Many social scientists and historians believe that before a national mass movement can succeed requires one essential element. That concerns the powers or the government that is seen as the establishment. If the current power structure is discredited, that is one key for the success of a mass movement.
Hydrogen .
scientists believe that it had 118 protons but no one can be sure until all info is found
He is out of his element. The scientists have isolated a new element.
what element is used and why do scientist chose it
The element required for an iron kettle to rust is oxygen.
scientists knew that oxygen was a element as it had the atoms of only O i,e. oxygen and helped in increase in combustion
Burning is the rapid Oxidation of a Compound. Therefore the Element Oxygen is required.
Scientists no longer believe in Dalton's idea that atoms are indivisible and are the smallest particles of matter because further research has shown that atoms can be broken down into even smaller subatomic particles like protons, neutrons, and electrons. Additionally, Dalton's notion that all atoms of the same element are identical has been revised with the discovery of isotopes, which are atoms of the same element with different numbers of neutrons.
I don't believe "element" has an antonym.
atom. Each element has a unique number of protons in its nucleus, which determines its atomic number. By analyzing the atomic number, scientists can determine the identity of an element.
The element with atomic number 117 is Ununseptium (Uus). It has been observed but not officially recognised. It still has it's systematic IUPAC placeholder name as a result. Scientists believe that it will either be a metalloid or a halogen.
scientists are saying that element 112, currently called ununbium, will be similar to mercury.
