This looks like chemistry to me. What kind of School Subject I Nsu? Is that even a word? I can't find it in the dictionary.
To determine the ionic charge of an element based on the periodic table, you need to consider the element's position and group number. The group number refers to the column in which the element is located.
For elements in Group 1 (also known as the alkali metals), such as lithium (Li), sodium (Na), and potassium (K), the expected ionic charge is 1+. This is because these elements readily lose one electron to achieve a stable configuration and form a positively charged ion.
For elements in Group 2 (also known as the alkaline earth metals), such as beryllium (Be), magnesium (Mg), and calcium (Ca), the expected ionic charge is 2+. These elements lose two electrons to achieve a stable configuration and form a positively charged ion.
It's important to note that the ionic charge of an element may vary depending on the specific chemical reaction or compound it is involved in. But in general, elements within these groups tend to exhibit these common ionic charges based on their electron configurations.
