he put uranium crystal and photgraphic plate ina drawer
there was an ominouse spot on his photographic plate that of which was placed next to the plutonium crystal
If the "items" in question were photographic plates, then he noticed that they had been "fogged," which he determined was due to the presence of radioactive materials nearby.

I believe it was originally brought about by Isaac Newton, and later explained and backed up by Albert Einstein, who later proved the existence of atoms and molecules.
Scientists concluded that electrons occupy specific energy levels by exciting atoms of different elements with UV light and watching the light emitted as the electrons fall back to ground state. Different elements had different characteristic emissions each time.
what answers
My friend knows but sadly i dont I will tell you later
no, nuclear decay is a natural phenomena that has existed as long as the universe becquerel discovered it in the 1890s when he left uranium ore samples in a drawer on a stack of unexposed photographic plates and later when they were developed found that the ore had somehow exposed them.
Robert Hook was first to look through a microscope to observe slices of cork. He described these as "boxes", later came to know as "cells".
Becquerel discovered radioactivity by accident while studying a mineral containing uranium. he observed that with exposure to sunlight the mineral gave off a penetrating energy that exposed the film. while one day he tried the experiment one day the day was cloudy so he put it away in a dark desk drawer and at the next day he found the picture of the mineral and later found out that the mineral did not need sunlight to expose radiation so he gave it to two young researchers that eventually isolated the two elements named polonium and radium
Tesla did not make the Flourscent bulb. In 1859 Alexandre E. Becquerel did. Tesla wanted to make use of them and discussed them at length decades later. But he did not discover, or invent them.
yes u can == ==
To be able to study and observe it later and learn more about the past and the creatures in it.
It saves items that you might want later
maybe later
out of the remote control on the table
There is a battery in the toy truck. You can use the screwdriver from the kitchen drawer to take it out and put it in the TV remote. Then you can put it back later to use the truck.
No.
The word later is an adjective. It is the second of two items.
