Where did the story of man and sodium come from?

Aside from being an essential nutrient, the story of man and sodium is said to begin all the way back in the time of the Pharaohs in Ancient Egypt, with the first recorded mention of a sodium compound in the form of hieroglyphics. It is difficult to describe a pictogram through speech but imagine a squiggly line over the top of a hollow eye-shape, over the top of a semicircle, with a left-facing vulture image next to them all. This pictogram meant divine or pure and its name is the root of the word natron, which was used to refer to washing soda, or sodium carbonate decahydrate, as we would know it today. Sodium carbonate was used in soap, and also, in the process of mummification thanks to its water absorbing and bacteria killing pH control properties.

What is sodium made of?

Sodium in the form of salt (sodium chloride, NaCl) and soda (sodium carbonate, Na2CO3) have been known since prehistoric times [1] The name of element originated from Arabic word ‘suda’ which means headache, as the association of sodium with headache was known in early times. The metal was first isolated in 1807, through the electrolysis of sodium hydroxide by Sir Humphry Davy. In 1809, Ludwig Wilhelm, a German physicist and chemist, proposed the name Natronium for it. Its chemical abbreviation ‘Na’ was published in the system of atomic symbols in 1814 which is derived from its Latin name ‘natrium’ [2].

How are sodium compounds used in the paper making process?

Firstly, they’re used to produce paper. In the paper-making process, sodium hydroxide treats/separates fibers in the pulling phase. Secondly, they’re used to produce clear glass. In this process, we heat sodium carbonate with calcium oxide. Thirdly, sodium compounds are used in creating different metals. For example, sodium combined with titanium tetrachloride produces titanium metal. In another reaction, sodium is a catalyst to create artificial rubber. Similarly, there are other materials (e.x. foodstuffs and fertilizer) which involve sodium in their production/usage.

Why does sodium float on water?

To begin with, sodium floats when placed on water. This is because sodium’s density is lower than that of water’s. Subsequently, an exothermic reaction will occur, and a solution of sodium hydroxide and hydrogen gas will form. This reaction releases so much heat that the sodium melts and releases the hydrogen from the added water. Further, this released hydrogen gas can catch fire.

Can periodic table games be used for grade?

The periodic table game available on this page is for entertainment purposes only, and should not be used to grade students on their knowledge of chemical elements.

Who created the periodic table?

The creator of the periodic table, Dmitri Mendeleev, in 1869 began collecting and sorting known properties of elements, like he was playing a game, while traveling by train.

Did Mendeleev's predictions get dismissed?

There were plenty of skeptics and it took years to gain international acceptance, but once newly-discovered elements matched the ones that Mendeleev predicted, his patterns could not be dismissed. In addition, some of the properties that he "fudged" were later recalculated and found to be much closer to his predictions.

How many protons and electrons are in hydrogen?

Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure. The chemical symbol for Hydrogen is H.

How are atomic nuclei determined?

Properties of atomic nuclei (atomic mass, nuclear cross-sections) are determined by the number of protons and number of neutrons (neutron number). It must be noted, especially nuclear cross-sections may vary by many orders from nuclide with the neutron number N to nuclide with the neutron number N+1. For example, actinides with odd neutron number are usually fissile (fissionable with slow neutrons) while actinides with even neutron number are usually not fissile (but are fissionable with fast neutrons). Heavy nuclei with an even number of protons and an even number of neutrons are (due to Pauli exclusion principle) very stable thanks to the occurrence of ‘paired spin’. On the other hand, nuclei with an odd number of protons and neutrons are mostly unstable.

What are the two forces that make up the nucleus?

Atomic nuclei consist of protons and neutrons, which attract each other through the nuclear force, while protons repel each other via the electric force due to their positive charge. These two forces compete, leading to various stability of nuclei. There are only certain combinations of neutrons and protons, which forms stable nuclei.

What is the charge of an atom?

Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. In a neutral atom there are as many electrons as protons moving about nucleus. It is the electrons that are responsible for the chemical bavavior of atoms, and which identify the various chemical elements.

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.

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 is the Pauli exclusion principle?

It is the Pauli exclusion principle that requires the electrons in an atom to occupy different energy levels instead of them all condensing in the ground state. The ordering of the electrons in the ground state of multielectron atoms, starts with the lowest energy state (ground state) and moves progressively from there up the energy scale until each of the atom’s electrons has been assigned a unique set of quantum numbers. This fact has key implications for the building up of the periodic table of elements.
