Atomic number

The atomic number for Neon is 10, keeping in mind that the atomic number is the number of protons in an element. The atomic mass of Neon is 20.180, which when rounded up will become an atomic mass of 20. The state of matter Neon is mainly in is a gaseous state. The full electron configuration of neon is 1s2 2s2 2p6, and the abbreviated electron configuration…

Chromium got this name because of the many different colors in the element. This element is hard, metallic and shiny. Chromium doesn't tarnish. Chromium is a metal element. Chromium's symbol is "Cr" and has an atomic number of 24. This metal is the first element in group 6. It has an Atomic mass of 52.0. Chromium has 4 known isotopes. Chromium is a "transitional metal." The other family members in period 6 are molybdenum (Mo), tungsten (W), and seaborgium (Sg). All elements in group 6 are…

The element Titanium is a very light metal and it’s in the periodic table group 4. This element is a transition metal and the symbol is Ti. The color of titanium is a silver grey and white color. The atomic mass is 47.867 and atomic number is 22. This element however is resistant to chlorine, and sea water. It has 22 electrons, 22 protons, and 26 neutrons. The density is 4.54 The discoverer who found titanium is William Gregor a Mineralogist. The year it was discovered was in 1791. Where it had…

12-18-14 Subject: Honors Chemistry / Period 5 Introduction: The periodic table is a table of the chemical elements in which the elements are arranged by order of a atomic number. The periodic table also has a special name for its vertical columns. Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every…

Lab Web). However, even though this element was found by Arfvedson, William Thomas Brande and Sir Humphrey Davy were the first people to isolate it (Jefferson Lab Web). Lithium is very abundant, it is a soft silver white alkali metal with the atomic number of three. Lithium is silver and contains no odor (Element Project). In addition to those features, lithium has a total of seven isotopes, two natural and five unnatural. The two natural occurring isotopes are 6Li (7.59% abundance) and 7Li…

I am researching the element, boron. The symbol of boron is a just a capital B. The atomic number of boron is 5. Boron’s mass is 10.811 grams. Boron has 5 protons, 6 neutrons, and 5 electrons. The Periodic Table lists elements in numerical order from the smallest atomic number to the largest atomic number. That is why boron is the 5th element on the Periodic Table. It comes after beryllium and before carbon. Boron was discovered on June 30th in 1808. It was discovered by French chemists,…

discovered in 1984 by Peter Armbruster and Gottfried Munzenburg. These two inventors developed this element in Darmstadt, Germany which is located in Europe. Hassium has a atomic number of 108 as it is the 108th element on the periodic table. Hassium atomic symbol is simply just a capital h and a lowercase s “Hs”. The atomic mass of Hassium is rounded to 270, although some sources could say it is 269. Hassium is located…

How are elements useful for a particular use? An element is made from one type of atom and this article is about the element Scandium. Scandium was discovered in the year 1879 by Scientist Lars Fredrik Nilson in the university of Uppsala. The origin of the name comes from the word Scandia, which is the latin name for Scandinavia. This element belongs to group 3 which consists of transition metals and Scandium shares this group with the element Yttrium. There are 4 groups in the periodic table…

made the discovery by heating up potassium and silica in which then isolated silicon. Silicon natural occurring form is never by itself is usually paired with oxygen molecules. It can be found in sand, rock crystals, quartz, and flint. Silicon atomic number in the…

The element I selected for the Element Research Project is Osmium. Osmium’s chemical symbol is Os. Osmium’s atomic mass is 190 amu. Osmium’s atomic number is 76, it has 76 protons and 76 electrons. Osmium also has 114 neutrons. Osmium belongs to the transition metal group in the middle of the periodic table. Osmium’s Bohr model with electric configuration has two electrons in the first shell, eight in the second shell, eighteen is the third shell, thirty two in the fourth shell, fourteen in the…
