My element is Mercury‚the atomic number is 80 and the atomic mass is 200.59.The symbol is Hg.Mercury comes from the greek name hydrargyrum which means liquid silver.The element is also known as quicksilver for its mobility. Named after the fastest-moving planet in the solar system‚ mercury has been known to humanity for ages.despite its toxic qualities‚ mercury can still be useful to us. The element conducts electricity and is used in electrical switches of thermostats and certain types of doze alarm-type

The Atomic Model has changed over time‚ as the years‚ decades‚ and centuries go by we get a better understanding of the atom and what it looks like. The Atomic Model has changed drastically based on the understanding we have on it‚ each new model has added more information to what we know about it‚ making it easier for scientists and the world to understand. The Atomic Model is a very important part of Science and Chemistry‚ it helps explain the structure and what is inside the atom‚ the particle

The proton is a subatomic particle with the symbol p or p+ and a positive electric charge of 1 elementary charge. The name proton was given to the hydrogen nucleus by Ernest Rutherford in 1920. The concept of a hydrogen-like particle as a constituent of other atoms was developed over a long period. As early as 1815‚ William Proust proposed that all atoms are composed of hydrogen atoms‚ based on a simplistic interpretation of early values of atomic weights ‚ which was disproved when more accurate

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

Considering an Alternative Fuel for Nuclear Energy: For decades‚ scientists have dreamed about turning thorium an element that their atomic number is 90 and also is less radioactive and produces less nuclear waste than uranium. Making Thorium an alternative fuel for nuclear energy. Thorium is four times more common that uranium 235 and cannot produce meltdown like the two catastrophes on Chernobyl and Fukushima. The reason that thorium cannot cause a meltdown is because his chain reaction can

Atomic energy is energy produced by atoms. The term originated in 1903 when Ernest Rutherford began to speak of the possibility ofatomic energy.[1] The term was popularized by H. G. Wells in the phrase‚ "splitting the atom"‚ devised at a time prior to the discovery of the nucleus. Atomic energy also may refer to: * Nuclear binding energy‚ the energy required to split a nucleus of an atom * Nuclear potential energy‚ the potential energy of the particles inside an atomic nucleus * Nuclear

Introduction Did you know that the first Nobel Peace Prize for Chemistry was given to Jacobus Henricus van ’t Hoff in 1901 for his discovery of the laws of chemical dynamics and osmotic pressure in solutions? Over the next 115 years it has been awarded to some of the world’s top scientists and chemists. In 1908 it was awarded to Ernest Rutherford for his investigations into the disintegration of the elements‚ and the chemistry of radioactive substances. Ernest lived a very interesting life. Author’s

Although Joseph John (J.J.) Thomson (1856 - 1940) was mainly a physicist‚ his discoveries are closely connected to the chemical community. Thomson used Crookes high vacuum cathode ray tube in his 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

Harriet Brooks was born on January 1‚ 1876 in Exeter‚ Ontario‚ Canada. She attended McGill University where she earned her bachelor’s degree in natural philosophy and mathematics in 1898. After graduating‚ Brooks began working with a research team headed by Ernest Rutherford at Mcgill (Hicks). She started working with electricity and magnetism for two years. She also was a tutor at Royal Victoria College. Brook’s interest in the sciences influenced her to get a master’s degree in physics in 1901
