What is the atomic number of a nucleus that carries a charge 1.44 x 10 18 and a mass of 3.173 x 10 26?
The atomic number of an element corresponds to the number of protons in its nucleus, which also equals the charge of the nucleus in coulombs divided by the charge of a single proton (approximately (1.6 \times 10^{-19}) coulombs). Given a charge of (1.44 \times 10^{18}) coulombs, the atomic number (Z) can be calculated as (Z = \frac{1.44 \times 10^{18}}{1.6 \times 10^{-19}} \approx 90). Therefore, the atomic number of the nucleus is 90, which corresponds to the element thorium (Th). The mass provided does not directly affect the atomic number in this context.
What is mass and charge of a proton?
The mass of a proton is approximately 1.67 x 10^-27 kilograms, which is roughly 938 times the mass of an electron. The charge of a proton is positive and equal in magnitude to the charge of an electron, which is around 1.6 x 10^-19 coulombs.
What do we now know to be the basis for the observations that Henry Moseley made about the pattern of X-ray frequencies emitted from elements?
Henry Moseley's observations regarding the pattern of X-ray frequencies emitted from elements were based on the relationship between the emitted X-ray wavelengths and the atomic number of the elements. He found that each element emits X-rays at specific frequencies that correlate with its atomic number, rather than its atomic mass. This led to the realization that atomic number is a more fundamental property than atomic mass, ultimately leading to the reorganization of the periodic table by atomic number instead of mass. Moseley's work provided a clearer understanding of atomic structure and the periodic law.
What is X-ray diffraction and why it is used?
X-ray diffraction is an investigative technique that involves directing a beam of X-rays at a material and examining the ways in which those X-rays were scattered by that material. The patterns into which they scatter and the angles of scattering reveal information about the structure of the material being studied. The application of X-ray diffraction to probe characteristics of a material allows a researcher to model the atomic or molecular structure of that material.
Is the smallest quantity of electric charge represented by the letter c?
No, the smallest quantity of electric charge is represented by the letter "e" and is approximately equal to 1.6 x 10^-19 coulombs. The letter "c" typically represents the speed of light in equations in physics.
What did Millikan Contributed at the atomic structure?
Robert A. Millikan was an American experimental physicist. He measured the charge on the electron. (minus 1.602 176 53(14) x 10−19 coulomb)
What is the charge of a nucleus?
The nucleus of an atom is always positively charged. The magnitude of the positive charge is proportional to the atomic number of the element. For instance, the charge on a nucleus of Hydrogen is +1 or +1.6 x 10-19 C as the atomic number of Hydrogen is 1. The charge on a nucleus of carbon (at. no. =6) is +6 or +6 x 1.6 x10-19 C

What elements in the periodic table start with the letter x?
Only one element in the entire periodic table starts with the letter X, and it is Xenon (Atomic Number 54, Atomic Mass of 131.30, and Electronic Configuration of [Kr]5s24d105p6 ).
What electric charges are not observed in matter on the atomic scale?
Only integer multiples of the elementary charge (1.6 x 10^-19 coulombs) are observed in matter on the atomic scale. Non-integer or half-integer values of charge are not observed in nature.
Are x ray diffracted by?
Yes, X-rays can be diffracted by crystalline materials. This diffraction occurs when X-rays interact with the periodic atomic structure of the crystal, causing them to scatter in specific directions. The resulting pattern can be analyzed to provide information about the crystal's structure, such as the arrangement of atoms and the distances between them. This principle is widely used in X-ray crystallography for determining molecular and atomic structures.
