Question

The first ionization energies of five consecutive elements in the periodic table with atomic numbers Z, Z+1, Z+2, Z+3 and Z+4 are given below. Z is less than 16 and one of these elements is a metal. The ionization energy values are not given in any particular order. Ionization Energies: Energies: 495, 1313, 1681, 2081, 1402 kJ mol-¹​

Answer 1

Z: 495

Z+1: 1313

Z+2: 1402

Z+3: 1681

Z+4: 2081

Step-by-step explanation:

The attached shows that ionization energy increases up and to the right. If we have five consecutive elements then that means as we increase the atomic number we are moving to the right and therefore increasing ionization energy.
