Main Points
- Gravity is an attractive force that acts between objects possessing mass.
- It plays a crucial role in maintaining the orbits of Earth and other planets around the sun.
- The intensity of gravity is determined by the mass of the objects and the separation between them.
This process is primarily a physical reaction rather than a chemical one. The americium present in the smoke detector releases high-velocity alpha particles (helium nuclei). These particles collide with air molecules, dislodging electrons and creating ions. For instance, the reaction can be represented as:
O2 + He(+2) --> O2(+1) + e(-1) + He(+2)
(The charge is denoted within the parentheses.)
