Concept explainers
(a)
Interpretation:
True and false
Ionization energy is the energy required to remove the most loosely held electron from an atom in the gas phase.
Concept Introduction:
In chemistry, the energy which is needed to eliminate an electron from an isolated molecule or atom is known as ionization energy which is also known as ionization potential.
(b)
Interpretation:
When an atom loses an electron, it becomes a positively charged ion.
Concept Introduction:
Atoms contain same number of protons and electrons and they are neutral in nature. An electrically charged particle that is ion produced by either adding electrons to a neutral atom results a negative ion or removing electrons from a neutral atom results a positive ion.
(c)
Interpretation:
Ionization energy is a periodic property because ground state electron configuration is a periodic property.
Concept Introduction:
The energy required to remove the most loosely held electron from an atom in the gas phase is known as ionization energy.
(d)
Interpretation:
Ionization energy generally increases going from left to right across a period of the periodic table.
Concept Introduction:
The energy required to remove the most loosely held electron from an atom in the gas phase is known as ionization energy.
(e)
Interpretation:
Ionization energy generally increases in going from top to bottom within a column in the periodic table.
Concept Introduction:
The energy required to remove the most loosely held electron from an atom in the gas phase is known as ionization energy.
(f)
Interpretation:
The sign of ionization energy is always positive, the process is always endothermic.
Concept Introduction:
The energy required to remove the most loosely held electron from an atom in the gas phase is known as ionization energy.
