Answer: What are the numbers of valence electrons for each atom?
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
The cations and anions combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral ionic compound.
The oxidation states are known by their ability to gain or lose electrons which is decided by the number of valence electrons.
answer: all the colours except from blue would appear black as the wavelengths that correspond to these colours have been absorbed by the filter. The blue part of the rainbow would appear blue as the blue light is reflected back into your eyes and not absorbed by the filter.
Next come organisms that eat the autotrophs; these organisms are called herbivores or primary consumers -- an example is a rabbit that eats grass. The next link in the chain is animals that eat herbivores - these are called secondary consumers -- an example is a snake that eat rabbits.
