Atoms can be divided more so thats not true. atoms from the same element arent all nesacarly identical because of isotopes
Answer:
1) False 2) True 3) True 4) False 5) True
Explanation:
1) Platinum metal is corrosion resistant because of its less reactivity due to high ionization energy.
2) The intermediate layer of platinum group metals, are extremely dense because their crystal structures are close-packed and these atoms tend to offer numerous d electrons in a metallic bond, resulting in highly efficient packing of relatively heavy metal ions in the bulk metal.
3) The extremely high bond strengths of the PGMs result in very low thermal expansion coefficients and extremely high elastic moduli.
4) Platinum came at number 10 in metals according to its electric conductivity property. There are other metals with different valence state that have high electric conductivity than platinum.
5) PGM's occurs at the concentration of 0.005 ppm in the earth's crust, resulting in extremely high prices and the price was 32 $ per gram in 2020.
There are more oxygen atoms in the reactants while there are less oxygen atoms in the product.
Both sides of the equation is supposed to be balanced for a balanced equation. If any one of them isn't balanced, the equation remains unbalanced.
The main reason why the reaction above can not be balanced is:
This chemical reaction SO2 + H2O -> H2SO2 is not correctly written.
It must be: SO2 + H2O -> H2SO3

Wavelength have an indirect relationship with frequency. Since gamma rays have the shortest wavelength, then they have the highest frequency. As the wavelength shortens, the frequency heightens.
Radio waves for example, have the longest wavelength, so it is expected that they have lowest frequencies.
