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

This time had both positive and negative effects‚ as even though the Industrial Revolution greatly increased productivity and made many advancement in technology‚ with more and more people could enjoy cheaper and more varieties of consumer goods‚ the negative effects were equally as enormous.

the centre of the atom. On the periodic table‚ going across from left to right‚ the atom’s relative size decreases. However‚ going down the group‚ the atomic radius increases in size. From left to right there is an increase of positive charges in the neutron and the electrons. Due to the increase of the number of positive charges‚ the electron’s attractive force becomes stronger‚ thus (the electrons) being drawn close to the nucleus. The stronger the attractions causes the electrons move closer to the

financially accessible for many people. Funding also creates the negative effect of stress from long term debt that many students face in post secondary education. As government funding fails‚ it also creates the downfall of high quality faculties. Post Secondary education systems encourage people to pursue higher education to build future economic success but in doing so funds should also be affordable. Since funds are expensive‚ negative effects become more prevalent throughout post secondary education

Separation of Amino Acids by Cation Exchange Chromatography Introduction and Purpose: Amino acids are small biomolecules that have a carboxylic acid backbone in common‚ as well as an amino group attached to a saturated carbon. There are many amino acids‚ but there are 20 most commonly know amino acids. Amino acids are the fundamenta building blocks of other biomolecules like proteins and ezymes (Davidson‚ 2015). This experiment examined a mixture of 3 amino acids. The purpose of this experiment

Energy and Electron Affinity Ionization Energy is removing an electron Electron Affinity is adding an electron Ionization Energy • Energy required to remove an electron from a ground state atom Ionization Energy of Noble Gases • Noble gases have full orbitals‚ so it is difficult to remove an electron from them. But‚ it does become easier the further away the electrons get from the nucleus. Ionization Energy of Alkali Metals • Alkali Metals only have one valence electron‚ so it does

Charge Negotiation Charge negotiations during a criminal trial are between the accused person and prosecutor. It is when the accused agrees to admit to a crime (sometimes a lesser crime that the one set out in the original charge eg. Admitting to manslaughter rather than murder). A plea of guilty will generally attract a discounted sentence and avoids spending taxpayer’s money. Negotiations are conducted in accordance with the Prosecution Guidelines of the Office of the Director of Public Prosecutions
