Ionization energy is defined as ____.

• the energy required to add an electron to a specific atom

• how much energy it takes to remove an electron from an atom

• the energy required to shield the outer electrons from the nucleus

• a measure of the ability of an atom to attract electrons

Electronegativity is...

• the ability of an atom to attract/ accept electrons
• the ability of an atom to lose electrons
• the energy required to remove an electron from a specific atom
• how easy it is to make friends.

NGSS.HS-PS1-2

As you move down a group, atomic radius increases because ____.

• you add more and more neutrons

• you add more and more protons

• you add more and more shells (energy levels)

• you add more atomic mass

NGSS.HS-PS1-1

As you move across the periodic table from left to right, the atomic radius decreases.  This is because - 

• the number of protons increases, so attraction to electrons increases
• the number of energy levels increases
• the number of electrons increases
• the atomic mass increases

NGSS.HS-PS1-2

Which of the atoms pictured would have the lower ionization energy and why?

• Atom A because it it bigger

• Atom A because the outer electrons are not "held" as tightly as those in atom B

• Atom B because it is smaller

• Atom B because the outer electrons have a greater attraction for the nucleus.
