Rank from largest to smallest atomic radius. To rank items as equivalent, overlap them.
O, S, Se, Po, Te
O < S < Se < Te < Po
To rank the elements from largest to smallest atomic radius, we need to consider their positions in the periodic table. The general trend is that atomic radius tends to increase as we move down a group (vertical column) and decrease as we move across a period (horizontal row).
Let's analyze each of the given elements:
1. Oxygen (O): Oxygen is located in Group 16 (also known as the "oxygen group") and Period 2 of the periodic table. Oxygen is towards the right-hand side of the periodic table, so it has a smaller atomic radius compared to the other elements.
2. Sulfur (S): Sulfur is also in Group 16 and Period 3. It is one row below oxygen, so it has a slightly larger atomic radius than oxygen.
3. Selenium (Se): Selenium is in Group 16 and Period 4. Again, it is one row below sulfur, so its atomic radius is larger than both oxygen and sulfur.
4. Polonium (Po): Polonium is in Group 16 and Period 6. It is two rows below oxygen and sulfur, so it has a significantly larger atomic radius compared to the first three elements.
5. Tellurium (Te): Tellurium is in Group 16 and Period 5. It is one row above polonium, so its atomic radius is smaller than polonium but larger than the first three elements.
Based on this analysis, we can rank the elements from largest to smallest atomic radius as follows:
Po > Te > Se > S > O
To summarize, the atomic radii of the elements, from largest to smallest, are: Polonium, Tellurium, Selenium, Sulfur, Oxygen.
To rank the elements in order of largest to smallest atomic radius, we need to compare the atomic sizes of each one.
The atomic radius generally increases as we move down a group in the periodic table and decreases as we move across a period from left to right.
Based on this information, let's rank the elements:
1. Po
2. Te, Se
3. S
4. O
Polonium (Po) has the largest atomic radius since it is located at the bottom of the group, while oxygen (O) has the smallest atomic radius as it is located at the top right corner of the periodic table.
Since sulfur (S) is in the same group as oxygen, their atomic radii are similar. Similarly, selenium (Se) and tellurium (Te) are in the same group and thus can be considered equivalent.
Therefore, the ranking from largest to smallest atomic radius would be: Po > Te, Se > S > O.
