11) The laser in a laboratory in the physics department at UNC emits visible light with a frequency (v) of 4.9 x 1014 s-1.
(a) What is the wavelength (m) of this light?
(b) What is the energy of this light?
(C) What color might this wavelength of visible light be?

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

1.solid

2.carbon dioxide
