In this lab you observed that each element emits a unique color of light when heated in a flame. if these light emissions were examined through a prism, you would observe that the emitted light is actually composed of different wavelengths of light that may lie in the violet region, the green region, or the red region of the visible spectrum. each element has a unique emission spectrum. look up the emission spectra for the element tested in this lab. do research on how scientists apply these emission spectra to investigate the chemical composition pf stars. for example what is the emission spectrum of the sun, and what does this spectrum reveal about the types of elements in the sun

The sun's emission spectrum contains most of the visible spectrum, and it also contains UV light and infrared radiation. The colour depends on the atom, like oxygen, which can be found in the sun, is responsible for the colours red and green.

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.

a electronegativity decreases beacuse the size of nucleus is bigger.
