③After she had learnt all about physics at university,Marie worked in a lab with her husband,Pierre Curie.During this time,Marie made great progress and discovered two new radioactive elements which had never been seen before.Because of her amazing discoveries and work in scienc...
Check your comprehension of the s-block elements on the periodic table with an interactive quiz and printable worksheet. These practice questions...
I have had student groups build banners on the history of chemistry, design HyperCard stacks (there is an old one for you) on the elements and their compounds, create videos on elements, create 3D models of molecules and ancient Greek matter theorists, do interviews of experts on the history...
Chemistry is one layer but underneath that is atomic physics and that layer is very simple. It’s very simple it has a handful of elements. And these handful of, you know, just a few elements make up all of the chemistry we know 100-some elements in nature that all have unique and ...
Within physics and chemistry, the simplest and purest substances are elements, each being made up of atoms that contain the same number of protons. Around 80% of the elements are considered metals on the periodic table, with the threshold between what is and isn't a metal being only approxim...
Pyrrhotite is mainly filled in the sulfides, or a small amount is distributed in irregular shapes at the edges of the sulfides with cleavage decomposition, mainly hexagonal pyrrhotite. Chalcopyrite, on the other hand, is usually developed on the edges of pentlandite crystals or within inclusions (...
Lead is mainly taken in by respiration through the airways or digestion through the digestive system, with subsequent accumulation in bone, blood, and organs such as the brain, kidneys, and liver [54]. Pb has a half-life of several weeks in the circulatory system and nearly two years in ...
