What is an element? What is a free radical?Atom:The smallest part of a living or non-living thing consists of a central nucleus surrounded by one or more electrons is called an atom. The number of protons present in the nucleus of an atom is designated as an atomic number of an ...
However, this would require volatilizing roughly 100,000 megatons of fluorine, an element that is scarce on the red planet’s surface. This means that essentially all the fluorine required would need to be transported to Mars from somewhere else – something that is not really feasible. An ...
To summarize: fluorine is an element; fluoride is an ion or a compound which contains the fluoride ion. Fluorides are found in toothpaste and added to public drinking water in some countries.Water fluoridationusually is accomplished by adding sodium fluoride (NaF), fluorosilicic acid (H2SiF6),...

electronegativity. As you move from left to right, electronegativity increases. Ã’šÃ‚ This means that oxygen is one of the most electronegative elements because it is situated on the right part of the periodic table. Next to fluorine which has 4. 0 electronegativity, oxygen has ...
