The period of the cosine function cos(bx) is given by:T2=2π|b| Step 2: Find the least common multiple (LCM) of the periodsFor the function f(x) to be periodic, the periods T1 and T2 must be commensurable, meaning there exists a common period T such that:T=nT1=mT2for some ...
When you think of the word "metals," you are as likely to think about everyday objects and their function as you are chemistry or anything else related to science. Most machines and many structures, for example, are made of one of more metals because of the durability and rigidity these ...

Chemistry Dr. Zohra Sattar Waxali earned her doctorate in chemistry and biochemistry from Northwestern University, specializing in the metallomes of cardiac cells and stem cells, and their impact on biological function. Her research encompasses the development of arsenoplatin chemotherapeutics, stapled pep...
The meaning of the square brackets around certain series of elements in the later periods, the properties of which exhibit typical deviations from the simple periodicity in the first periods, will be mentioned below. Table I. Periodic Table of the Elements Radiation.—The discovery of the ...
The potassium cation (K+) is the major cation in intracellular (inside cells) fluids (sodium is the main extracellular cation). It is essential for nerve and heart function. A normal diet containing reasonable amounts of vegetables contains all the potassium necessary. More biological data......
Is the problem just a poor choice of parameter values? It is not hard to show that, forHirniak’s choice of\(\left\{ k_1,k_2,k_3,k_4,k_5\right\}\), the damping factor over the course of one oscillation, as a function of\(k_6\), is ...
Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in t
University. Elements that occupy the same column on the periodic table (called a "group") have identical valence electron configurations and consequently behave in a similar fashion chemically. For instance, all the group 18 elements are inert gases, meaning they don't react with any other ...
The original table was created without a knowledge of the inner structure of atoms: if one orders the elements by atomic mass, and then plots certain other properties against atomic mass, one sees an undulation or periodicity to these properties as a function of atomic mass. The first to ...
