The energy required to remove an electron from a neutral isolated gaseous atom and convert it into a positively charged gaseous ion is called ____________. (electron affinity, ionization potential,
electronegativity)
Choose the correct answer from the options given below:
Ionisation potential increases over a period from left to right because of the
(A) Atomic radius increases and nuclear charge increases
(B) Atomic radius decreases and nuclear charge decreases
(C) Atomic radius increases and nuclear charge decreases
(D) Atomic radius decreases and nuclear charge increases
Give reason for the following:
Ionisation potential of the element increases across a period.
A, B, C are three elements in which B is an inert gas other than helium.With this information complete the following table.
| Element | Atomic number | No. of electrons in the valence shell | Group to which the element belongs |
| A | Z - 1 | ||
| B | Z | ||
| C | Z + 1 |
Also, explain the following : Ionization energy of element C is less than that of element A.
In a group, a particular element has the lowest ionization potential; does it ionize most easily or least easily? Explain with example.
Arrange the following as per the instruction given in the bracket
Na,Li,K (Increasing ionization energy)
Arrange the following as per the instruction given in the bracket:
Potassium, Lithium, Sodium (increasing order of ionization potential).
First ionisation enthalpy of two elements X and Y are 500 kJ mol−1 and 375 kJ mol−1 respectively. Comment about their relative position in a group as well as in a period.
Arrange the following in order of increasing ionisation energy:
F, O, Ne
Explain your choice.
Give reason:
Ionisation potential of the element increases across a period from left to right.
