Hello and welcome to Teach Kids Chemistry! Today, we will be exploring one of the most important elements in the periodic table – nitrogen. Nitrogen is a non-metallic element that makes up about 78% of the Earth’s atmosphere. It is essential for life as it is a key component of proteins and nucleic acids. Join us as we dive into the world of nitrogen and learn about its properties, uses, and importance in our daily lives. Let’s get started!
The Periodic Element Nitrogen Overview
Nitrogen is a chemical element with the symbol N and atomic number 7. It is a nonmetal and belongs to group 15 of the periodic table. Nitrogen has an atomic mass of 14.0067 u and contains 7 protons, 7 electrons, and 7 neutrons. It is located in period 2 of the periodic table and is in the p-block. Nitrogen is a gas at room temperature and is colorless, odorless, and tasteless.Nitrogen has an electronegativity of 3.04 and a specific heat capacity of 1.04 J/g·K. Its melting point is -210.01°C and its boiling point is -195.79°C. Nitrogen has a density of 1.25 g/L at room temperature and pressure. Nitrogen is an essential element for life and is a major component of the Earth’s atmosphere, making up about 78% of the air we breathe. It is also used in the production of fertilizers, as a coolant in the food industry, and in the manufacturing of electronics.
Everyday objects that contain the periodic element nitrogen?
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 everyday objects that contain chemicals, students can learn about chemistry concepts in a relatable and understandable way.
Differences in the periodic element nitrogen 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 nitrogen dangerous or radioactive?
Nitrogen is a non-metallic element that is not dangerous or radioactive. It is a colorless, odorless, and tasteless gas that makes up about 78% of the Earth’s atmosphere. Nitrogen is an essential element for life as it is a component of amino acids, which are the building blocks of proteins. It is also used in the production of fertilizers, explosives, and other chemicals. While nitrogen gas is not harmful to humans, it can displace oxygen in confined spaces and cause asphyxiation. However, nitrogen compounds such as ammonia and nitric acid can be hazardous if not handled properly.
Is the periodic element nitrogen rare and expensive?
No, nitrogen is not a rare or expensive element. In fact, it is the most abundant element in the Earth’s atmosphere, making up about 78% of the air we breathe. Nitrogen is also commonly found in the soil and is an essential nutrient for plant growth. It is used in a variety of industries, including agriculture, food processing, and electronics, and is readily available for purchase in various forms such as liquid nitrogen or nitrogen gas. Therefore, nitrogen is a relatively inexpensive and easily accessible element.
