element X has an electron affinity of 295.3 kJ/mol and the following ionization energies (in kJ/mol): IE1 = 1.008e3, IE2 = 1.846e3, IE3 = 3.20e3. In what column of the periodic table is this element probably found?
Explain the trend in effective nuclear charge (Z*) going from left to right across periods in the periodic table and with reference to Z*, rationalise why the ionic radii of the following anions decrease in the order shown: As3- > Se2- > Br-.
Let's say we have an imaginary element y:
First ionization energy = 771 kJ/mol
Second ionization energy = 2121 kJ/mol
Third ionization energy = 3801 kJ/mol
Fourth ionization energy = 30,001 kJ/mol
which of the following statements is incorrect?
Y could belong to Group IIIA.
The last ionization energy is much greater than the third ionization energy because Y3+ consists of a noble-gas core.
Y could belong to group VA
The third ionization energy is greater than the second ionization energy because Z2+ has a bigger charge than Y+.
Y could belong to Group IIIB.

Typically, the ionization energy increases from left to right on the periodic table. However, there are minor irregularities. For example, the ionization of oxygen (Group 6A) is lower than nitrogen (Group 5A). Considering the electron configuration of these two atoms, choose the best explanation for this observation. A) After the loss of an electron, oxygen would have a stable noble gas configuration. lonization Energy (kJ/Mol) 3000 B) Oxygen has a smaller core charge, so the atom is more likely to give up an electron. 2500 2000 1500 C) The valence electron is in a 2p orbital 1000 500 rather than a 2s orbital. This is further from the nucleus and so it is not held as tightly.
