Atomic number, atomic weight and charge of magnesium ion (Mg 2+) During the formation of a bond, magnesium donates two electrons of the last shell to form bonds and turns into a magnesium ion (Mg+2). In this case, the magnesium atom carries a positive charge. Mg – 2e – → Mg 2+

Exercise 15.4. 2 WebPrincipal Quantum Number (n) The principal quantum number n indicates the shell or energy level in which the electron is found. The value of n can be set between 1 to n, where n is the value of the outermost shell containing an electron. This quantum number can only be positive, non-zero, and integer values. That is, n=1,2,3,4,.. For example, an Iodine atom … miniクラブマン
