If the impurity is of type "n" - an element (the impurity) that has 5 electrons in its outer shell - conduction will be mainly via electrons. If the impurity is of type "p" - the atoms of the impurity has 3 electrons in its outer shell - the conduction will be mainly via holes.

How would your results in the calorimetry lab be affected by the presence of impurities?
The presence of impurities in the calorimetry lab can affect the accuracy of your results. Impurities can alter the heat transfer process, leading to incorrect measurements of energy changes. This can result in inaccurate calculations of heat capacity and other important values in the experiment.
The color of fluorite changes due to .?
The color of fluorite changes due to the presence of impurities in its crystal structure. Different impurities can interact with light in various ways, influencing the color of the fluorite. This phenomenon is known as "color zoning" and can result in a wide range of colors in fluorite crystals.
What physical properties may change resistivity?
Resistivity can be affected by several physical properties, including temperature, impurities, and structural defects within a material. As temperature increases, the resistivity of conductors typically rises due to increased atomic vibrations that hinder electron flow. In contrast, semiconductors may exhibit decreased resistivity with rising temperature due to enhanced carrier mobility. Additionally, the presence of impurities or defects can disrupt the lattice structure, leading to changes in resistivity by altering the number of charge carriers or scattering mechanisms.
The color of fluorite changes due to what?
The color of fluorite changes due to impurities in its chemical composition. Trace amounts of different elements such as iron, yttrium, or europium can cause fluorite to exhibit a range of colors, from purple and blue to yellow and green. The presence of these impurities alters the way the crystal absorbs and reflects light, resulting in varied coloration.
What is semicoductor?
A semiconductor is a material that has electrical conductivity between that of a conductor and an insulator. Typically composed of elements like silicon or germanium, semiconductors can conduct electricity under certain conditions, such as the presence of impurities or changes in temperature. This unique property makes them essential for modern electronic devices, including transistors, diodes, and integrated circuits. Their ability to control electrical current is fundamental to the functioning of computers, smartphones, and other technologies.
Boiling point of water is 100 degree celsius but why it boils at 130?
Water boils at 100 degrees Celsius at sea level. If water is boiling at 130 degrees Celsius, it might be due to the presence of impurities or changes in atmospheric pressure, which can affect the boiling point of water.
Why does the color of flourite change?
The color of fluorite changes due to the presence of impurities or trace elements in its structure. These impurities can alter the crystal lattice, causing it to absorb different wavelengths of light and display a range of colors. Environmental factors such as heat and radiation can also influence the color change in fluorite.
How are bubbles formed and what factors contribute to their creation?
Bubbles are formed when a gas is trapped within a liquid or solid material. Factors that contribute to their creation include surface tension, pressure changes, and the presence of impurities in the liquid.
How do bubbles form and what factors contribute to their creation?
Bubbles form when a gas is trapped within a liquid or solid material. Factors that contribute to their creation include surface tension, pressure changes, and the presence of impurities or surfactants.
How do rocks change colors?
by weathering ************ Igneous rock is initially formed when lava cools down. After which weathering would begin.
Why can the refractive index of water change?
The refractive index of water can change with factors like temperature, pressure, and the presence of impurities or contaminants. Changes in these factors can alter the density and molecular structure of water, affecting how light travels through it and thus causing variations in its refractive index.
Do impurities raise or lower the refractive index of a substance?
Impurities can cause a significant change in the reflective index of a liquid. Impurities totally affect the results of the experiment. It changes the reflective index and affect the concentration of the solution.
