The properties of two elements are listed below. element atomic radius (pm) ionic radius (pm) first ionization energy (kj/mol) electron affinity (kj/mol) electronegativity br 114 195 1140 –325 3.0 k 243 152.2 418.8 –48.4 0.82 which prediction is supported by the information in the table? k will give up an electron more easily than br. both k and br will have the same pull on electrons. k will have a smaller size in comparison to br. both k and br will produce ions of the same size.

K will give up an electron more easily than Br.

Explanation:

Electronegativity of an element is a property that combines the ability of its atom to lose and gain electrons.

The lower the electronegativity value, the more electropositive an element is and the more readily it loses electrons.

From the data given, we see that Br has an E.N value of 3.0 and K has an E.N value of 0.82.

Therefore, Br is highly electronegative and it is able to attract electrons to itself whereas K has a low E.N value. K will give up electrons more readily.

Lookinf at other information in the table, the larger atomic radius and lower ionizaton energy of K are all pointers to how readily it would be able to lose electrons.

We can conclude that K is even a metal.

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

hope this .
