Cancer – Physical – Heart: ELEMENTAL

An element is a pure substance that can no longer be separated into simpler substances by chemical methods (reactions). Each chemical element is made up of atoms with the same chemical properties such as reactivity, ionization potential…. The chemical elements are identified by names given in antiquity, derived from some property of the elements, the name of their discoverer, the place of discovery… In nature there are 92 elements that can be presented (at 1 atm of pressure and 25 ºC) as solid: iron, lead; liquid: bromine, mercury, or gas: chlorine, oxygen… In laboratories it has been possible to synthesize some elements such as technetium.

Different chemical elements have different properties that characterize them, but there are some that make them similar. These latter properties allow us to classify them into metals and nonmetals.

Metals: – They are solids at room temperature (except mercury). – They reflect light in a characteristic way (metallic luster). – They are ductile since they can be stretched into threads. – They are malleable since they can easily be made into sheets or plates.

Non-metals: – They have no metallic luster. – They can be solids, liquids, or gases at room temperature. – They do not conduct electricity. – In general, they are fragile.

According to the atomist theories, the particle that can no longer be divided is called atom. An atom that acquires or loses electrons becomes charged and is called an ion. Atoms can join together to form crystals or molecules. A molecule is formed by the union of two or more atoms of the same or different elements. A crystal is an ordered structure of atoms, molecules, or ions. Remember that true solids are all crystals.

I invite everyone to read Matias’ post with the topic of the day.

Finally, I encourage everyone to reflect on the concept of the day. No one else but us can re-signify our own being
