It’s a national disgrace than nearly 50 million of our American neighbors live in homes that can’t afford enough food. This compelling film explains why we have this problem‚ and‚ most importantly

Subject: Chemistry Topic: The Periodic Table The periodic table is a classification of all the elements based on ATOMIC NUMBER. It is composed of HORIZONTAL PERIODS and VERTICAL GROUPS which contain the elements arranged: *the order of INCREASING ATOMIC NUMBER *in the relation to the ELECTRON STRUCTURE of the atoms *in the relation to their CHEMICAL PROPERTIES (Criteria Used For Placing ELEMENTS in the Periodic Table) 1. ATOMIC NUMBER 2. NUMBER OF SHELLS (PERIOD) 3. NUMBER OF OUTER

Acids and Bases Shane Purpose- To study the relationship between pH and metabolism. 10/21/13 Materials- see attached Per. D Biology Procedure- see attached Data and Results- see attached Theory- PH stands for the power of hydrogen. People refer to the pH scale as a tool for finding out if a substance is acidic‚ basic‚ or neutral. This scale goes from zero to fourteen. The number seven is neutral. Any number higher than seven on this scale is basic. Any number lower is acidic

Atomic radii • Ingoing from top to bottom of a group‚ the outermost electrons are assigned to orbitals with increasingly higher values of the principal quantum number. The underlying electrons require space so the electrons of the outer shell is farther from the nucleus. • In a period‚ going across the period‚ a proton is added to each nucleus and an electron is added to each outer shell. In each‚ the effective nuclear charge increases slightly because the effect of each additional proton is more
