Pre-Ap Physical Science: The Importance Of Electrons

507 Words3 Pages

Dylan Clayton Mrs. Beckwith Pre-Ap Physical Science 9 7 December 2015 The Importance of Electrons Electrons are the negatively charged subatomic particles that revolve the center, nucleus, of an atom. They are arranged in different energy levels and they orbit around the nucleus like the Earth revolves around the Sun. Electrons are important in atoms, compounds, and chemical bonds involved in chemical reactions. These subatomic particles have importanance to the organization of elements into periods & groups, characteristics of elements in the same periods & groups, and the formation of compounds based on periodic table placement. The organization of periods and groups consist of the number of valence electrons. Periods are the rows

    Task 1 (P1) The periodic table is laid out into groups and periods. They are also put into different blocks S-Block, D-Block, P-block and F-Block due to their energy levels. They are organised by their energy levels and chemicals properties. As the elements go along the periods in the periodic table the electronegativity increases but as the elements go down the groups the electronegativity decreases.

    Many people do not realize that chemistry is a part of our day to day lives. One specific thing we see on a daily basis is the colors and paint people use in paintings, on buildings, and any other place paint could be. When this paint is developed, the people who make it have to decide exactly what the compound should be made up of. This is an important thing to consider when making these paints because as discussed in Chemistry 101 lab, compounds are different things that develop one item, in this case it is paint. They have to make sure that the paint is homogenous because if it was heterogeneous when being applied, the paint would not go on well.

  • The Importance Of Photoelectric Interactions

    919 Words  | 4 Pages

    Photoelectric interaction is one of the main interactions in producing x-rays. This occurs when an inner shell electron is knocked out leaving a hole that needs to be filled. It will be filled by an outer shell electron which will be filled by an auger electron eventually. Photoelectric interaction doesn’t have as much scatter compared to the other interactions. This is due to the photons being almost completely absorbed by the patient as the photons pass through the body to hit the image receptor.

  • Why Do Electrons In An Atom Occupy Different Energy Levels

    The electrons in an atom occupy different energy levels. When all of the electrons are at the lowest possible energy level they are said to be in the ground state. Sometimes they can be promoted to a higher-energy electron shell. First, the electron can absorb a photon of just the right amount of energy to move it from one quantum shell to another.

    What is electromagnetism? Merriam-Webster states that “electromagnetism is magnetism developed by a current of electricity.” An alternative definition suggests that electromagnetism is a fundamental physical force that is responsible for interactions between charged particles which occur because of their charge. To fully understand how electromagnetism affects us, it is important to understand the basic foundation of electromagnetism. The field of electromagnetism was only six years old when Henry began teaching at the Albany Academy in New York.
