The Standard Model Of Particle Physics

The Standard Model of particle physics is a theory concerning the electromagnetic, weak and strong forces, as well as classifying all the subatomic particles known. It was developed as a collaborative effort of scientists around the world during the latter half of the 20th century. Because of its success in explaining wide variety of experimental results, the Standard Model is often referred to as a "theory of almost everything". Although the Standard Model is quite consistent, it does not address some profound questions about the nature of the universe and it does leave some phenomena unexplained. One of these phenomena that the Standard Model doesn't explain is gravity. (CERN, 2015)

12. Briefly define the following: Matter is anything that takes up space. Element is any substance that can’t be broken down into substances with different properties. Atom is the smallest part of an element that displays the properties of the element.

     String theory is defined by Merriam-Webster as, “A physical theory in which one-dimensional loops travel through space and also merge and lyse as time elapses. This is in contrast to ordinary quantum field theory, which predicts point particles that emit and absorb each other. String theory is a candidate for a Theory of Everything.” String theory would solve the long fight between Einstein’s theory of relativity and Quantum Physics.

What is matter? Matter is the substance of which any physical object is composed of. Matter takes up space and has mass. Matter can actually undergo lots of changes either chemically or physically. During chemical changes, matter’s chemical composition changes. Bonds between atoms are broken and created to form new molecules! For an example, a rusting iron nail. When a iron nail is exposed to oxygen it transforms into rust, this ability to react is the chemical property/change. During physical changes, matter’s composition does not change. Something in the matter might seem or look different, but the atoms are still link up the same.

Quantum Mechanics is the science of subatomic particles and their behavior patterns that are observed in nature. As the foundation of scientific knowledge approached the start of the twentieth century, problems began to arise over the fact that classic physical ideas were not capable of explaining the observed behavior of subatomic particles. In 1913, the Danish physicist Neils Bohr, proposed a successful quantum model of the atom that began the process of a more defined understanding of its subatomic particles. It was accepted in the early part of the twentieth century that light traveled as both waves and particles. The reason light appears to act as a wave and particle is because we are noticing the

We can use the small numbers to give information about the particles in the nucleus.

To discover what the universe is made of and how it works is the challenge of particle

It starts with subatomic particles, such as protons and electrons, produce electrical fields. These relating electrical fields are composed primarily of electrons,

What is an atom? An atom is the basic building block of everything. An atom is made of electrons protons and neutrons and the number of protons determines the element. Back in the 1800’s this whole idea was unknown. In the 1800’s steam was starting to power everything. It became important to know how steam works, so you can learn to use it more effectively. It was this idea that drove Dalton to research the atom.

Around 2,500 years ago, Democritus and his partner Leucippus were the first ones to develop the atomic theory in written history. Their theory proposed that every kind of matter was made up of tiny particles, which were named atomos, which means that it is indivisible. This meant that Democritus and Leucippus thought there were little particles of everything, but, the next breakthrough in atomic theory wasn’t made until the early 1800s with a french chemist by the name of Antoine Lavoisier, he was the one who came up with the idea of the law of the conservation of mass, which states that matter stays the same even when it changes shape or form. Then, James Dalton said that all matter was made up of atoms, which were indivisible, and unbreakable.

What is the atomic structure you may ask? Well, it’s the law stating the structure of an atom. It is composed of a positively charged nucleus containing a certain amount of protons (positive), neutrons (neutral charge), and electrons (negative). The amount of each subatomic particle (proton, neutron, and electron) all depend on what the element is. Now although this statement may seem fairly simple it was most definitely not. People have been studying the atomic structure for more than 300+ years and are still studying it. So after reading this you may wonder who even made this atomic structure up. After hundreds of years of research there is not any one individual who made the structure up but roughly

Matter, possesses mass, but is distinct from energy. It is the basis of everything on earth and in space. Therefore, it is the basis of me. An atom is the smallest unit of matter, which forms all of the elements I am composed of. Roughly 96% of my body is formed from carbon, hydrogen, nitrogen, and

What is an atom? An atom is a small particle that makes up most types of matter(OI). The atom was first discovered by Democritus in about 300 B.C.(Doc 1). He believed that bits of matter were too small to see and could not be divided. As a result he named it the atom, which means cannot be divided in Greek. This was the first step to understanding matter. The next person to study atoms, 2,000 years later, was a French chemist by the name of Antoine Lavoisier(OI). From his experiments,

When looking at all the different theories they all have something common. They are just a theory. What I mean by this is they are a thought or suggestion of how things happen or work. The reality is some theories are good and plausible. Others on the other hand not so much. All of Chapter 4 is all about the different theories. So this paper is a summary of some of those theories.

An Atom is the the basic building block of all matter. Atoms are made up of Particles, called: Protons, neutrons and Electrons. Protons carry a positive charge, the neutron carry 's a neutral charge and the electron carry’s a negative charge. The Atom has two main parts the Nucleus and the Electron Shell. The Nucleus contains the Protons and Neutrons. The electron Shell Contains the The electrons.
