WebJun 21, 2015 · In short the key difference is certainty of locating electrons in the atom. Bohr's model treats electron energy levels as clearly defined orbital paths around the nucleus ( ike planets orbit the Sun). The cloud model treats the energy levels as probability clouds, i.e. regions in which electrons are likely to be found. The shapes of the clouds … WebRutherford explained the nucleus of an atom and Bohr modified that model into electrons and their energy levels. Bohr’s model consists of a small nucleus (positively charged) surrounded by negative electrons moving around the nucleus in orbits. Bohr found that an electron located away from the nucleus has more energy, and the electron which ...

WebSep 4, 2024 · Since ε o, h, and e are the constants and for a hydrogen atom, Z or atomic number is equal to 1. Hence, r n α (1/n) Total Energy of Electron in Bohr’s Stationary Orbits is given by; E n = - (me 4 /8ε o2 h 2 ) (Z 2 /n 2) or. E n = -13.6 (Z 2 /n 2) eV. The negative sign signifies that the electron is bound to the nucleus.
WebDec 29, 2024 · Draw the nucleus of an atom. A nucleus is a dense and small region that contains the number of protons and neutrons of an atom. In this step, we have to draw a small circle that consists of a number of protons and the number of neutrons of a Fluorine atom. 3. Draw the First electron shell.
