You can identify elements by their unique atomic number, and compounds by their chemical formulas.
20. Can you always determine what the element is by the number of electrons? Yes, you can determine the element by the number of electrons, as long as you know the atomic number of the element. The atomic number uniquely identifies each element, and it corresponds to the number of electrons in a neutral atom of that element.
21. How do you find the identity element of a group? The identity element of a group, in abstract algebra, is an element that, when combined with any other element in the group, leaves that element unchanged. It is typically denoted as “e” or “1.” The identity element can be found by examining the group’s operation (e.g., addition or multiplication) and identifying which element behaves as the identity element.
