Paraffin wax at room temperature is solid.
Answer:
Alkenes are those organic compound which have double carbon bond
Formula of but-2-ene = C4H8
29 protons, 34 neutrons, and if there is no charge there will be 29 electrons
Explanation:
Thomson model compared the structure of the atom with a watermelon in which the red portion signifies the positive charge and the electrons which are negatively charged are embedded in this portion as seeds are embedded in the watermelon.
<u>The structure was not able to explain the stability of the atom and also the Rutherford experiment which is:</u>
Rutherford conducted an experiment in which he took a thin gold particle film on which he passes alpha- particles. He noticed that:
- Most of the alpha particles get through the film and can be detected by the detector.
- Around small portion of the alpha particle deflected at small angles.
- A very very few alpha particle (approximately 1 out of 1 million alpha particles) just retraced their path which means come back from the center.
He concluded that:
Most of space of atom is empty and in center of atom , there is solid mass which is cause of alpha particles to come back. He gave term nucleus to this solid mass.
