Detailed explanation-1: -Answer and Explanation: The statement is true .
Detailed explanation-2: -True: this is the ionisation energy. 2. After the atom is ionised, it then requires more energy to remove a second electron because the second electron is nearer the nucleus. True: When two charged particles interact the force they experience depends on the size of their charges, and their separation.
Detailed explanation-3: -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 = ∞ .
Detailed explanation-4: -Which of the following is true of the ionization energy of the elements? Ionization energy generally increases as we move left to right and increases as we move top to bottom in the periodic table.
Detailed explanation-5: -Solution: Identify the incorrect order of first ionization energy is Be<B<C. The sequence of Be, B, and C’s ionization potentials is Be<B<C is false. Because the effective nuclear charge grows with time, causing an increase in the ionization potential from left to right.
