|
||||
| show | -Baisically, an atom describes an element, for example Boron-A compound is made up of more then one element (H2O for example)-
🗑
|
||||
| How many elements are there? Where are elements listed? | show 🗑
|
||||
| Are all elements found on earth?If not, explain where they can be found. | show 🗑
|
||||
| show | -On top, it says the ATOMIC NUMBER-equals the number of protons (which equals the amount of electrons in a 0 charged atom)-On the bottom, it show the ATOMIC MASS-equals the protons + the neutrons-neutrons = atomic mass - atomic number
🗑
|
||||
| What does adding/taking away a proton in the atom change about the atom? Adding or taking away an electron? Adding or taking away a neutron? | show 🗑
|
||||
| Why is the atomic number of an element never a whole number? | show 🗑
|
||||
| show | -In the first shell the max electrons:2-In the 2nd, the max is 8-In the 3rd, the max is 32 BUT once there's 8 electrons in it it goes on to the next shell -The max for all the other shells is 32.
🗑
|
||||
| Why do atoms lose or gain electrons? What is the octet rule? | show 🗑
|
||||
| What is an exeption to the rule? Why is that exception still chemically stable? | show 🗑
|
||||
| What do Lewis structures tell you about valence electrons? How do Lewis structures help you to know what an atom has to do to become stable? | show 🗑
|
||||
| Explain what contributions Mendeleev and Moseley made to the organization of the periodic table. | show 🗑
|
||||
| show | -The word "periodic" means in a regular, repeated order.
-That's what the periodic table is in.
🗑
|
||||
| List at least seven different patterns that you learned about how the periodic table is organized. | show 🗑

🗑
|
||||
| What does the group number tell you about valence electrons? | show 🗑
|
||||
| show | -Transition Metals: all non reactive, and will tarnish over time. They're mailable
-Alkali Metals: Going down the list, it gets easier to cut them, and their melting point decreases. They all like to react with CI. They burn colorfully when in salt form.
🗑
|
||||
| show | They're all non metals and they all change states. They're all poise nous alone, but not when combines with other compounds. All of them are colors, and they get more reactive as you go down the list. They're all used for a lot of everyday things.
🗑
|
||||
| What are the differences between the characteristics of metals and non metals? | show 🗑
|
||||
| Which elements are metals, non metals and metalloids? | show 🗑
|
||||
| show | -The most reactive metals are the alkali metals
🗑

|
||||
| Which element has a Lewis Structure that is different from the other elements in it's family? Why? | show 🗑
|
||||
| Based on the Lewis Dot Structures for each family, what type of ion does each family form? | show 🗑
|
||||
| How does our study of elements relate to the formation of the universe? How long did it take for elements to form? Why? Which were the first elements to form? Why? How did other elements form? | show 🗑
