What is nsu?
If you wanted a chemistry expert, why didn't you follow directions and type chemistry into the School Subject box?
Also you need to indicate what elements.
To determine the ionic charges expected for elements using only the periodic table, you need to refer to the main group elements. The main group elements, also known as the representative elements, are found in Groups 1, 2, and 13 to 18 of the periodic table. The ionic charge of an element can be determined by examining its group number.
Here is the expected ionic charge for each of these elements, using the format 1+ and 2-:
1+:
- Group 1 elements, known as alkali metals, have a single valence electron. They tend to lose this electron, resulting in a 1+ charge. For example, sodium (Na) is in Group 1 and is expected to have a 1+ charge (Na+).
2-:
- Group 16 elements, known as chalcogens, have six valence electrons. They tend to gain two electrons to achieve a stable 8-electron configuration, resulting in a 2- charge. For example, oxygen (O) is in Group 16 and is expected to have a 2- charge (O2-).
It is important to note that these charges are general patterns and may vary in certain compounds. Transition metals and inner transition metals, found in the d-block and f-block, have different and more varied ionic charges, which cannot be determined solely by their group numbers on the periodic table. Determining the charges of these elements typically requires additional information or knowledge about specific compounds.
