In the simple Bohr model of the eighth excited state of the hydrogen atom, the electron travels in a circular orbit around a fixed proton. The radius of the orbit is 4.28 10−9 m, and the speed of the electron is 2.43 105 m/s. The mass of an electron is 9.11 10−31 kg. What is the force on the electron (in N)? (Enter the magnitude.) See answer

As n increases, the radius of the orbit increases; the electron is farther from the proton, which results in a less stable arrangement with higher potential energy (Figure 2.10). A hydrogen atom with an electron in an orbit with n > 1 is therefore in an excited state.

The discovery of nuclear fission by German chemists Otto Hahn and Fritz Strassmann in 1938, and its theoretical explanation by Lise Meitner and Otto Frisch, made the development of an atomic bomb a theoretical possibility.

J. Robert Oppenheimer (/ ˈ ɒ p ə n ˌ h aɪ m ər /; April 22, 1904 – February 18, 1967) was an American theoretical physicist.He was the director of the Los Alamos Laboratory during World War II, and is often credited as the "father of the atomic bomb" for his role in the Manhattan Project, the research and development undertaking that created the first nuclear weapons.

subatomic particle, or elementary particle, Any of various self-contained units of matter or energy. Discovery of the electron in 1897 and of the atomic nucleus in 1911 established that the atom is actually a composite of a cloud of electrons surrounding a tiny but heavy core. By the early 1930s it was found that the nucleus is composed of even.

If an atom contains one electron and one proton, will it carry any charge or not? asked Mar 26, 2020 in Chemistry by Sandhya01 ( 59.3k points) structure of the atom

So, the electron distribution in a carbon atom will be : `underset("2, 4")("K L")` (ii) The atomic number of sodium is 11, so a normal atom of sodium has 11 electrons in it. Out of these 11 electrons, the first 2 electrons will go to K shell, the next 8 electrons will go to L shell and the remaining 1 electron will go to M shell.

Solution. An electron is a negatively charged particle, whereas a proton is a positively charged particle. The magnitude of their charges is equal. Therefore, an atom containing one electron and one proton will not carry any charge. Thus, it will be a neutral atom. Suggest Corrections.

Exercise 2.6.3 Summary Key Equations Glossary Learning Objectives Describe the locations, charges, and masses of the three main subatomic particles. Determine the number of protons and electrons in an atom. Write and interpret symbols that depict the atomic number, mass number, and charge of an atom or ion.

You'll need to gather basic information about the elements to find the number of protons, neutrons, and electrons. Fortunately, all you need is a periodic table . For any atom, what you need to remember is: Number of Protons = Atomic Number of the Element. Number of Electrons = Number of Protons.
