A decrease in the radii of the elements following the lanthanides compared to what would be expected if there were no f-transition metals.
- Diamonds Are Forever
Diamonds are still a girl's best friend, right? We love the shiny gems. They are the most popular rocks sold today. But what exactly are they, anyway? Where do they come from? What else are they used for?
- Chemical Safety
People use chemicals every day for a wide array of purposes, which can include work and house hold duties. Many of us fail to realize that we are actually handling potentially deadly chemicals when we simply clean the bathroom or wash the car. This brings to mind the reason why chemical safety is...
- What are Compound Microscopes?
Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...
- Harmful Chemicals Found In Food
It's getting close to New Years and many people are starting to think about how to lose those extra pounds they managed to gain over the holidays. There are many sorts of diets and fads that have developed over the years from cutting carbs to cutting protein. Everyone has their own opinion as to...
- What's In Your Beverage? How to Ensure Quality Control with CO2 Analytical Support
Calibration standards, performance audits, and the FDA's never-ending safety, labeling, and inspection requirements are just the tip of the iceberg when it comes to dealing with the increasingly stringent quality control standards of the beverage industry. As these quality standards become...
A compound that can be imagined to arise from a partent compound by replacement of one atom with another atom or group of atoms. Used extensively in orgainic chemistry to assist in identifying compounds.
Method by which hydrophobic (water-repelling) particles of an ore are separated from hydrophilic (water-attracting) particles of a metallurgical pretreatment process.
Placing a thin layer of zinc on a ferrous material to protect the underlying surface from corrosion.
Lead Storage Battery
Secondary voltaic cell used in most automobiles.
Trapping of heat at the surface of the earth by carbon dioxide and water vapour in the atmosphere.
Refers to the overall processes by which metals are extracted from ores.
Absorption of a K shell (n=1) electron by a proton as it is converted to a neutron.
Aufbau ('building up') Principle
Describes the order in which electrons fill orbitals in atoms.
A gas formed by boiling or evaporating a liquid.
The buildup of a product of oxidation or a reduction of an electrode, preventing further reaction.
Chemical Hygiene Officer (CHO)
A person or employee who is qualified by training or experience to provide technical guidance in the development and implementations of the provisions of a Chemical Hygiene Plan (CHP)
Reactions in which oxidation and reduction occur, also called redox reactions.
A compound containing oxygen in the -1 oxidation state. Metal peroxides contain the peroxide ion, O22
A solid characterized by a regular, ordered arrangement of particles.
Attraction toward a magnetic field, stronger than diamagnetism, but still weak compared to ferromagnetism.
Corrects standard electrode potentials for nonstandard conditions.
The concept in which two or more equivalent dot formulas for the same arrangement of atoms (resonance structures) are necessary to describe the bonding in a molecule or ion.
Describes processes that absorb heat energy.
Adhesion of a species onto the surfaces of particles.
Energy that is propagated by means of electric and magnetic fields that oscillate in directions perpendicular to the direction of travel of the energy.
