Hello and welcome to Teach Kids Chemistry! Today, we’re going to explore the fascinating world of the periodic table and take a closer look at one of the newest and most exciting elements discovered to date – Oganesson. We’ll learn about its properties, uses, and why it’s such an important addition to the periodic table. So, let’s dive in and discover the wonders of Oganesson together!
The Periodic Element Oganesson Overview
Oganesson is a synthetic element with the symbol Og and atomic number 118. It was first synthesized in 2002 by a team of Russian and American scientists. Oganesson has an atomic mass of 294, and its nucleus contains 176 neutrons and 118 protons. It has 118 electrons arranged in the electron shells around the nucleus. Oganesson belongs to the noble gas group and is located in period 7 of the periodic table. It is a nonmetal and has an electronegativity of 2.2. The specific heat capacity of oganesson is unknown due to its short half-life, but it is expected to be similar to other noble gases. Oganesson is a solid at room temperature, but its melting and boiling points are unknown due to its short half-life. Its density is also unknown, but it is expected to be similar to other noble gases. Oganesson is a highly unstable element with a half-life of only a few milliseconds. Due to its short half-life, very little is known about its physical and chemical properties. However, it is believed to be a noble gas and is expected to have similar properties to other noble gases such as helium, neon, and argon. Oganesson is not found naturally on Earth and can only be synthesized in a laboratory. Its synthesis requires the fusion of two lighter elements, and it is currently the heaviest element to have been synthesized. Despite its instability, oganesson is an important element in the study of nuclear physics and the properties of super heavy elements.
Everyday objects that contain the periodic element oganesson?
There are many everyday objects that contain chemicals or compounds that can be used to teach chemistry concepts. For example, water is a compound made up of two hydrogen atoms and one oxygen atom, and can be used to teach about chemical formulas and the properties of compounds. Salt, which is made up of sodium and chlorine ions, can be used to teach about ionic bonding and the properties of solutions. Baking soda, which is sodium bicarbonate, can be used to teach about chemical reactions and the properties of acids and bases. Other examples include vinegar, which is acetic acid, and aspirin, which is acetylsalicylic acid. By using these everyday objects, students can learn about chemistry concepts in a simple and relatable way.
Differences in the periodic element oganesson across states of matter
The state of an element can vary greatly depending on its temperature and pressure. At standard temperature and pressure (STP), most elements are either solids or gases. Solids have a fixed shape and volume, while gases have neither. As temperature and pressure increase, some solids can become liquids, which have a fixed volume but take the shape of their container. As temperature and pressure continue to increase, some liquids can become gases, which have neither a fixed shape nor volume. At extremely high temperatures and pressures, some gases can become plasmas, which are highly ionized and conductive. Plasmas are often found in stars and lightning bolts, and have unique properties such as the ability to emit light.
Is the periodic element oganesson dangerous or radioactive?
Yes, oganesson is a highly radioactive element and is considered to be one of the most dangerous elements. It is a synthetic element that was first synthesized in 2002 and has a very short half-life of only a few milliseconds. Due to its high radioactivity, it is not found in nature and can only be produced in a laboratory. Oganesson is classified as a noble gas and is located in the last group of the periodic table. Its properties and behavior are not well understood due to its short half-life, and further research is needed to fully understand its potential uses and dangers.
Is the periodic element oganesson rare and expensive?
Yes, oganesson is a rare and expensive element. It is a synthetic element that was first synthesized in 2002 and has a very short half-life of only a few milliseconds. Due to its rarity and the difficulty in synthesizing it, oganesson is not commercially available and can only be produced in very small quantities in specialized laboratories. As a result, it is one of the most expensive elements to produce, with estimated costs of up to $10 million per microgram.
