When a certain material is illuminated with visible light, electrons jump from lower to higher energy states in atoms of the material. When illuminated by ultraviolet light, atoms are ionized as some of them eject electrons. Why do the two kinds of illumination produce such different results?

A free radical is an atom with an unpaired electron in its shell. But is this what free radical damage actually is ? The free electron has a strong charge that causes it to pair up with one of the electrons of a pair of electrons on the shell of another atom. The extra electron is pushed out and pairs up elsewhere. When the unpaired electron of one atom pairs up with an electron on the shell of another atom, the pull between the two electrons hold or bonds the two atoms together. This type of bonding creates bonds between atoms that ordinarily wouldn’t bond. So is the damage of free radical damage atoms haphazardly being attached to atoms of molecules of structures, and thus changing the structure? Thanks Much

Hoe wordt zuurstof de 3e meest voorkomende element in het universum?

Jack asked:

Ik weet dat Waterstof is de meest voorkomende, dan Helium, toen hoorde ik zuurstof was, maar hoe is zuurstof het meest voorkomende, maar niet dient te worden Lithium de 3e meest voorkomende omdat zij alleen heeft 3 elektronen? Ik bedoel je hoeft alleen maar naar een ander elektron te maken lithium. U moet 8 elektronen om zuurstof dus waarom is het de 3e meest voorkomende? Ook wat zijn de meest voorkomende vorm van obligaties wanneer waterstof maakt helium?

    • Hello world!
    • Well ever since I was born I have been allergic to metal. I cant wear metal watches, metal necklaces, or metal bracelets without breaking out into rashes. I get rashes on my waste right below my belly button from metal button on jeans. I get rashes on my thigh for having change in my pocket to long. I get rashes on my nipple or close to my nipple when Im wearing my name tag at work cause the clip is made from metal and when I was a baby I use to get little cirlce red rashes down the middle of my chest from those metal circle buttons on one piece baby suits. All my life I have had this and so I was wondering is there a technically term for this?
