Chapter 6 - Answer Key to Section Review 1-3 Section Review 1 1. What is the main distinction between ionic and covalent bonding? Answer (A): Ionic bonding involves the electrical attraction between large numbers of anions and cations. Covalent bonding involves the sharing of electron pairs between two atoms. Translation: -Ionic bonding happens between a metal and a non-metal (east coast and west coast) -One atom completely donates its valence electrons to another atom -Metals

Family Values Over all The relationship between the family members in the play can give the reader motives for how some of the characters might act. The characters in Macbeth inspire each other to commit certain actions and without some character shaving the personality they possess such as Lady Macbeth or Macduff the story would have been far less exciting. In this story the relationships amongst members of different families is not strong. family plays a major role

The folk tale known as The Tumor Doubled aims to influence our understanding of moral values‚ like many other folk tales. In this tale specifically‚ it is implied that a negative intentionally leads to negative consequences; likewise‚ good intentions lead to positive consequences. The folk tale shows the relationship between intentions and consequences by illustrating two priests. The first priest‚ by mere chance‚ ends up sleeping at a shin‚ where many demons gather for drinking and dancing. The

bub Weather is the state of the atmosphere at a given time and place‚ with respect to variables such as temperature‚ moisture‚ wind velocity‚ and barometric pressure. Weather can be classified as day to day temperature and precipitation activity‚ where climiate is average atmospheric conditions over longer periods of time. Weather occurs from temperature and moisture differences between one place and another. These differences can occur due to the sun angle at any particular spot. The strong

Intermolecular Bonding Essay Write an essay on intermolecular bonding. Explain how each type of bond arises and the evidence for the existence of each. Comment on their strengths in relation to the types of atoms involved; the covalent bond and relative to each other. Use the concepts of different types and strengths of intermolecular bonds to explain the following: There exists four types of intermolecular bonding‚ they include ionic‚ covalent‚ Van der waals and hydrogen bonding. In order to describe

Gay Marriages and Family Values At the very heart of the debate about same-sex marriage is the definition of the word "marriage". To some people‚ it changes to meet social and economic needs‚ to others it remains firmly fixed. In traditional cultures of Asia‚ arranged marriages are the rule.

The Anglo-Saxons saw marriage as a strategic

Carbon is crystallized in super heat and pressure in the boiling magma. Even apart from its rarity and value‚ diamond is a remarkable mineral (Murck‚ B. W.‚ Skinner‚ B. J.‚ & Mackenzie‚ D. (2008). Diamonds are pure elemental carbon‚ the same chemical found in graphite and charcoal. Carbon-12 is the most important atom living in beings‚ besides being the

Covalent Bonding In a covalent bond‚ a pair of electrons is shared between two atoms. Each of the positively charged nuclei is attracted to the same negatively charged pair of electrons. The diagram: A and B are held together by this shared attraction. Covalent bonds are often drawn as dots and crosses diagrams to show that the electrons have come from two different atoms. Molecules have a certain fixed number of atoms in them joined together by covalent bonds. Examples: Bonding in hydrogen

HYDROGEN BONDING: Hydrogen bonding is a bonding type consisting of dipole and dispersion forces. A hydrogen bond is the attractive force between a hydrogen atom attached to a molecule and an atom of a different molecule. According to the Pauling scale of electro-negativities of the elements‚ it can be viewed that the three most electronegative elements in the periodical table are nitrogen‚ oxygen and fluorine. These are also called heteroatoms. The heteroatoms have a partial negative charge while
