Where are x-rays made? Answer in the electron shell structure of an atom What is Bremsstrahlung radiation? Answer energetic electrons pass very near the nucleus of an atom. The strong forces of th positive charged atom causes the negatively charged electron to decelerate; the path of the electron is changed, and some of the kinetic energy of the electron is lost, and converted into x-rays what is characteristic x-ray radiation? Answer following the ionization of an atom that leaves an inne...

The earliest atomic theory based on an arrangement similar to the solar system is attributed to (Ans- Rutherford. The three fundamental particles of the atom are the (Ans- neutron, electron, and proton. The atomic nucleus contains (Ans- protons and neutrons. The component of the nucleus that has a positive charge and mass is the (Ans- proton. The electron shell closest to the nucleus is lettered (Ans- "K". Which of the following is not part of the electromagnetic spectru...

ATOMS - Answer FUNDAMENTAL SUBMICROSCOPIC UNIT OF ALL MASS. SIZE OF THE ATOM AND ITS WEIGHT HAVE INTERESTED SCIENTISTS FOR A LONG PERIOD. SUBSEQUENTLY, EXPERIMENTS WERE DEVISED TO DETERMINE THE SIZE AND WEIGHT OF THE VARIOUS ATOMS. THE LIGHTEST OF ALL ATOMS IS HYDROGEN. PROTON - Answer A SUBATOMIC PARTICLE HAVING A POSITVIE CHARGE IDENTICAL IN MAGNITUDE TO THE NEGATIVE CHARGE OF AN ELECTRON AND, TOGETHER WITH THE NEUTRON, A COMPONENT OF ALL ATOMIC NUCLEI. THE PROTON FORMS, BY ITSLEF, THE NUCL...

Why are larger atoms more unstable? - Protons repel each other more and more as the atom gets larger. Three types of nuclear radiation - alpha radiation, beta radiation gamma radiation alpha decay equation - 4/2 He subtract 4 from mass number subtract 2 from atomic number beta decay equation - 0/-1 e mass number *remains the same* add 1 to the atomic number gamma decay symbol - 0/0 y both mass and atomic number *remain the same* nuclear fusion - a nuclear reaction in which atomic nu...
