What is a best explanation for different metals having various colors? es
A)
The spectrum of lines will be produced, some of which will be in the
visible part of the spectrum. The color you see will be the highest energy
observed.
B)
The spectrum of lines will be produced, all of which will be in the visible
part of the spectrum. The color you see will be the most common color in
the spectrum.
The spectrum of lines will be produced, all of which will be in the visible
part of the spectrum. The color you see will be a combination of all these
individual colors.
D)
The spectrum of lines will be produced, some of which will be in the
visible part of the spectrum. The color you see will be a combination of all
these individual colors.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

answer///carbon;

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
