313358 Five ionization energy values in \(\mathrm{kJ} / \mathrm{mol}\) are listed below: \(\mathrm{E}_{1}=870, \mathrm{E}_{2}=830, \mathrm{E}_{3}=1010, \mathrm{E}_{4}=1290\),
\(\mathrm{E}_{5}=376\). These are

1 Successive ionization energies for the element with atomic number 5
2 The first I.E. of successive elements in group 15, 16, 17, 18 and 1 respectively
3 The first I.E. of elements with atomic number 1 to 5
4 Successive I.E. for transition elements with four electrons in d-subshell.

313359 Elements X, Y and Z have atomic numbers 19, 37 and 55 respectively. Which of the following statement is true about them?

1 Their ionization potential would increase with increasing atomic number
2 'Y' would have an ionisation potential between those of X and Z.
3 Z would have the highest ionisation potential
4 Y would have the highest ionisation potential

313360 The first ionisation energy of aluminium is slightly lower than that of magnesium because

1 Magnesium has a higher nuclear charge
2 The outer electron in aluminium is in a p-orbital and not in s-orbital
3 In aluminium, the electron is being lost from a doubly filled orbital
4 The radius of the aluminium atom is greater than the magnesium ion.
