Answer : Broadly solids are divided into three categories;
i) Crystalline solids have a regular definite structure, in which the particles pack in a repeating pattern from one edge of the solid to the other.
ii) Amorphous solids have a random structure, with little unorganized pattern long-range order.
iii) Polycrystalline solids are those where an aggregate which consists of a large number of small crystals or grains in which the structure is regular, but the crystals or grains are found to be arranged in a random fashion.
Also solids can be divided into 3 more categories according to their bonds;
i) Covalent solids, like diamond, which forms crystals that can be viewed as a single giant molecule made up of an almost endless number of covalent bonds.
ii) Ionic solids are basically salts, such as NaCl, in which the molecules are held together by the strong force of attraction between ions of opposite charge.
iii) Metallic solids are found in metals which have the force of attraction between atoms of metals, such as copper and aluminum, or alloys, such as brass and bronze, are metallic bonds.

Explanation:
Answer:
Protons are positively charged. The mass is slightly lower than a neutron.The location of a proton is nucleus. The the role of a proton is to help bind the nucleus together.
Explanation:
The correct answer is - T (True).
The goal and purpose of the environmental engineers is to minimize the impact of the land that is being developed on the environment itself. This is due to the efforts being made that the environment is kept as it is as much as possible, because any damage on it has bad consequences for everyone and everything. So this type of engineers are trying to find the perfect balance between the development of the land for human usage and also to manage to preserve as much as possible the environment and to minimize any damage on it.
The relationship between hypotheses, laws and theories is that a law is used to explain hypothesis and theories.
<h3>What is a law, a theory and hypothesis?</h3>
A hypothesis is a tentative conjecture explaining an observation, phenomenon or scientific problem that can be tested by further investigation or experimentation.
A theory is a coherent statement or set of ideas that explains observed facts or phenomena and correctly predicts new facts or phenomena not previously observed.
A law is a statement whose sequence or relationship of phenomena is invariable under certain conditions.
This suggests that a law can be used to explain a theory and hypothesis.
