Electronegativity and Metals

Multiple Choice

Which of the following will have a larger radius than Zinc?

• Gallium
• Aluminum
• Magnesium
• Strontium

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

As you move down the periodic table atoms get bigger.  This is because ____________.

• The atoms have more mass.
• The atoms have more protons.
• The atoms have more energy levels
• The atoms have more nuetrons

Multiple Choice

Which element has the greater ionization energy?

• Lead
• Silicon

Multiple Choice

What is ionization energy?

• Energy needed to destroy an atom
• Energy required to remove an electron
• Energy needed to split an electron
• Energy required to add an electron

Multiple Choice

As you look down a group, ionization energy and electronegativity

• increases

• decreases

Multiple Choice

Which of the following is NOT typically considered a periodic trend discussed in chemistry?

• Atomic radius

• Ionization energy

• Electronegativity

• Molecular polarity

Open Ended

Why do you think understanding periodic trends such as atomic radius, ionization energy, and electron affinity is important in chemistry?

Multiple Choice

Which of the following best describes electronegativity?

• An atom's attraction to an electron

• The number of protons in an atom

• The ability of an atom to lose electrons

• The mass of an atom
