K- pale violet
Rb and Cs- violet

These flame color show that when we moved from down the group, the wavelength decreases (frequency increases).
As the color of Li is red that shows ,it has less emission energy as compare to Rb and Cs that have color violet (more emission energy).

Carbon is important to the structure of macromolecules because it has a valence of 4. what does this mean?

gogolik [260]

The valence part is referring to the outer most ring of electrons. Carbon only has four on the 'valence' or outer most ring helping it to form bonds with other things. I hope this helps!! Good Luck!!! :)
