Is ionisation enthalpy of potassium higher than that of sodium?
The ionisation enthalpy of potassium is lower than that of sodium.
Is isotopes have same ionisation enthalpy?
yes, it is correct.
Name the elements with highest ionisation enthalpy?
Helium
Would you expect the first ionisation enthalpy for two isotopes of the same element to be same or different?
This value is identical for isotopes.
Why oxygen have less ionisation enthalpy than fluorine?
Oxygen has a lower electronegativity than fluorine (3.5 as compared to 4).

How can you tell what kind of bonds an elements atoms have?
atoms having low Ionisation enthalpy and ones having high electronegativity form ionic bond
What charge does metallic ions have?
Due to low ionisation enthalpy, metals easily lose an electron and attain positive charge. eg. Na+, K+
What are the properties of elements that vary periodically with the atomic number?
The properties like electronegativity , ionisation energy , enthalpy changes vary periodically with atomic number.
Ionisation energy of noble gases?
noble gases have the maximum ionisation energy. helium has the highest ionisation energy
How does ionization enthalpy vary as you move across the periods vary from left to right?
in a period size decreases from left to right and hence electrons are more tightly held to the nucleus. so electron gain enthalpy increases across a period . down the period size increases and thus in general electron gain enthalpy decreses .
What is the enthalpy of HDPE?
enthalpy LDPE
