Which element has the lowest ionization energy? Which group in the periodic table contains only nonmetals? What is the electronegativity of lithium? What noble gas is used in light bulbs? What inert gas is used in fluorescent lights?
Fluorescent light bulbs use small amounts of liquid mercury as their lighting element, in addition to argon, which is an inert gas that helps to regulate the flow of electricity within the bulb and maintain the amount of light produced by the mercury. When switched on, the electricity flowing...
Silicon: a chemical element and the main material used to create silicon chips and semiconductor devices; used in solar panels. Light-Emitting Diodes (LEDs): a semiconductor that emits light when an electrical current flows through it; often used in LED lights for lamps, digital watches, traff...
A core nucleus of protons and neutrons is surrounded by orbiting electrons. Every atom must have at least one proton in it. The number of protons in an atom is important, because it defines what chemical element the atom represents. For example, an atom with just one proton is hydrogen, ...

Bone is more dense and shows up in the image because the X-rays do not pass through it. X-rays that do pass through the body strike a screen and light it up. The images that you see are negatives. Tungsten Tungsten is the element most commonly used to make X-rays. When an element...
However, humans can also inhale or absorb mercury through their skin. This can happen if the substance leaks or is spilled from a product containing it or a process utilising it. Indeed, a significant percentage of mercury exposure occurs in workplace environments where the...
A name given to some parts that resemble in shape certain bulbous roots; as, the bulb of the aorta. Lamp A device or mechanism for producing light by electricity, usually having a glass bulb or tube containing the light-emitting element. Most lamps belong to one of two categories, the Inc...
