Yes, platinum can combine with other elements to form various compounds. It is a versatile metal that can form chemical bonds with elements like carbon, oxygen, and sulfur to create different types of complexes and compounds.
dont know and dont care
Mendeleev managed to predict undiscovered elements by comparing two different elements atomic mass, that had a gap between them, and averaging there atomic mass for example: Mn _ Co if you dont know what the middle element is then by looking at the the atomic mass of Mn and Co you can work out roughly what its atomic mass is. Mn=55 and Co=59 so by adding them together and dividing by 2 you get 57 however Fe is in fact 56 but as you can see it was very close and this was how he would work out the atomic mass. He would also compare the properties of elements with similar atomic mass for example the alkaline metals such as lithium and sodium will react in the same way by doing this he could work out what a missing element would look, feel, react like etc.
i dont same Q ive been lookin 4
Mendeleev arranged the elements in a table ordered by atomic mass, corresponding to relative molar mass as defined today. Mendeleev predicted the discovery of other elements and left space for these new elements, namely eka-silicon (germanium), eka-aluminium (gallium), and eka-boron (scandium). Thus, there was no disturbance in the periodic table.
Yes. The satellites see everything bigger than a license plate.
Xrays would have not been invented but i dont know bout the rest Xrays would have not been invented but i dont know bout the rest
We really dont know. It was discovered by whoever was living at that time. Could have been caveman. caveman lived on earth.. and i dont think they would be so smart to actually know what they're standing on LOL
It is a wind instrument, that has been around for centuries. probably only introduced into an orchestra in the late baroque period or early classical period
dont no its a rubbish question
i dont now
i dont know i dont think anybody does
Which ever year people discovered that they could move around and float in water.
i dont know whow discovered it ?
Calcium was discovered by Sir Humphry Davy in 1808 through the process of electrolysis. He isolated calcium metal by passing an electric current through molten calcium chloride. This discovery helped in understanding the nature of elements and their properties.
i dont noi dont noi dont nou smell
