Why is enthalpy change of atomization of bromine is higher than bond enthalpy?

because u need to dissconnect the inter-molecular bonds aswell.(it's natural state is liquid)
not only the covalent ones.

What is the sign of the enthalpy change for an endothermic reaction?
Endothermic reaction: In an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings by the reaction therefore enthalpy change show positive sign in a endothermic reaction..
Which enthalpy is higher 2 Cl or cl2?
2Cl
Why does bromine have higher ionization energy then lead?
Bromine has less valence shells than lead making the distance between its valence electron and its nucleus less than that of lead. This means that there is greater attraction between the nucleus and electron for bromine and it requires a higher ionisation energy to remove its electron.
In an exothermic reaction is the energy of the products higher or lower than that of the reactants?
In an exothermic reaction the energy of the products is less than that of the reactants.
What is the relationship between the enthalpy h and entropy s of a reaction that is spontaneous at higher temperatures but not at lower temperatures?
-H, +S
What is the sign of the enthalpy change for an endothermic reaction?

Which has higher electron affinity Iodine or bromine?
Bromine has a higher electron affinity.
Is ionisation enthalpy of potassium higher than that of sodium?
The ionisation enthalpy of potassium is lower than that of sodium.
Which enthalpy is higher 2 Cl or cl2?
2Cl
Why does bromine have a higher ionization energy than selenium?
Bromine has the highest.
Which has a higher atomic raduis chlorine or bromine?
Bromine has a larger radius (not raduis) than chlorine.
How do you know if an enthalpy change diagram is endothermic or exothermic?
If you plot the reaction coordinate (what I think you mean by "enthalpy change diagram"), the reaction will be exothermic if the products are lower on the graph than the reactants. If they are higher than it is endothermic. For instance, if you go to the linked Wikipedia page (link to the left of this answer), the graph shown is of an exothermic reaction.
Why is enthalpy of chemisorption higher than physisorption?
Chemical bonds in chemisorption are much stronger.
Does potassium or bromine have a higher ionization energy?
Bromine has because the ionization energy increases as you move across and decreases as you move down.
How does melting point of bromine change with external pressure?
Bromine, as many other materials gets a higher melting point when pressure is low [less energy is needed to set molecules free] and lower melting point when pressure is high [more energy needed].
Why does bromine have higher ionization energy then lead?
Bromine has less valence shells than lead making the distance between its valence electron and its nucleus less than that of lead. This means that there is greater attraction between the nucleus and electron for bromine and it requires a higher ionisation energy to remove its electron.
Why does a aqueous solution of iodine not react with sodium bromide?
Bromine is more reactive than iodine/bromine is higher in the activity series than iodine
