#1
Which of the following elements has the highest electronegativity?
Chlorine
ExplanationElectronegativity increases towards fluorine in the periodic table.
#2
What is the trend in atomic radius as you move from left to right across a period in the periodic table?
Decreases
ExplanationAtomic radius decreases due to increased effective nuclear charge.
#3
Which of the following elements has the highest ionization energy?
Aluminum
ExplanationAluminum has high ionization energy due to its relatively small atomic size.
#4
What is the general trend of electronegativity as you move down a group in the periodic table?
Decreases
ExplanationElectronegativity decreases down a group due to increasing atomic size.
#5
What is the trend in electron affinity as you move from left to right across a period in the periodic table?
Increases
ExplanationElectron affinity increases due to stronger attraction for added electrons.
#6
Which of the following elements has the smallest atomic radius?
Rubidium
ExplanationRubidium has a larger atomic radius due to its lower effective nuclear charge.
#7
Which of the following elements has the highest melting point?
Tungsten
ExplanationTungsten has a high melting point due to its strong metallic bonds.
#8
Which of the following elements has the lowest electronegativity?
Hydrogen
ExplanationHydrogen has the lowest electronegativity among the elements.
