Give an example of the use of such a tracer in chemistry.Nuclear Chemistry:Nuclear chemistry is a field of chemistry that deals with the concept of radioactivity and different nuclear processes and transformations. Understanding nuclear chemistry can pave way for the safe a...
Atom is the smallest particle of matter which may or may not exist independently. Molecule is the smallest particle of matter which can have independent existence. Inert gases exist in atomic state. Oxygen, nitrogen etc. exist in molecular from.
To construct a mapping from set B to set A, we need to assign each element in set B to an element in set A. Given: - Set A = {2, 3, 4} - Set B = {2, 5, 6, 7}1. Identify the Sets: - We have two sets: A and B. - Set

The atomic number of an atom is always equal to the number of protons that are found in that atom. This number can typically be found on a periodic table above the symbol in an element's box. The number of protons in an atom is similar to the DNA of a human; it is responsible ...
Kristin has an M.S. in Chemistry and has taught many at many levels, including introductory and AP Chemistry. Electronegativity and Its Periodic Trends Electronegativityis an atomic property that defines the attraction of the atom for the electron within a chemical bond. It plays an important role...
It helps in the determination of valence of an element. It helps to predict the properties of a group of elements with similar configurations of electrons and properties. It helps in the interpretation of atomic spectra. The notation which is to be followed when an atom's electronic configuratio...
Amolarratio is the ratio between the amounts inmolesof any twocompoundsinvolved in achemical reaction. Molar ratios are usedas conversion factorsbetween products andreactants in many chemistry problems. The molar ratio may be determined by examining the coefficients in front of formulas in a ...
