This is one of John Dalton's four postulates in his Modern Atomic Theory of Matter.
Einsteinium is the element named after the scientist Albert Einstein. It is a synthetic element with the atomic number 99.
The element was discovered by (insert name of scientist or researcher).
einsteinium (atomic number 99) was the element named after the scientist that created e=mc2 or Albert Einstein.
Element
The first element, hydrogen, was discovered in 1766 by English scientist Henry Cavendish through the reaction of metals with acids, producing a gas that he called "inflammable air." This gas was later recognized as hydrogen by another scientist, Antoine Lavoisier, in 1783.
atoms are of an element are the same becasue the are all made from identical particles. there is no way to distinguish one electron from another electron. the same is true for neutrons and protons. so by virtue of the fact that its constituents are identical, all atoms of the same element are identical.
Each atom of an isotope of beryllium (or of another element) is different from the atoms of an other isotope. But all the atoms of an isotope are identical.
They are identical.
Yes, an element is composed of millions of identical atoms.
an element
The number of electrons in isotopes is identical.
Einsteinium is the element named after the scientist Albert Einstein. It is a synthetic element with the atomic number 99.
Because the existence of isotopes was discovered not all atoms of an element are identical.
A scientist can find an element with properties similar to another by looking at elements in the same group or column of the periodic table. Elements in the same group tend to have similar chemical properties due to their similar outer electron configurations. This allows scientists to predict the behavior of an element based on its position on the periodic table.
