The English scientist John Dalton were one of the early scientists who paved the way to science, particularly in atomic chemistry. His atomic theory jumpstarted further developments made by J.J Thomson, Rutherford, Bohr, Schrodinger and many more.
Dalton's atomic theory can be summarized in 5 key points:
1. Atoms are tiny, indivisible and indestructible particles of an element.
2. Atoms of different elements vary in size and mass.
3. Atoms of an element are uniform in size and mass.
4. Compounds are formulated by a fixed ratio of individual atoms of elements.
5. Reactions undergo by rearranging the atoms of the reactants to form the products.
From the choices, the acceptable answer would be: <span>The ratio of atoms in a compound is fixed. </span>
The answer is d: <span>light waves you can see and waves of both higher and lower energy radiation.
The electromagnetic spectrum is the spectrum of all frequencies of electromagnetic (or light) radiation. The visible spectrum is a small range of these frequencies.</span>
The metals are elements which have low ionization potential and can lose electrons easily
the other physical characteristics associated with them and hence with Aluminium are
a) they can conduct electricity in molten state, hence It would only conduct electricity if it were melted.
b) It could be stretched into a thin wire. It means it is ductile.
In case of given aluminium metal the correct answer is
it could be stretched to thin wire
