Two sets of ionizations are shown in the tables below. Complete the tables by ordering each set of ionizations by increasing amount of energy required. In other words, for each set choose "1" next to the ionization that would require the least energy, "2" next to the ionization that would require the next least energy, and so on. F-> F+ + e- He-> He+ + e- As-> As+ + e- ---------------------------- Ra-> Ra+ + e- He-> He+ + e- Sr-> Sr+ + e-

Which of the following statements are correct? o It takes a larger amount of energy to ionize a neutral, isolated, atom of an element with a ns?np? valence shell than to ionize an a neutral, isolated, atom of an element with a ns?np3 valence shell. The second ionization energy of an element with an ns' valence shell is smaller than the second ionization energy of an element with an ns? valence shell. The size of a cation is always smaller than the size of the corresponding neutral atom. The energy of a halogen atom in the gas state is smaller in magnitude than the energy of the corresponding halide anion in the gas state.

Rank the following elements by electron affinity, from most positive to most negative EA value. Iodine, Neon, Sulfer, Arsenic, Sodium.

The energy needed to remove an electron is called ionization energy. Which of the statements are true of ionization energy and its trends found in the periodic table? increases going down a column (top to bottom) decreases going down a column (top to bottom) increases going across a row (left to right) decreases going across a row (left to right)
