Atoms & Elements
In chemistry, you will often here the term blood corpuscle thrown into, roughly, e rattling treatment or every lesson. To understand exactly what an atom is, you should sprout a look around everything that you come into contact with. From the food we eat to the fabrics and fibers in our clothing, they be all made of atoms. i interesting fact to note, even the air we breathe has atoms disregardless of the fact that we are not able to even canvas it. In this paper, I will be describing the periodic elude as well as its designer, Dmitri Mendeleev. I will excessively be discussing the periodic nature and properties of atoms and elements; how the halogens and alkali metals are exceedingly reactive; and how the noble gases are not reactive.
Like many of todays charts and organized tables, the periodic table had very many precursors but majority of the outcome is credited to Russian chemist and inventor Dmitri Mendeleev in 1869. The original scheme bottom the periodic table was to organize the elements by their weight. As Dmitri began organizing the elements, he noticed sameities in their properties. Dmitri then decided to centralize the equal elements and group them into families.
Below, you will feel a modern transformation of the period outlining the different element families by the mask coding.

Figure 1 is an example of a modern sport of the periodic table in which the elements are grouped and color coordinated. Grouped in yellow, on the far-left side of the table, you will find the set of the alkali metals. These metals are caesium (Cs), rubidium (Rb), atomic number 3 (Li), sodium (Na), francium (Fr), and Potassium (K). These alkali metals are similar in the fact that they all have one atom in their outer shell and have very squiffy reactions when put into contact with other elements. Apart from their reactive properties, these metals are often identified by their shiny and silvery...If you want to lose a full essay, order it on our website: Orderessay
