F is a group 17 element which are referred to as halogens. hence requires one electrons to obtain octet electron configuration.Therefore F has -1 charge. Xe is a group 18 element which are referred to as noble gas which has octet electron configuration but due to the two F- Xe has +2 formal charges.
Answer:
H2
Explanation:
In the first place it is necessary to consider that these two elements will be their diatomic form initially, that is, H2 and N2.
first we should check the equilibrium constant Kp tables in this case at a temperature of 3000K
Value for dissociation reaction of H2 in Kp = -3.685
Value for dissociation reaction of N2 in Kp = -22.359
Equilibrium constant for H2 dissociation is higher than N2 dissociation. so for this comparation H2 is more likely to dissociate.
Answer:
Periodic Law.
Explanation:
The Periodic Law states that the physical and chemical properties of the elements repeat in a systematic and predictable way when the elements are arranged in order of increasing atomic number.
Many of the properties are repeated at intervals.
When the elements are arranged correctly, the trends in element properties become apparent and can be used to make predictions about unknown or unfamiliar elements, simply based on their placement on the table.

While all </span>atoms<span> of an element were identical, different elements had </span>atoms<span> of differing size and mass. Hope this answers the question. Have a nice day.</span>
