How would you make an isotope for one of your models? What would change with the model?
Deuterium is a hydrogen isotope. A normal hydrogen atom has 1 electron and 1 proton. In order to make the deuterium isotope for hydrogen a neutron must be added. So the deuterium isotope would contain 1 neutron, 1 proton and 1 electron.
For one of your models, show with another image what happens when energy excites an electron.
Once the electron is excited, what do we typically observe when the electron returns to the ground-state?
When an electron is excited it goes to a higher energy levels state and when it returns to a lower energy state it emits a photon of energy. The photon may be observes as light.
Why are some elements different colors when they are excited?
Different elements emit different colors. The color of the excited elements depends on what the element is and what it is made up of. Different elements are used in fireworks to make them different colors.
Do a little research to list which elements are used to make the different colors of fireworks.
Aluminum is used to make silver and white flames and sparks. It is commonly found in sparklers.
Barium is used to create green colors. This element also helps stabilize other volatile elements found in fireworks.
Calcium salts are used to make orange fireworks. It also deepens other firework colors.
Antimony is used to create glitter effects.
Carbon is used to fuel fireworks.
Copper is used to produce blue colors.
Lithium is used to make a red color. Lithium is commonly used as a colorant in many fireworks.
Magnesium creates a very bright white color in fireworks.
Explain the overall organizational structure of the periodic table.
The periodic table is arranged so elements with similar properties are grouped near each other. The far left side of the periodic table is the alkali metals group (the top left is where the first atomic number starts) and the far right side of the periodic table is the noble gas group (the bottom right is where the last atomic number is located). Each element within the table has its own atomic number (number of protons in the nucleus) and its own mass number (the sum of protons and neutrons within the nucleus). The atomic number is listed across (horizontally-left to right) the table.
List two example elements for each of these groups or classes:
Alkali Metals: Potassium & Sodium
Alkaline Earth: Magnesium & Calcium
Halogens: Chlorine & Iodine
Noble Gases: Neon & Argon
Transition Metals: Nickel & Copper
Non-Metals: Sulfur & Carbon
Metalloids: Silicone & Arsenic
Considering the overall volume of your element models, what makes up most of the volume of an atom?
It seems as though empty space takes up the most volume. However, if I must name a subatomic particle that takes up the most volume it would be electrons. Electrons spread out while the protons and neutrons are closer to each other.
