<h2>Bombarded α-Particles on a thin Sheet of Gold
</h2>
Explanation:
- Rutherford Atomic Model is also known as " The plum pudding model"
- Rutherford’s in his experiment bombarded α-particles which are of high energy on a thin sheet of gold nearly 100 nm of thickness and observed the trajectory path of these particles after interacting with the foil of gold.
- He placed a fluorescent screen of zinc sulfide around the thin gold foil to study the trajectory path of the α-particles and its deflection.
- Most of the α-particles passed through the gold foil were not deflected as most of the internal space of the atom was empty.
- The result was that the positive charge of the atom occupies very little space.
Answer:
Sharing or covalent bonding is taking place.
Explanation:
The valence electron will be shared by both the atoms so that means that the election will move around both of the atoms.
The variables to be examined in relation to carbon dioxide use are the amount of light exposure and amount of dissolved CO2. Phenol red is yellow/orange under acidic conditions, that is when the pH of the solution is less than 7 (e.g. pH = 6). This occurs when the concentration of CO2 is high.
The substance (water) used to clean the beaker could effect the outcome of the experiment.
