Biography: The Dignified Professor‚ Richard Feynman a notable XXXXXX. He was born in New York City on May 11‚ 1918. His education journey includes studies of Physics at well – distinguished universities‚ Massachusetts Institute of Technology‚ and Princeton University. As a doctoral graduate‚ he was privileged to work on atomic bomb projects at Princeton and a secret government location in Los Alamos‚ New Mexico. As a young adult‚ his leadership abilities were evident positioning him to manage a

Honor- someone who did something to earn high respect. Honor to me is someone who put others first before thinking of themselves who is also respected. Albert Einstein is honored for the laws of nature he has discovered‚ which truly change the way we look at science. Einstein created one of the most famous known equations which is known as E = mc2. The equation says that mass (the m) can be converted to energy (and the E). A little mass can make a lot of energy‚ because mass is multiplied by c2

The Atomic and Nuclear Structure of an Atom The atom has three main components the protons‚ neutrons‚ and electrons. The protons and neutrons make up the nucleus‚ while the electrons are found outside the atom’s nucleus. Each component of an atom has a charge to it. The protons have a positive charge. The electrons have a negative charge‚ and the neutrons have a neutral charge. The atoms also have a charge. For example hydrogen can be negative‚ positive or neutral. These are called

derived from the distances between two nuclei when the two atoms are joined in a chemical bond. The radius varies with the location of an atom on the atomic chart‚ the type of chemical bond‚ the number of neighbouring atoms (coordination number) and a quantum mechanical property known as spin. On the periodic table of the elements‚ atom size tends to increase when moving down columns‚ but decrease when moving across rows (left to right). When subjected to external fields‚ like an electrical field‚ the

What is the particle theory? The particle theory says that that matter consists of many small particles with spaces in between. The particles are constantly moving‚ the higher it’s temperature‚ the faster they move. All the particles are attracted to each other. The particles move faster and move further apart when heated‚ and the reverse when cooled. Each substance has unique particles that are different from the particles of other substances. Particle theory helps to explain the behaviour of
