Activated complex
1. Discuss recent developments in the structure of the atom. What new particles have been identified?
molecular structure
two protons, two neutrons.
yes
There are three states of matter, solid, liquid and gas. The state of matter wherein particles are fixed in a rigid structure is solid.
The Nucleus.

Because they are particles, and they are part of the atomic structure.

Soil Structure.
they described the structure of DNA
In a liquid, the particles are free to move around; in a solid, they have a fixed position. In a solid, the particles may have a regular structure (i.e., a crystal), or the structure may be irregular.
The size of rock particles are important to soil structure because the larger particles of sand allow rainwater to drain quickly through the soil, while the smaller particles of clay prevent rapid drainage.
