True or False:

1. As the electronegativity of an atom increases, the first ionization energy generally increases.

2. The successive ionization energies (in a hypothetical unit) for an unknown element are IE1 = 200, IE2 = 300, IE3 = 425, IE4 = 2500. The possible identity of this element is B.

3. The first ionization energy of O is larger than the first ionization energy of N.

4. The removal of an electron from a neutral atom results in a release of energy in the form of heat.

1A. The periodic trend for ionization energy states that typically ionization energy increases to the [left, right] across a period.
Complete the following sentence by selecting the appropriate choices.1A. The periodic trend for ionization energy states that typically ionization energy increases to the [left, right] across a period. This is because as effective nuclear charge increases to the [right, left] across a period, the [valence electrons, core electrons] experience a stronger attraction to the [valence electrons, core electrons, nucleus] and therefore require more energy to be removed.Complete the following statement for magnesium and aluminum.1B. Contrary to the periodic trend, the...
