Measurement of Charge-to-Mass (e/m) Ratio for the Electron

Pasco SE-9638 Unit: The e=m tube (see Fig. 2a) is fllled with helium at a pressure of 10¡2 mm Hg, and contains an electron gun and de°ection plates. The electron beam leaves a visible trail in the tube, because some of the electrons collide with helium atoms, which are excited and then radiate visible light.

the two electron energy levels! Once an electron is in its lowest orbit, it cannot go down any further. Bohr calculated the size of the Hydrogen atom (nucleus plus one electron) by calcu-lating the distance between the nucleus and the electron in its lowest energy level. This distance is known as the Bohr radius.

Dissolved Oxygen and Carbon Dioxide

2 is electron poor with an oxidation state of IV. The electron rich oxygen of water donates an electron pair to the carbon. After proton transfer from water to an oxygen of the CO 2 unit, carbonic acid is formed. The reaction between water and dissolved carbon dioxide is reversible and rapid. Carbonic acid is in equilibrium with the bicarbonate ...
