Trends of the Periodic Table

Vertical columns of elements (families) on the periodic table with similar  properties

• groups

• periods

• quadrants

• rows

Vertical columns of elements (these are also known as a "family") - they also have the same number of valence electrons and are known as ________________.

• groups

• periods

• quadrants

• rows

The horizontal rows on the periodic table, which indicate the number of energy levels/orbitals that an atom has, are called ___________.

• Periods

• Element

• Atomic Number

• Group

How is the Periodic Table arranged?

• Increasing atomic mass

• Increasing atomic number

• Decreasing atomic mass

• Decreasing atomic number

Which of the following is true of atomic radius?

• The radius is mainly due to how large an atom's nucleus is.

• The radius is mainly due to the size of the electron cloud.

• The atomic radius is a way we measure the mass of an atom.

• Neutrons account for the majority of an atom's radius.

What is the name of Groups 17?

• Alkali Metals

• Alkali Earth Metals

• Transition Metals

• Halogens

What type of elements touch the zigzag line?

• Metals

• Nonmetals

• Metalloids

• Solids

Where are the nonmetals on the Periodic Table?

• To the left

• In the upper right hand corner

• On the zigzag line

• At the bottom

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

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.
