atom: The essential unit of a chemical ingredient. Atoms are made up of a dense nucleus that comprises positively charged protons and uncharged neutrons. The nucleus is orbited by a cloud of negatively charged electrons.

bond: (in chemistry) A semi-permanent attachment between atoms — or teams of atoms — in a molecule. It’s shaped by a pretty power between the taking part atoms. As soon as bonded, the atoms will work as a unit. To separate the element atoms, power have to be provided to the molecule as warmth or another sort of radiation.

carbon: A chemical ingredient that’s the bodily foundation of all life on Earth. Carbon exists freely as graphite and diamond. It is a vital a part of coal, limestone and petroleum, and is able to self-bonding, chemically, to type an unlimited variety of chemically, biologically and commercially essential molecules. (in local weather research) The time period carbon generally will likely be used virtually interchangeably with carbon dioxide to connote the potential impacts that some motion, product, coverage or course of might have on long-term atmospheric warming.

carbon dioxide: (or CO2) A colorless, odorless fuel produced by all animals when the oxygen they inhale reacts with the carbon-rich meals that they’ve eaten. Carbon dioxide is also launched when natural matter burns (together with fossil fuels like oil or fuel). Carbon dioxide acts as a greenhouse fuel, trapping warmth in Earth’s ambiance. Vegetation convert carbon dioxide into oxygen throughout photosynthesis, the method they use to make their very own meals.

chemistry: The sector of science that offers with the composition, construction and properties of gear and the way they work together. Scientists use this information to check unfamiliar substances, to breed massive portions of helpful substances or to design and create new and helpful substances. (about compounds) Chemistry is also used as a time period to discuss with the recipe of a compound, the best way it’s produced or a few of its properties. Individuals who work on this area are referred to as chemists. (in social science) A time period for the flexibility of individuals to cooperate, get alongside and revel in one another’s firm.

compound: (typically used as a synonym for chemical) A compound is a substance shaped when two or extra chemical components unite (bond) in mounted proportions. For instance, water is a compound fabricated from two hydrogen atoms bonded to 1 oxygen atom. Its chemical image is H2O.

pc chip: (additionally built-in circuit) The pc element that processes and shops info.

diamond: One of many hardest recognized substances and rarest gems on Earth. Diamonds type deep throughout the planet when carbon is compressed beneath extremely sturdy strain.

DNA: (quick for deoxyribonucleic acid) A protracted, double-stranded and spiral-shaped molecule inside most residing cells that carries genetic directions. It’s constructed on a spine of phosphorus, oxygen, and carbon atoms. In all residing issues, from crops and animals to microbes, these directions inform cells which molecules to make.

fats: A pure oily or greasy substance occurring in crops and in animal our bodies, particularly when deposited as a layer beneath the pores and skin or round sure organs. Fats’s main function is as an power reserve. Fats additionally is an important nutrient, although it may be dangerous if consumed in extreme quantities.

graphene: A superthin, superstrong materials comprised of a single-atom-thick layer of carbon atoms which are linked collectively.

hydrogen: The lightest ingredient within the universe. As a fuel, it’s colorless, odorless and extremely flammable. It’s an integral a part of many fuels, fat and chemical substances that make up residing tissues. It’s fabricated from a single proton (which serves as its nucleus) orbited by a single electron.

inorganic: An adjective for some chemical substance that doesn’t comprise carbon from residing organisms.

metallic: One thing that conducts electrical energy effectively, tends to be shiny (reflective) and is malleable (that means it may be reshaped with warmth and never an excessive amount of power or strain).

mineral: Crystal-forming substances that make up rock, comparable to quartz, apatite or numerous carbonates. Most rocks comprise a number of totally different minerals mish-mashed collectively. A mineral normally is strong and secure at room temperatures and has a selected system, or recipe (with atoms occurring in sure proportions) and a selected crystalline construction (that means that its atoms are organized in common three-dimensional patterns). (in physiology) The identical chemical substances which are wanted by the physique to make and feed tissues to take care of well being.

molecule: An electrically impartial group of atoms that represents the smallest attainable quantity of a chemical compound. Molecules might be fabricated from single sorts of atoms or of various varieties. For instance, the oxygen within the air is fabricated from two oxygen atoms (O2), however water is fabricated from two hydrogen atoms and one oxygen atom (H2O).

natural: (in chemistry) An adjective that signifies one thing is carbon-containing; additionally a time period that pertains to the fundamental chemical substances that make up residing organisms. (in agriculture) Farm merchandise grown with out using non-natural and doubtlessly poisonous chemical substances, comparable to pesticides.

oxide: A compound made by combining a number of components with oxygen. Rust is an oxide; so is water.

prime: (in chemistry and engineering) Make prepared or put together to be used or motion.

protein: A compound comprised of a number of lengthy chains of amino acids. Proteins are an important a part of all residing organisms. They type the idea of residing cells, muscle and tissues; additionally they do the work inside cells. Among the many better-known, stand-alone proteins are the hemoglobin (in blood) and the antibodies (additionally in blood) that try and battle infections. Medicines continuously work by latching onto proteins.

salt: A compound made by combining an acid with a base (in a response that additionally creates water). The ocean comprises many alternative salts — collectively known as “sea salt.” Frequent desk salt is a fabricated from sodium and chlorine.

silicon: A nonmetal, semiconducting ingredient utilized in making digital circuits. Pure silicon exists in a shiny, dark-gray crystalline type and as a shapeless powder.
