Periodic Trends CFU

The symbols W, X, Y, and Z represent four elements shown on the outline of a periodic table.
Which element has the LARGEST ATOMIC RADIUS?

• W
• X
• Y
• Z

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

As you move across the periodic table atoms tend to get smaller because, ______________.

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

Which atom has the largest atomic radius?

• potassium
• rubidium 
• francium
• cesium

Which periodic group has the smallest atomic radius?

• Alkali metals
• Halogens
• Noble Gases
• Transition metals

The symbols W, X, Y, and Z represent four elements shown on the outline of a periodic table.
Which element has the HIGHEST Ionization Energy?

• W
• X
• Y
• Z

Ionization energy is...

• 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

Select ALL that explain the ionization energy trend within periods going left to right

• electrons are closer to the nucleus

• their is a weak pull between electrons from the nucleus, making them easily moveable

• feel more of a pull from nucleus, making them harder to move

• electrons are further from the nucleus

Which element has the lowest ionization energy?

• Mg

• Sr

• Ba

• Ca

Which group of elements on the periodic table will have the LARGEST ionization energy?

• Alkali Metals

• Alkaline Earth Metals

• Halogens

• Noble Gases
