cava chem 303 s1 3.03 Trends in the Periodic Table
| Question | Answer |
|---|---|
| Metals are to the [...] of the BAt line. | Metals are to the left of the BAt line. |
| Non-metals are to the [...] of the BAt line. | Non-metals are to the right of the BAt line. |
| Metalloids (metal-like elements) are [...] the BAt line. | Metalloids (metal-like elements) are on the BAt line. |
| The BAt line is the [...] line from Boron (B) to Astatine (At) | The BAt line is the imaginary line from Boron (B) to Astatine (At) |
| The upper right corner of the periodic table is what we’ll call the [...] Corner | The upper right corner of the periodic table is what we’ll call the New York Corner |
| The lower left corner of the periodic table is what we’ll call the [...] Corner. | The lower left corner of the periodic table is what we’ll call the LA Corner. |
| The closer an element is to the LA Corner, the [-er] the atomic radius. | The closer an element is to the LA Corner, the bigger the atomic radius. |
| The closer an element is to the New York Corner, the [-er] the atomic radius. | The closer an element is to the New York Corner, the smaller the atomic radius. |
| Rows of the periodic table are called ‘[...]’. | Rows of the periodic table are called ‘periods’. |
| [...] within the periodic table are called ‘groups’ or ‘families’ | Columns within the periodic table are called ‘groups’ or ‘families’ |
| Rows are [...] (you sit in them) | Rows are side-to-side (you sit in them) |
| Columns are [...] (they hold up buildings) | Columns are up-and-down (they hold up buildings) |
| [...] energy is how much energy it takes to tear away an electron from an atom. | Ionization energy is how much energy it takes to tear away an electron from an atom. |
| Ionization energy is [-er] near the New York corner and [-er] near the LA Corner. | Ionization energy is higher near the New York corner and lower near the LA Corner. |
| Cations are ions with a [...] charge. | Cations are ions with a positive charge. |
| Anions are ions with a [...] charge. | Anions are ions with a negative charge. |
| Ionic radii follow the same trend as atomic radii; big near [...], small near [...]. | Ionic radii follow the same trend as atomic radii; big near LA, small near NY. |
| Moving to the right across a period moves you closer to the [...] corner. | Moving to the right across a period moves you closer to the NY corner. |
| Moving to the bottom along a column moves you closer to the [...] corner. | Moving to the bottom along a column moves you closer to the LA corner. |
| Moving to the left across a period gets you closer to the [...] corner. | Moving to the left across a period gets you closer to the LA corner. |
| Moving to the top along a column moves you closer to the [...] Corner. | Moving to the top along a column moves you closer to the NY Corner. |
| Any movement up, down, left, or right across the periodic table can be translated to a movement towards one of the special [...] and away from the other. | Any movement up, down, left, or right across the periodic table can be translated to a movement towards one of the special corners and away from the other. |
| Cations are always [-er] than their elemental (atomic) forms, and anions are always [-er]. | Cations are always smaller than their elemental forms, and anions are always larger. |
| Electronegativity is the ability of an atom to attract new [-s] or hold on to its own [-s]. | Electronegativity is the ability of an atom to attract new electrons or hold on to its own electrons. |
| [...] is what creates ionization energy. It’s harder to take an electron away from something that holds on to it strongly! | Electronegativity is what creates ionization energy. It’s harder to take an electron away from something that holds on to it strongly! |
| Because electronegativity creates [...] energy, the trend for electronegativity and [...] energy are the same; stronger near the NY corner, weaker near the LA corner. | Because electronegativity creates ionization energy, the trend for electronegativity and ionization energy are the same; stronger near the NY corner, weaker near the LA corner. |
| The trends aren’t perfect: [...] has the highest electronegativity (not Ne or He) | The trends aren’t perfect: Flourine (F) has the highest electronegativity (not Ne or He) |
| Non-metals are [...] metals; they are [...] a kind of metal! | Non-metals are NOT metals; they are NOT a kind of metal! |
| non- = [...] | non- = NOT |
