Atomic Radius
Ionization Energy
Electronegativity
Final Jeopardy
100
Why do radii DECREASE across a period?
There is an increase in positive charge in the nucleus (more protons) pulling on the electrons (opposites attract)
100
What Is Ionization Energy?
The ability to lose electrons
Done using isolated atoms in the gas phase
100
Which Periodic Table family has a low electronegativity?
Alkali Metals
200
Which element has a smaller radius, Sodium or Sulfur?
Sulfur
200
Why does Ionization Energy INCREASE across a period?
Atoms don't want to give up their electrons (octet rule)
200
Which Periodic Table family has a HIGH electronegativity?
Halogens
300
Why do radii increase as you travel down a family?
There is an increase in orbitals
300
Why does Ionization Energy DECREASE down a family?
Electrons are further away from the protons in the nucleus
300
Why does electronegativity DECREASE by group?
There is a weaker attraction between nucleus and valence electrons because the atomic radius increases
400
Which element has a bigger radius, Gallium or Aluminum?
Aluminum
400
Which Periodic Table Family has the LOWEST Ionization Energy?
Alkali Metals (tend to lose electrons easily)
400
Why does electronegativity INCREASE by period?
As you go by each period the number of charges on the nucleus increases because the number of protons increases
500
Which element has a bigger radius, Potassium or Krypton?
Potassium
500
Which Periodic Table family has the HIGHEST Ionization Energy?
Noble Gases (they hold on to the electrons they have)
500
Who came up with an electronegativity scale?
Linus Pauling
500
Was this a good Jeopardy?
Of course
