Introduction Atoms‚ molecules‚ compounds and mixtures‚ although they may not seem it‚ are different. Atoms make up all of the above and elements. They are made an equal amount of protons and electrons. Molecules are made when two or more atoms connect chemically. Like molecules‚ compounds are made when two or more atoms connect chemically. Unlike molecules‚ the atoms need to be two or more different elements. Mixtures are made of two or more compounds or elements. Mixtures can look completely the

of the electron transport chain in cellular respiration. In your explanation‚ discuss and identify key molecules involved in this process and explain their relationship which each other in terms of how they contribute to the main cellular purpose of this process. Electron transport chain plays a key role of in the production of oxygen in cellular respiration. ETC uses many enzymes located on the inner mitochondrial membrane during the production of oxygen. The source of these electrons are NADH

discovery of electrons. He found the green beam produced by the cathode ray tube was a completely negatively charged material. Experimenting with different electrically charged plates and magnets in the cathode ray tube and observing the deflection of the rays he had enough evidence to say that particles smaller than atoms existed. By doing this experiment multiple times he compiled enough data to conclude that the mass of one of these particles‚ which he called an electron‚ was lighter than an atom of hydrogen

relationship between the core charge and valence electrons. When moving across a period each element will have the same number of shells‚ but each of their core charges are going to be different. The core charges become higher the farther across the period you move. An increase of core charge‚ means a decrease in shells making it harder to pull electrons away because they are closer to the nucleus‚ which causes for there to be a great attraction between the nucleus and electrons. When looking at moving

C 1: Fundamental ideas: C 1.1. Atoms‚ elements and compounds: * All substances are made up of atoms. * Elements contain only one atom. * Compounds contain more than one atom. * An atom has a tiny nucleus in its centre‚ surrounded by electrons. C 1.2. Atomic structure: * Atoms are made up of protons‚ neutrons and electrons. * Protons and electrons have equal and opposite electrical charges. Protons are positively charged‚ and electrons are negatively charged. * Neutrons

BOHR’S MODEL OF ATOM MADE BY:-GROUP-1{CHEMISTRY} About The Scientist……. HE was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory‚ for which he received the Nobel Prize in Physics in 1922. Bohr was also a philosopher and a promoter of scientific research. He was born in Copenhagen on 7 October 1885. He wrote many books like the theory of spectra and atomic constitution‚ atomic theory and the description of nature. NEILS BOHR

Now think about how much you depend upon it. I would even have to assume that you use it for every thing from work ‚ school ‚ and entertainment.

Enclosure C1 is written by Rune Engelbrecht Larsen‚ enclosure C2 is written by Ida Auken and Astrid Krag (SF) and enclosure C3 is written by Bo Lidegaard. What all the three enclosures has in common is‚ that they all have immigration policy in focus. According to the enclosures‚ it is therefore the immigration policy that determines the content of the value policy in

Electron Transport Chain The first step in the electron transport chain process is for the NADH2 produced during glycolysis‚ the intermediate step‚ and the citric acid cycle to be attracted to Complex I (FMN ·FeS)due to its high affinity for NADH2. This attraction pulls NADH2 to Complex I (NAD dehydrogenase) and the two electrons from H2 are pulled off by the FeS (ferrous sulfate) leaving two H+ ions and NAD+. These molecules repel each other and this results in the NAD+ being recycled
