the properties of two elements are listed below.\nwhich prediction is supported by the information in the table?\nk will give up an electron more easily than br.\nboth k and br will have the same pull on electrons.\nk will have a smaller size in comparison to br.\nboth k and br will produce ions of the same size.
Answer
# Explanation:
## Step1: Analyze ionization energy
Ionization energy is the energy required to remove an electron from an atom. A lower first - ionization energy means it is easier for an atom to give up an electron. For \(K\), the first ionization energy is \(418.8\ kJ/mol\), and for \(Br\) it is \(1140\ kJ/mol\). Since \(418.8<1140\), \(K\) has a lower first ionization energy.
## Step2: Analyze electronegativity
Electronegativity measures the pull of an atom on electrons in a chemical bond. \(Br\) has an electronegativity of \(3.0\) and \(K\) has an electronegativity of \(0.82\). So they do not have the same pull on electrons.
## Step3: Analyze atomic radius
The atomic radius of \(K\) is \(243\ pm\) and that of \(Br\) is \(114\ pm\). So \(K\) has a larger atomic radius than \(Br\).
## Step4: Analyze ionic radius
The ionic radius of \(K\) is \(152.2\ pm\) and that of \(Br\) is \(195\ pm\). So their ions are not of the same size.
# Answer:
\(K\) will give up an electron more easily than \(Br\).
