What is the meaning of the term amorphous element? Give an example. Describe an element. What is meant by the term ion? What does the term synthesis mean in chemistry? What characteristic distinguishes element from compound? What is the meaning of the term "proton" as used in chemistry?
Why is lattice energy important in forming ionic bonds? What is the net effect of forming an ionic bond? What is the difference between a covalent and an ionic bond? What are three differences between the bonding in ionic and molecular substances? Explain the meaning of electron transfer and ...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, s...
Another form, amorphous silicon, is used to make the glass that covers solar panels, but it has also found its own use in thin-film solar cells. This type of silicon has an irregular or amorphous crystal structure, which means it doesn't really have any repeating or lattice-like ...
However, if you were to look at a grain of salt, made up purely of NaCl, you wouldn’t consider it a molecule, as it is in fact a huge lattice network of individual sodium chloride compound particles, without a clear number of atomic nuclei. The same thing is true if you look at ...

the elementary excitation. The vibration is in the lattice, and the phonon is an excitation in which energy is not lost to the environment (a dissipation less excitation). A phonon can be pictured as an atom vibrating in a lattice. It is the quantum of energy and excitation in a crystal...
Explain the term lattice type in detail. Define the terms germicide and bacteriostat. What are the two characteristic properties of matter? Briefly define polarizability. What is the meaning and purpose of ionization energy? Give an example to your explanation. What does the term "resonance" mean...
