The Night Thoreau Spent in Jail is an exciting, poignant, accessible, and intellectually engrossing play in two acts, with several shifting and interpolated scenes from the real and imagined life of Henry David Thoreau (1817-62), the great nineteenth- century American author and poet-philosopher. The play is a dramatic representation of a vital moment in our history, in which the 29-year-old Thoreau?s ardent refusal to pay taxes?in protest to the United States government?s involvement in the Mexican War?landed him in prison in his home of Concord, Massachusetts. This famous act of civil disobedience?daring and unprecedented though it was? is merely the point of departure for Jerome Lawrence and Robert E. Lee?s widely

Emerson first sought an answer to the question of a man's place in a "science" of nature. His essay, Nature, was published in 1836, and is the main text by Emerson about transcedentalism. It is divided into 8 parts: 1. Nature A. It is an experience of solitude. B. We have to use the pleasure of nature with some moderation. 2. Commodity A. Nature is perfectly fitted for human beings. B. Nature is something which is alive and surrounds men and which is at their service; however, idndustry is not contradiction with nature: for him, both are complementary. 3. Beauty: He didvides it into 3 elements A. Beauty, as a pleasure in perceiving natural forms, as a relief for men. B. Beauty as "the mark God sets upon virtue." C. Beauty as an object of the intellect.

The periodic table is a very useful device for chemists and students to use. The periodic table is made of all of the elements that exist. For each element, the atomic number, atomic mass,the symbol, and the element name is in the periodic table. The Periodic table is organized in a way for us to easily tell which elements are metals, metalloids, or nonmetals. The state of the element is also sometimes included. The different groups (columns) have similiar characteristics with the other elements within the group. Group 1 is alkali metals, Group 2 is alkaline earth metals, Groups 3-12 are the transitional metals which also include the inner transition metals, Group 17 is the Halogens, and Group 18 is the noble gases.

Molecule Main article: Molecule A molecule is the smallest indivisible portion of a pure chemical substance that has its unique set of chemical properties, that is, its potential to undergo a certain set of chemical reactions with other substances. Molecules can exist as electrically neutral units unlike ions. Molecules are typically a set of atoms bound together by covalent bonds, such that the structure is electrically neutral and all valence electrons are paired with other electrons either in bonds or in lone pairs.

Periodic Table of Elements
Trend

Three Important Periodic Trends Definition of Periodic Trend: The tendency of a certain characteristic of an element to increase or decrease as they progresses along a period or group on the periodic table of elements Definition of Term Atomic Radius - One half the distance between the nuclei of identical atoms that are bonded together. Picometers (pm) Ionization Energy - The energy required to remove 1 electron from a neutral atom of an element. kiloJoules per Mole (kJ/mol) Electronegativity - The measure of the ability of an atom in a chemical compound to attract the electrons of another atom in the compound. Trend Across the PT The atomic radii decreases as you move across each period, as you add more protons to help pull the electrons closer to the nucleus.
