Multiple Choice

Ionization energy is...

• the energy required to add an electron to a specific atom
• how much energy it takes to remove/knock off 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

Multiple Choice

• the atoms have more mass.
• the atoms have less mass
• the atoms have more protons.
• the atoms have less electrons.

Multiple Choice

• it decreases

• it increases

• it stays the same

Multiple Choice

Multiple Choice

The atoms along the staircase are called 

• metals
• nonmetals
• metalloids
• noble gases

Multiple Choice

What elements are found in the shaded region?

• Metals
• Nonmetals
• Metalloids

Multiple Choice

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

Multiple Choice

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

Multiple Choice

The energy required to remove electrons is the definition of: 

• Electronegativity
• Atomic Number
• Atomic Radius
• Ionization

Multiple Choice

Electronegativity is...

• the ability of an atom to attract 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.
