecule and hence the strength of the dispersion forces of the substance.

A) They feature carbon atoms which are covalently bonded to hydrogen (Open Learning Initiative, 2015, pg.63).

Moles – an amount of material (atoms, ions or molecules) that contains Avogadro’s number (6.022 x 1023) of particles.

A London dispersion force is the name given to intermolecular forces in a non-polar compound. It greatly depends on the amount of electrons in a molecule. The larger/ heavier molecules have more electrons resulting in a greater attractive London force. This is because as the external force causes a temporary shift, the electrons will move to one side and it will become more negative resulting in a greater attraction. Then it will return to its previous state of the dispersion of

35. Polyatomic ions (Table E) are groups of atoms, covalently bonded together, with an overall charge.

Ionic and Covalent Bonding Ionic and covalent bonding is involved when the atoms of an element chemically combine to make their outer shells full and to make the atoms stable. The first type of bonding you can get is ionic bonding. Electrons are transferred from one atom to another to try and create full outer shells, this gain and loss of electrons on the atoms results in positive and negative ions. In these compounds you get electrostatic force, this is the force/attraction that occurs between the positive and negative ions that hold the compound together.

https://en.wikipedia.org/wiki/Neutralization_(chemistry) An acid is molecule or ion capable of donating a hydron, or capable of forming a covalent bond with and electronic pair.https://en.wikipedia.org/wiki/Acid A base in chemistry, is a substance that can accept hydrogen ions.https://en.wikipedia.org/wiki/Base A covalent bond can also be known as a molecule bond, is a chemical bond that involves the sharing of electron pairs between atoms. https://en.wikipedia.org/wiki/Covalent_bond These electron pairs can also be known as shared pairs or bonding pairs. Electron pairs consist of two electrons that occupy the same orbital but they have opposite spins. Hydrogen ions is a common name for the aqueous cation H 30+, the type of oxonium ion made by protonation of water. It's the positive ion present an Arrhenius acid is dissolved in

Within each one of the songs, the solos or leads created a bond to bond. Each molecular formula was different and causes different experience for the electrons. Some polar covalent, some nonpolar covalent, and some ionic, but together they all competed for popularity with Natural Neon. They all either shared or transfer to trump Natural neon. Each element had a quick thing to say. Natural neon told us that he was not at all sad about being kicked off his Octet rule podium. He was glad to see everyone becoming stable. Needy Nitrogen and Coping Carbon were very pleased to become bonded. They could be held together by a couple of intermolecular forces, Dipole-Dipole, Hydrogen bonding, or London dispersion. They were glad they were living a molecular compound life. Happy Hydrogen and his backup guitar player, Lite Lithium was so excited about their song. On Performance day, Lite Lithium lost his guitar pick, so Happy hydrogen transferred him his. But he was still upset because it could not get its Lewis Dot Structure. This song was still great because it was an ionic compound. Last, Lite lithium would like to show his heat of vaporization and Thermal Conductivity. He was a one act show with the help of himself. The moral of the story is that just because there are standard set that are unreachable by yourself, does not mean they are reachable with the help of your friends and Chemical

In a gas, the molecules have enough kinetic energy so that the effect of intermolecular forces is small (or zero for an ideal gas), and the typical distance between neighboring molecules is much greater than the molecular size. A gas has no definite shape or volume, but occupies the entire container in which it is confined.
