Thomsons model( commonly the plum pudding model) - can also be described by a watermelon cut horizontally. The red of the water melon is a positively charged cloud with the seeds representing the negatively charged electrons sprinkled through out the positive cloud.
Rutherford had a model with a dense positively charged nucleus at the center. This nucleus was encircled by negatively charged atoms.
Answer: <span>b. positive charge concentrated at the center of the atom</span>
Answer:
Explanation:
One of the major differences between nuclear reactions and chemical reactions is that nuclear reactions involve larger amount of energy than chemical energy. <u>This is because the force between the protons and neutrons in the nucleus of an atom is much higher than the force of attraction between electrons and the positively charged nucleus, hence nuclear reactions involves/requires a larger amount of energy (because it's reactions involve the nucleus) than chemical reactions (because it's reactions involve the electrons)</u>.
Thus, during nuclear fusion, two light nuclei are bombarded against one another to produce a larger/heavier nuclei with the release of large amount of energy (because the forces between the protons and neutrons are much higher) unlike when two atoms/molecules are chemically combined together to form a new molecule with the rearrangement of electrons in the valence shells of the participating molecules.
Explanation:
1. Height Relatives to reference point, Mass, and strength of the gravitational field it's in
2. Distance in the magnetic field
Answer:
1. A burning streak of light, called a Meteor.
2.The rocky bodies that survives the fall to the planet’s surface are Meteorites.
Explanation:
Let us see the difference between them.
- Asteroids: They are the remnants of a broken planet orbiting the sun in between Mars and Saturn. They are small rocky bodies from a tennis ball size to larger ones weighing a few tones.
- Meteoroids: They are the small rocky objects of pebble size formed due to the collision of asteroids.
-
Meteors: These are pebble size objects that enter Earth's atmosphere and burns off by forming streaks of light.
- Meteorites: These are rocky objects bigger than meteors than don't burn out completely and fall on the earth's surface.
-
Comets: These are objects mainly made of dust and ice that orbit the sun in a highly elliptical orbit. This composition makes a long tail when approaching the sun.
