Periodic table

observe arrangements and trends on the periodic table. Finally, the main goal is to draw conclusions and identify the locations of unknown elements based on given trends and properties. Through observing characteristics and trends, one is introduced to reading the periodic table and its elements, based on how it is arranged. Dmitri Mendeleev was a Russian scientist who is credited with creating the first periodic table. The Russian scientist’s first table included missing, unknown elements,…

He is known for his work on the Periodic Law and the creation of the very first periodic table. Mendeleev dedicated many years of his life to collecting information about all the 63 elements that had been discovered during his time. Mendeleev had noticed that there were groups of different elements with very similar atomic masses and other chemical properties. Mendeleev had created the periodic law which is a law stating that the elements, when listed in order of…

Holmium is a brilliant dim metal found in the lanthanide section on the periodic table, which is for the most part appeared at the bottom of the periodic table. This element has 67 protons in its nucleus, which implies it is the 67th component on the periodic table. Holmium is pliable, which infers it can be bowed and folded. It is the foremost magnetic component of the periodic table. The name comes from the element lanthanum. The lanthanides are also known as rare earth elements. Although…

my knowledge of the periodic table to determine the identity and physical properties of each unknown element. To find the unknown elements we looked at the characteristics of the other elements and grouped the ones that were similar and belonged in the same column. By looking at the characteristics of the unknown elements if it seemed to belong in a group with others with a blank we assumed it belonged there. Mendeleev was a scientist who came up with the original periodic table which he…

toward the creation of the periodic table. When finding the unknown elements we used other known elements as guides and looked for similar properties. Like the Periodic Table today, it is organized through similar properties of each element and categorized in groups. Dimitri Mendeleev was a chemist from Russia who lived in poverty and was the only one of seventeen siblings to attend school. Mendeleev then created the first periodic table from his finding through periodic law, which he also…

The purpose of this lab was to analyze and examine periodic trends of the first 36 elements that are on the periodic table. Trends that were analyzed and examined are the atomic radius (AR) and the first ionization energy (IE) of the 36 elements. The hypothesis for this lab was that the elements that are in the groups that had the highest atomic radius would be in the same groups as those who have the the highest first ionization energy and the groups who have the lowest atomic radius would be…

the periodic table in depth. Within the first nine chapters of the novel, Kean explains the importance of location on the table, origin and discovery of each element, and its impact on other aspects of human life. Through various tales, the table is pulled apart and analyzed in an ingenious way. To a reader, it is interesting to follow how our life is determined by the elements of the periodic table, as they can create, heal, or destroy our entire world. To begin, Kean introduces the periodic…

Introduction Fluorine is the 9th element on the periodic table. It is a light yellow gas and is most commonly known for helping your teeth. I choiced this element because it has the highest electronegativity. But what other traits does fluorine have? Read my ABC book and find out. A is for… Atomic number The atomic number of fluorine is 9. The most common isotope of fluorine is 19F and 18F. Fluorine is more stable in when it has 10 neutrons. Fluorine is a halogen and is placed on…

Before talking about the elements, the atom must be discussed first. Atoms are the building blocks of everything—from the structures of a building to a household pet. The idea of the atom was first suggested by Democritus, a Greek philosopher born in 460 BC. Democritus hypothesized “that atoms were indivisible and infinite in size and shape as well as firm and completely solid” and that they “existed in a void moving about combining and recombining” (European Graduate School). Later on, a…

The Periodic table is a table that organizes the different known elements, and Neon is one of those elements. Neon is an element that is a non-metal and also a noble gas. The start of the element, Neon, was when a Scottish chemist named William Ramsay discovered Neon, Krypton, and Argon, which are all noble gasses ("Periodic Table of Elements: Los Alamos National Laboratory." Periodic Table of Elements: Los Alamos National Laboratory). For this achievement, William Ramsay won the Nobel Prize in…
