. Groups are arranged vertically in the table and atoms in the same group have the same number of electrons in the outer orbital. The periodic table tells you several key facts about the atom such as atomic weight, atomic number(number of protons), and name of the atom. The periodic table is also arranged into several property groups. ● Group 1: Alkali Metals ● Group 2: Alkali Earth Metals ● Group 312: Transition Metals ● Group 14 or 3A: Boron Group ●

First digestion problem I found was gallstones. The gallbladder is one of the body’s smallest organs. Located right below the liver, it collects bile, necessary for the digestion of fat, and releases it into the small intestine. When excess cholesterol is present in bile, stones can begin to form in the gallbladder – leading to excruciating pain, infection and other complications According to (The dr. oz show , 2010) gallstones, caused by the crystallization of excess cholesterol in the bile,

dioxide is exhaled by the lungs and the hydrogen is transported to the site of electron transport chain. Electron transport chain: The hydrogen molecule that is formed via the Krebs cycle is transported to the mitochondria where it is split into a proton and an electron. These electrons then form a redox reaction which release large amounts of energy which is needed to resynthesis ATP and form 32 molecules. Training: Athletes who train regularly can increase the efficiency of their oxygen transport

things are highly organized, from the smallest part to the largest. On the chemical level: atoms make up elements. Each element has a specific number of electrons that orbit the nucleus. In the center of the element, the nucleus has protons and neutrons. The number of protons in an element is always equal to the number the electrons. The number of neutrons may vary to make isotopes of that element. Elements come together to give up, accept or equally share electrons to make molecules. The smallest part

brewer named Soren Sorensen in 1909. He was searching for a convenient means of checking the acidity of his alcoholic product to prevent its spoilage by bacterial action. (Human Anatomy and Physiology; Seventh Edition ) Acids are proton donors while bases are proton acceptors. Referring to the pH scale numbers zero to fourteen, stomach acid and lemon juice are examples of strong acids having a pH of one and two while ammonia is an example of a base having a pH of 12. Milk and water are considered

“Nature is our kindest friend and best critic in experimental science if we only allow her intimations to fall unbiased on our minds” -Michael Faraday Knowledge of science is an ever-growing tree as it never stops and advancements are always made. The scientific revolution is an example of a period of major growth in scientific advancements, starting at the end of the Renaissance and ending near the late 18 century. However, the expansion of scientific knowledge did not stop at the end of the scientific

Isotopes are “any of two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number, but having different numbers of neutrons in the nucleus, or different atomic weight” (Dictionary.com). There are many different isotopes in this world, some more common than others. Krypton 85 and Copper 67 are just two of many other isotopes. Krypton has a very high boiling and melting point, at 153.4° C for boiling point and 157° C for a melting point (Chemistry
