What is the periodic table?
The periodic table is a tabular display of the chemical elements organized on the basis of their atomic numbers, electron configurations, and chemical properties. The electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. Knowledge of the electron configuration of different atoms is useful in understanding the structure of the periodic table of elements.
What is the atomic mass of an atom?
The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. The atomic mass is carried by the atomic nucleus, which occupies only about 10 -12 of the total volume of the atom or less, but it contains all the positive charge and at least 99.95% of the total mass of the atom. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance.
How to determine the stability of an isotope?
To determine the stability of an isotope you can use the ratio neutron/proton (N/Z). Also to help understand this concept there is a chart of the nuclides, known as a Segre chart. This chart shows a plot of the known nuclides as a function of their atomic and neutron numbers. It can be observed from the chart that there are more neutrons than protons in nuclides with Z greater than about 20 (Calcium). These extra neutrons are necessary for stability of the heavier nuclei. The excess neutrons act somewhat like nuclear glue. Only two stable nuclides have fewer neutrons than protons: hydrogen-1 and helium-3.
What are phonons in crystals?
The quanta of the crystal vibrational field are referred to as ‘‘ phonons .’’ A phonon is a collective excitation in a periodic, elastic arrangement of atoms or molecules in condensed matter, like solids and some liquids. Phonons play a major role in many of the physical properties of condensed matter, like thermal conductivity and electrical conductivity. In fact, for crystalline, nonmetallic solids such as diamond, k ph can be quite large, exceeding values of k associated with good conductors, such as aluminum. In particular, diamond has the highest hardness and thermal conductivity (k = 1000 W/m.K) of any bulk material.
Is potassium an alkali metal?
Potassium was first isolated from potash, the ashes of plants, from which its name derives. In the periodic table, potassium is one of the alkali metals. All of the alkali metals have a single valence electron in the outer electron shell, which is easily removed to create an ion with a positive charge – a cation, which combines with anions to form salts. Naturally occurring potassium is composed of three isotopes, of which 40K is radioactive. Traces of 40K are found in all potassium, and it is the most common radioisotope in the human body.

Does potassium help with dysmenorrhea?
There is some evidence that potassium may alleviate symptoms of dysmenorrhea. A 2009 placebo-controlled study published in "The Journal of Pain" assessed the effect of diclofenac potassium, a nonsteroidal anti-inflammatory agent, on exercise performance in 12 young women with dysmenorrhea. The study found that treatment with the potassium-based drug enabled the young women to perform during their periods at levels similar to the nonperiod, no-pain phase of their cycles, while the placebo group's physically performance was significantly decreased. Fruits and vegetables offer the richest sources of dietary potassium, according to the Linus Pauling Institute.

Can you take potassium without a doctor?
You must not use potassium supplements without consulting a doctor because both low and high levels of the mineral may lead to serious complications that affect your heart, muscles and nervous system. Make sure that the supplements have been approved by the Food and Drug Administration or the United States Pharmacopeial Convention for safety and efficacy.
Can low potassium cause cramps?
Low potassium levels may lead to menstrua l cramps in some women, and taking potassium may be helpful, according to the University of California, Santa Barbara. Ask your doctor if you need potassium supplements while taking diuretic medications for PMS.
