1. What causes the lines to be produced in this way? The different electron energy levels caused in hydrogen cause these lines in the spectrum to be produced in this way because the wavelengths that are released when the electron move back to the ground state is specific and it varies accordingly. 2. Into which energy level are electrons dropping into to make these visible lines? The electrons are dropping back to the ground state which is the bottom most energy level to makes these visible lines

common observed behavior – similar charges repel and opposite charges attract. The experiment went expected as there were no unusual observations recorded. In the first part‚ it was observed that when the plastic rod was rubbed it attracted the tissue bits. The explanation with this is‚ when the plastic rod was rubbed‚ it became electrically charged. Conduction happens when the tissue paper was rubbed into the plastic rod. The tissue paper transferred electrons to the plastic rod. The plastic is

purpose of this lab is to examine the motion of an electron‚ when it encounters a constant magnetic and electric field. We will also observe when the electric field and magnetic field will cancel each other out. This will lead to the electron having no net force acting upon it. By adjusting the values for the magnetic and electric fields‚ we will be able to check the different paths the electron follows. From this data we will be able to calculate the charge-to-mass ratio. Then‚ using the accepted value

tourism in India In recent years tourism in India has shot up at lightening speed. India has succeeded in becoming the most preferred place amongst domestic and overseas traveler. Tourism exposes the international traveler to India’s diverse culture. According to some official estimates Indian tourism has surpassed global tourism as far as penetration of foreign tourists and revenue is concerned. As far as internal reasons are concerned‚ India tourism has progressed due to the rate of growth of Indian

Negative Effects Technology Has on Teens Olivia Urzi June 6‚ 2014 Throughout the years technology has effect people around the world‚ teens were mostly effected by technology. Technology had not only made a positive effect on teens. But‚ technology has made a negative effect on teens‚ by keeping them from going out‚ exploring‚ and interacting with people. The negative effects electronics had on teens vary. From the way teens think of themselves‚ to the way they act‚ and how they interact

ELECTRICAL SUBSTATION A substation is a part of an electrical generation‚transmission and distribution system. Substations transform voltage from high to low‚ or the reverse‚ or perform any of several other important functions. Electric power may flow through several substations between generating plant and consumer‚ and its voltage may change in several steps. Substations may be owned and operated by a transmission or generation electrical utility‚ or may be owned by a large industrial or commercial

The Manhattan Project World War II started on September 1 1939‚ when Germany attacked Poland. By 1941‚ the Germans were ahead in the race for the atomic bomb. They had a heavy-water plant‚ high-grade uranium compounds‚ capable scientists and engineers‚ and the greatest chemical engineering industry in the world. Even before its entry into the war‚ the United States had become very concerned with the nuclear threat of the Axis powers. On October 11‚ 1939‚ President Franklin D. Roosevelt received

Over time many theories have been developed into the structure of the atom and what the world around us is composed of. Many scientists and philosophers have dedicated their life works into trying to understand how atoms work and what they are made up of‚ although not all theories have been accepted they have all come together to form what we know today. It all started from a Greek scientist called Democritus‚ who developed the idea that everything is made up of smaller things‚ which he named atomos

Pineda‚ Carlitos Miguel Ponce M. January 9‚ 2013 AIT2A Natural Science 12 ATOM DEVELOPMENT WITH SCIENTISTS INVOLVED 400 B.C. - Democritus’ atomic theory posited that all matter is made up small indestructible units he called atoms. Democritus expanded the idea to state that matter was composed of small particles called "atoms" that could be divided no further. These atoms were all composed of the same primary matter with the only differences between them being their size‚ shape

Chapter 9 – Electrons in Atoms and the Periodic Table True/False Questions 1) When the elements are arranged in order of increasing number of protons‚ certain sets of properties recur periodically. 5) A particle of light is called a packet. 9) Ultraviolet light produces suntans and sunburns. 13) Electrons behave like particles and we can describe their exact paths. 17) The ground state is when an electron in an atom is excited into the lowest possible vacant orbital. 21) Bromine has 17 valence electrons
