Question

Which of the following is not the correct order for the stated
property ?
(a) Ba > Sr > Mg; atomic radius
(b) F > O > N : first ionization enthalpy
(c) Cl > F > I; electron affinity
(d) O > Se > Te; electronegativity

Answer 1

Answer:

first order is not correct

Ba >Sr>Mg, atomic radius

Answer 2

F > O > N : first ionization enthalpy is the statement not correct.

Explanation:

• The energy need an electron to remove from ion and gaseous atom.
• Ei of the molecule is the initial ionization energy which need to remove mole of electrons to mole of ions.
• Ionization energy is higher, then removing an electron is more difficult.
• It is very important due to chemical bonds strength can be predicted.
• In periodic table, ionization with ionic and atomic radius, electron affinity, metallicity, electronegativity are the trends.
• In electronic configuration, there is a half-filled shell in the N and an electron should be removed from it. Hence, in first ionization energy oxygen is greater than nitrogen.
