atom: The fundamental unit of a chemical ingredient. Atoms are created up of a dense nucleus that has positively billed protons and uncharged neutrons. The nucleus is orbited by a cloud of negatively billed electrons.

atomic: Getting to do with atoms, the smallest achievable device that can make up a chemical element.

bond: (in chemistry) A semi-everlasting attachment between atoms — or teams of atoms — in a molecule. It’s shaped by an interesting pressure involving the participating atoms. Once bonded, the atoms will operate as a device. To different the ingredient atoms, energy need to be supplied to the molecule as heat or some other form of radiation.

chemical: A substance fashioned from two or additional atoms that unite (bond) in a preset proportion and structure. For case in point, water is a chemical manufactured when two hydrogen atoms bond to 1 oxygen atom. Its chemical formulation is H2O. Chemical also can be an adjective to describe properties of components that are the consequence of several reactions amongst distinct compounds.

chemical bonds: Interesting forces in between atoms that are strong ample to make the connected components purpose as a solitary device. Some of the interesting forces are weak, some are incredibly powerful. All bonds look to url atoms by means of a sharing of — or an try to share — electrons.

chemical engineer: A researcher who utilizes chemistry to remedy challenges related to the creation of food, fuel, medications and a lot of other merchandise.

element: A thing that is portion of a little something else (this kind of as parts that go on an electronic circuit board or components that go into a cookie recipe).

compound: (frequently used as a synonym for chemical) A compound is a substance fashioned when two or extra chemical components unite (bond) in set proportions. For instance, drinking water is a compound made of two hydrogen atoms bonded to just one oxygen atom. Its chemical image is H2O.

standards: (sing. criterion) The requirements, regulations, characteristics or other points used to make a judgment or resolve about anything.

degrade: To crack down into scaled-down, more simple components — as when wooden rots or as a flag which is still left outdoors in the climate will fray, fade and fall apart. (in chemistry) To break down a compound into smaller sized elements.

dynamic: An adjective that signifies something is energetic, changing or transferring. (noun) The alter or selection of variability witnessed or calculated within some thing.

engineer: A man or woman who uses science to remedy issues. As a verb, to engineer suggests to layout a gadget, product or system that will address some challenge or unmet need to have. (v.) To accomplish these duties, or the name for a person who performs these types of responsibilities.

ecosystem: The sum of all of the items that exist all-around some organism or the course of action and the problem all those items generate. Ecosystem may possibly refer to the climate and ecosystem in which some animal lives, or, probably, the temperature and humidity (or even the placement of items in the vicinity of an merchandise of interest).

pressure: Some outdoors impact that can improve the motion of a system, maintain bodies close to one particular yet another, or create motion or anxiety in a stationary body.

glass: A difficult, brittle material produced from silica, a mineral found in sand. Glass usually is transparent and reasonably inert (chemically nonreactive). Aquatic organisms identified as diatoms establish their shells of it.

insulator: A material or product that does not readily conduct energy.

landfill: A web site in which trash is dumped and then covered with filth to minimize smells. If they are not lined with impermeable resources, rains washing via these squander web pages can leach out poisonous products and have them downstream or into groundwater. Because trash in these facilities is included by dirt, the wastes do not get prepared access to sunlight and microbes to aid in their breakdown. As a end result, even newspaper despatched to a landfill might resist breakdown for several many years.

backlink: A relationship involving two people today or things.

liquid: A product that flows freely but retains a constant volume, like water or oil.

macro: (antonym: micro) An adjective that indicates on a significant or wide scale. (in computing) Pc code to execute a solitary instruction, which in convert directs the personal computer to use some preset guidelines to execute a specific, desired job.

mechanical: Owning to do with the devices that shift, such as tools, engines and other machines (even, potentially, dwelling equipment) or a thing prompted by the actual physical motion of one more point.

steel: Anything that conducts energy properly, tends to be shiny (reflective) and malleable (meaning it can be reshaped with heat and not also much drive or stress). 

microplastic: A modest piece of plastic, 5 millimeters (.2 inch) or lesser in sizing. Microplastics may perhaps have been manufactured at that smaller measurement, or their measurement could be the final result of the breakdown of h2o bottles, plastic baggage or other matters that started off out greater.

molecule: An electrically neutral team of atoms that represents the smallest probable total of a chemical compound. Molecules can be made of single types of atoms or of distinctive kinds. For case in point, the oxygen in the air is created of two oxygen atoms (O2), but h2o is produced of two hydrogen atoms and one particular oxygen atom (H2O).

particle: A moment amount of money of a little something.

plastic: Any of a collection of components that are quickly deformable or artificial resources that have been designed from polymers (prolonged strings of some creating-block molecule) that tend to be lightweight, economical and resistant to degradation.

pollutant: A substance that taints a thing — this kind of as the air, h2o, our bodies or products and solutions. Some pollutants are substances, such as pesticides. Other people may be radiation, which include excess heat or gentle. Even weeds and other invasive species can be thought of a type of biological pollution.

polymer: A compound created from extensive chains of repeating teams of atoms. Manufactured polymers involve nylon, polyvinyl chloride (improved regarded as PVC) and numerous types of plastics. Normal polymers include things like rubber, silk and cellulose (identified in vegetation and applied to make paper, for example).

radical: A molecule possessing a person or more unpaired outer electrons. Radicals conveniently get component in chemical reactions. The body is capable of generating radicals as just one usually means to get rid of cells, and thus rid by itself of weakened cells or infectious microbes.

recycle: To come across new employs for a thing — or elements of anything — that could otherwise be discarded, or addressed as squander.

stable: Company and steady in shape not liquid or gaseous.

vitrimer: A class of polymers 1st documented in 2011 that blend the houses of the two glass and plastics.

waste: Any supplies that are remaining above from organic or other systems that have no value, so they can be disposed of as trash or recycled for some new use.

wind turbine: A wind-powered machine — very similar to the type used to mill grain (windmills) extended back — used to make electricity.

zinc: A metallic aspect that in its pure variety is ductile (simply deformed) and that is an important micronutrient in crops and animals.
