in which it becomes a liquid metal. This is caused when immense amount of pressure is added to it such as when it’s found in gas like planets including Jupiter and Saturn. Hydrogen consists of 3 isotopes including hydrogen-1‚ known as protium‚ hydrogen-2‚ deuterium‚ and hydrogen-3‚ tritium. The first isotope if the most abundant one‚ while the third one is the least. Henry Cavendish‚ an English scientist who developed hydrogen by mixing zinc along with hydrochloric acid‚ first identified it as a distinct

a) I definately agree with this statement and how science is ever changing. The scientific method begins by asking a question about something. After asking a question the next step is to form a hypothesis or educated guess. A repeatable expieriment is then created to test said hypothesis‚ and a large amount of data is collected. Data collection then leads Scientits to analyze the data and come up with a conclusion to see if the hypothesis was proven correct or incoreect. If the hypothesis is proven

0 and 1.8 = Polar Covalent‚ ~0 = Nonpolar covalent • Moles = Mole * (Number of electrons in element/ 1 mole) • Atoms = Moles * 6.02*10^23‚ Mass number (Z) is the sum of protons plus neutrons • Isotopes of an element have the same number of protons‚ but different numbers of neutrons. • Isotopes of an element have the same number of protons‚ but different numbers of neutrons. • As bond order increases‚ bond length decreases. As bond order increases‚ bond strength increases • Allotropes:

An Investigation in Monoclonal Antibodies Meena Henen Introduction One of the major medical concerns of the century has been finding a cure for cancer. Scientists have made progress in solving the cancer puzzle with the innovation of procedures such as chemotherapy and various scanning methods‚ but no one has yet found a definite solution. Possibly the newest discovery in the cancer field has been monoclonal antibodies (mAbs). Nicknamed “magic bullets‚” mAbs have

INTRODUCTION Protons and neutrons make up a nucleus‚ which is the foundation of nuclear science. Fission and fusion involves the dispersal and combination of elemental nucleus and isotopes‚ and part of nuclear science is to understand the process behind this phenomenon. Adding up the individual masses of each of these subatomic particles of any given element will always give you a greater mass than the mass of the nucleus as a whole. The missing idea in this observation is the concept called nuclear

WAS DARWIN WRONG? An insight of Darwin’s theory of evolution 20th November 2013 Charles Darwin was an English naturalist who studied variation in animals and plants on a five year voyage around the world in the 19th century. He was born in 1809 and died in 1882‚ during his lifetime he managed to present his findings in his book‚ “On the Origin of Species”. Darwin’s findings caused a lot of controversy during his time and the present day‚ they were seen as conflicting with religious beliefs about

I know many people‚ if they could get almost infinite energy for almost nothing‚ they would probably do it. But Nuclear Fusion‚ unlike its cousin‚ Nuclear Fission‚ is quite difficult to achieve. Nuclear fission is the process of splitting large atoms‚ usually Uranium 235‚ to produce massive amounts of energy. The process enacted within all nuclear power plants is Nuclear Fission. Nuclear Fusion‚ on the other hand‚ is the exact opposite; Taking small atoms such as Hydrogen and pushing them together
