Important questions about the atom [] [] 1. What are the three major components (parts) of an atom and where are they found? Include a visual.

 The main three parts of an atom are, positively charged protons, neutral neutrons in the nucleus, and negativly charged electrons in the electron shells surrounding the nucleus

2. What is true of most of the space inside an atom? Answer: Most space inside an atom is empty. 3. What is characteristically different from one atomic element to another (like helium and oxygen)? The fact that each element has a different atomic number. For example, the atomic number of helium is 2, while the atomic number of oxygen is 8. Both varying by only six protons and electrons. 4. Explain the difference between atomic number and atomic mass. Use a visual to explain the difference. Atomic number is the number of protons found in the nucleus of an atom. Atomic mass is the mass of a specific isotope. Its the total mass of protons, neutrons, and electrons in a single atom. 5. Compare the relative masses of the three subatomic particles and their charges. Create a data table.

6. What is an isotope? Visually show two isotopes and explain how they are similar and different from each other.
 * Particles || Mass || Charge ||
 * Proton || 1.6726 X10 -24g || Positive charge ||
 * Neutron || 1.675 X 10-24g || No charge ||
 * Electron || 9.108 X 10-28g || Negative charge ||

Isotopes are atoms that contain the same number of protons but a different number of neutrons. For example, chlorine 35 (35 in molar mass*) and chlorine 37 (37 in molar mass*) which means that the number of neutrons is different since chlorine 37 has a higher molar mass there is more neutrons. *molar mass is 6.02x1023  7. What happens when matter is heated?

Answer: When matter is heated, matter expands

8. What happens when white light passes through a prism? From a physics perspective, how are colors of light different from one another? Include a visual. 9. What are atomic line spectra? Where do they come from? Include visuals of line spectra of at least two different elements. An atomic line spectra is an emission line that is formed when an electron makes a transition from a praticular energy level of an atom to a lower energy state, taking away a photon of a particular energy and wavelength. The atomic line spectra or emmision sprecta is created from tin gasses in which atoms do not expierence many collisions.
