Hydrogen, oxygen and iron are some of the most common elements you can find around. So what are elements?
An element is a matter that cannot be resolved anymore into simpler substances
by ordinary heat, light, electricity, or any attack by other substances. It
also cannot be decomposed. So according to that ‘rule’, elements
can never be broken down. However, if millions of times more energy than ordinary
energy created by special equipment can actually break them down.
In ancient times, elements were believed to be fundamental substances. However, scientists have found that elements actually consists of some elementary particles.
There are many different types of elements. Ninety of the elements are natural,
but however, twenty-two more elements have been artificially made. Although
there are only 112 types of elements, the millions and millions of objects around
us are made out of them.
Abbreviating the names of elements is often convenient and widely used. For
each element, a particular symbol has been chosen that consists of one or two
letters. The symbols are derived from the names of the elements. For example,
H stands for hydrogen, He for helium, C for carbon, and so on. The abbreviations
however, are not always derived from the English names, but symbol Fe for iron
comes from the Latin word ‘ferrum’, and W for tungsten comes from
the German word ‘wolfram’. These symbols are internationally recognized
and are used even by people whose native languages do not use the Roman alphabet,
such as the Russians and the Japanese.
Atoms of the element germanium (Ge) can be seen in this computerized image made by a scanning tunnel microscope. The microscope maps the atom surface by detecting an electric current flowing from the surface to the point of a fine metal probe.
After reading the above things, if you find it relevent, you can carry on reading.
