Periodic table

one of our own. We expanded your portfolio so you have the PES of the elements Titanium and Vanadium, while also providing a full analysis of all of the elements that were tested. We discovered a pattern in which the elements relate back to the periodic table. Our lab also had extra time to provide you with data on how the atomic size corresponds with the PES spectra. For your first request, you asked us to provide the PES for chlorine because yours was…

earth’s crust, ocean and atmosphere. Two of the most abundant elements of the eight are calcium and magnesium. Calcium and magnesium are located on the periodic table located both in group 2 sharing the same family meaning that they share chemical property’s as well as the same valence electron because of their location and family relation to the period table. The alkaline metals are a reactive group of metals and combine with other elements so easily that they are not found on earth in the form…

Mendeleev was a chemist in the 19th century. Dmitri Mendeleev is known for creating the first periodic table of elements. He set the table up in order of atomic mass. When the elements were set up in this style similar elements could be grouped together to show they had similar properties. Since this table was created in the 19th century not all elements were discovered, leaving Mendeleev to leave spaces in the table to later be…

Theq element on the Periodic table that is best representation of my personality would be element 13, Aluminum. Properties of Aluminum its included high melting point, conductivity, malleability, and non-toxicity. Aluminum’s high melting point represents my determined personality. This is because I can face adversity well. Even when situations occur that are extremely unfavorable I am able to keep a cool head and think straight. I can persevere and stay strong allowing myself to solve and get…

What are group one elements? Group one elements are alkali metals. The physical properties of group one elements are that they are shiny and the alkali metals are very soft. Lithium is the hardest alkali metal and they become softer as you go down the group. The chemical properties of group one is that they’re very reactive when mixed with water or when in contact with the air. Each element in group one has one electron in their outermost shell. Also, group one elements get more reactive as you…

Introduction For the most part, the periodic table groups atoms together which are similar in structure and property. Groups or columns share similar electronic configurations, on which a variety of properties are based1. In the lab, the tested elements include those from Group 1, Group 2, Period 3, Period 4, Period 5, Period 6, and a series of metals (Calcium, Copper, Iron, Magnesium, Tin, Zinc). Group 1 elements have one valence electron and are extremely reactive. Most of the time, compounds…

is Cl and its atomic number is 17. Chlorine has the physical form of a diatomic greenish-yellow gas at room temperature and atmospheric pressure. 1. 2. Indeed, its name is derived from the Greek word ‘chloros’, meaning ‘yellow-green’. 3. In the Periodic Table of Elements, Chlorine is found in the P-block, in group 17 and period 3. Chlorine is a non-metal, the second-lightest of the halogen family, which consists of salt-forming elements. 1. 2. Chlorine is 2.5 times as heavy as air. It has a…

Cerium is a rare earth element of the lanthanide series (atomic no. = 57– 71) of the periodic table. Among the various rare earth metals, cerium granted a hugeattention towards scientific community due to its catalytic antioxidant property. Usually, antioxidants protect cells from oxidative damage, mediated by ‘reactive oxygen species’ (ROS), which include free radicals such as superoxide anion (O2•-), hydroxyl radical (•OH), singlet oxygen (1O2) and non-free radical species like hydrogen…

The periodic table of elements contains about 118 elements, and there are also many trends in the periodic table, such as ionization energy, electronegativity, and many other trends. When Dmitri Mendeleev created the periodic table, not all of the elements were present. It took many other scientists to discover the other elements. Mendeleev started to notice the patterns in the properties and atomic weights of halogens, alkali metals, and alkaline metals. He created a card for each of the 63…

In today’s day and age, plastic surgery is extremely popular, especially breast augmentations. About 4% of women in America get breast augmentation each year. One of the options for breast augmentation is silicon implants. That being said I wanted to learn more about silicon and what people are putting in their bodies. Silicon is an element a pure substance that can’t be broken down. Silicon was first discovered in 1824 by a Swedish chemist named Jons Jacob Berzelius. This element is the second…
