|---|---|---|---|---|---|
| Elements in the far left form what kind of ions? | show 🗑
|
||||
| Group 1 atoms generally lose ___ electron(s) to from ions with ___ positive charge. | show 🗑
|
||||
| show | Group 2 atoms generally lose 2 electrons to from ions with a positive charge of 2.
🗑
|
||||
| What type of ions does Group 18 form? | show 🗑
|
||||
| show | We refer to Group 18 elements as the "Noble Gases".
🗑
|
||||
| show | Group 17 elements often gain one electron to from a negative ion.
🗑
|
||||
| Then, if this pattern continues, what type of ions do elements in Group 16 like to form? | show 🗑
|
||||
| The atoms of Group __ and Group __ elements are the most reactive. | show 🗑
|
||||
| The atoms of what group are the least reactive? | show 🗑
|
||||
| Most elements are what? | show 🗑
|
||||
| Name 2 characteristic of metals. | show 🗑
|
||||
| show | Two characteristics of metals are that they have a shiny appearance and that they are usually solid at room temperature.
🗑
|
||||
| show | A couple of ways you can get info on an atom properties it that the atoms, or the atomic size gets larger top to bottom and decreases left to right. Also, density increases left to right.
🗑
|
||||
| Would you expect strontium to be more like potassium or like bromine? | show 🗑
|
||||
| Barium is in group 2. Recall that atoms in Group 1 lose 1 electron to form ions with a +1 charge. What type of ion would barium form? | show 🗑
|
||||
| show | The atomic number of Sulfur is 16 and Chlorine is 17. It is impossible to find an element that has an atomic number of 16.5 because there is no such thing as a half atom.
🗑
|
||||
| show | Metals are malleable meaning they can be shaped easily by pounding, bending, or being pulled into long wires.
🗑
|
||||
| show | Alloys can be stronger, less likely to corrode and easier to shape than pure metals.
🗑
|
||||
| show | Groups 3-12 are called transition metals because they are generally less reactive.
🗑
|
||||
| show | Nonmetals have properties opposite of metals.
🗑
|
||||
| show | Two characteristics of nonmetals are that they have a dull appearance and they are poor conductors of heat and electricity.
🗑
|
||||
| show | Two characteristics of nonmetals are that they are not malleable and most are gases at room temperature.
🗑
|
||||
| show | Nonmetals are found on the right of the table.
🗑
|
||||
| Where are metalloids found? | show 🗑
|
||||
| What are the three main classes of the Periodic table? | show 🗑
|
||||
| What are the main characteristics of metals? | show 🗑
|
||||
| Use the periodic table to determine whether a carbon atom or a Fluorine atom would be more reactive. | show 🗑
|
||||
| show | Noble gases are not very common in the Earth's atmosphere, and a lot of other elements are. Ex. Argon gas makes up 1% of the atmosphere while nitrogen makes up 78%. Scientists use the atmosphere to find the elements.
