Science Holiday Homework Aldo 10D The Rutherford’s Experiment and the Geiger Marsden experiment were both the same experiment‚ where Rutherford being the mentor of Geiger and Marsden in the investigation of the experiment at the University of Manchester in 1909. The experiment was so important because it changes our view and understanding upon the structure of the atom. Before Rutherford‚ there was a man named Joseph John Thomson who proposed the structure of the atom. He stated that the electrons

Section A: Analyse the strategic market environment of Saga Holidays Introduction Saga Holidays was a family-run business which started from year 1948. This business had steadily grown until nowadays. As a result‚ it has recognised reputation as a travel organiser that concentrated serving the older target market only. However‚ the chairman of the Saga Holidays had decided to retire in October 2004. Thus‚ he had sold the organisation to the Charterhouse with an incredible amount of £1.35bn

conductor than copper‚ which has four orbits. Silver is often used as a coating on electrical conductors in order to keep the resistance as low as possible. Now‚ let’s look at an atom of carbon (Figure 7). The nucleus of the carbon atom contains six protons and six neutrons. Six electrons orbit the nucleus. Now‚ look more closely at the electrons.

Matthew Rose Mr. Schwartz Chemistry 8 March 2011 Ernest Rutherford Ernest Rutherford was one of the most famous physicists of the early 20th century. He won the Nobel Prize in chemistry in 1908 for his work on atomic emissions and his contributions that led to the discovery of atomic fission. Ernest Rutherford was born in Nelson‚ New Zealand on August 30‚ 1871. His father was James Rutherford and his Mother was Martha Thompson. His father was a wheelwright‚ a person who builds and repairs

of protons. Because the plot shows only the stable isotopes‚ this graph is often called the Nuclear Belt of Stability. The plot indicates that lighter nuclides (isotopes) are most stable when the neutron/proton ratio is 1/1. This is the case with any nucleus that has up to 20 protons. As the atomic number increases beyond 20‚ a different trend becomes apparent. In this range‚ it appears that a stable nucleus is able to accommodate more neutrons. Stable isotopes have a higher neutron to proton ratio

The conjugate acid of water is the hydrated proton written as H3O+ Amphiprotic solvent – solvent that can act either as an acid or as a base‚ a classic example is water. The weakest acid forms the strongest conjugate base The tendency of a solvent to accept or donate protons determines the strength of a solute acid or base dissolved

Analytical techniques are vital in everyday science and so NMR procedure is an absolute essential to deduce compounds and chemical structures; this assignment requires the identification of two samples using an NMR software program. Background NMR spectroscopy is a well established method for structure determination of various organic molecules ranging from small molecules all the

Atomic nuclei consist of protons and neutrons‚ which have a positive or negative charge. Electric forces are repulsive between similar charges‚ so there must be a force much stronger than electromagnetism keeping them together. This force is called the Strong Nuclear Force‚ and it is about a hundred times stronger than the electromagnetic force. Its strength allows it to hold a nucleus together‚ despite the desire of the electromagnetic force to thrust it apart. Despite its relative strength‚ the
