well, ive found, stuff like sponges, wood, leaves and grass. not sure about the toothpaste though!!!!!!!!!!!!
Atomic theory is applicable to all the matter in the universe.

A particle in an atom is a tiny piece of anything. It is a function word that can be used in English to form phrasal verbs. It is also a body having finite mass and internal structure but negligible dimensions.
1. Particle Model: Invented by Sir Isaac Newton. He devised a simple particle model to explain the properties of light. He preferred to consider light as a stream of small particles or corpuscles. These particles were emitted in all directions by a light source, travelled in straight lines and carried energy. For example, in this model, the reflection of light was considered as being similar to a tennis ball rebounding from a wall with equal angles of incidence and reflection.2. Wave Model: In 1690, the Dutch physicist Christiaan Huygens published his Treatise on Light which developed the idea that light, like sound, travelled as a wave through a medium called the ether.Hope this helps :)
If you think of light as made up of small, elastic particles, then when they hit a hard surface, they will bounce off and travel in another direction. This is analogous to a basketball bouncing off a floor. However, the particle nature of light has been disproven. A more accurate description lies in the wave or particle-wave duality nature of light.
It can mean: 1. the substance loses oxygen 2. the substance gains hydrogen 3. the substance gains electrons 4. the oxidation state of a substance after a reaction decreased
They are: 1. Conceptual-such as our mental image of the DNA spiral, helps frame research questions and make general predictions 2. Numerical-uses math or statistics to describe the image and make quantitative predictions about it 3. Physical-physically represents the object and it's apprearance
