Detailed explanation-1: -Ionization is the process by which ions are formed by gain or loss of an electron from an atom or molecule. If an atom or molecule gains an electron, it becomes negatively charged (an anion), and if it loses an electron, it becomes positively charged (a cation).
Detailed explanation-2: -Answer and Explanation: The following statement is TRUE: (b) Ionization energy measures the energy absorbed when an electron goes from a ground state energy level to n = ā .
Detailed explanation-3: -The ionization energy is the quantity of energy that an isolated, gaseous atom in the ground electronic state must absorb to discharge an electron, resulting in a cation. H(g)āH+(g)+eā This energy is usually expressed in kJ/mol, or the amount of energy it takes for all the atoms in a mole to lose one electron each.
Detailed explanation-4: -Answer: c. There is a strong attraction between the electrons and the protons. If this first ionization energy is relatively high, then it implies that there is a strong attraction between the protons of the nucleus and the first electron that is to be removed.
