Test Review Periodic Trends, Electrons, and Ionic Bonding

Multiple Choice

Which element has the smaller atomic radius: potassium (K) or bromine (Br)?

• potassium (K)

• bromine (Br)

Multiple Choice

Which Element is a gas at room temperature

• B

• C

• N

Multiple Choice

Which element has the greatest ionization energy: Aluminum (Al)    or    Chlorine (Cl)?

• Aluminum (Al)

• Chlorine (Cl)

Multiple Choice

Which element has the greatest electronegativity: Nitrogen (N) or Arsenic (As)?

• Nitrogen (N)

• Arsenic (As)

Multiple Choice

Which group of the periodic table is composed of inert (not reactive)  gases?

• alkali metals

• alkaline earth metals

• halogens

• noble gases

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

The atom with the largest atomic radius in Group 18 is - 

• Ar

• He

• Kr

• Rn

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

Francium (Fr) has the lowest ionization energy in Group 1 because - 

• it has the smallest number of valence electrons

• it has the greatest atomic mass

• it has the greatest number of protons, so it attracts its electrons the strongest

• its 1 valence electron is very far from the nucleus, so little energy is needed to remove it

Multiple Choice

Families all have similar 

• Names

• atomic numbers

• atomic masses

• properties

Multiple Choice

Which has the greater Electronegativity:  H or F?

• H

• F

Multiple Choice

This is a correct dot diagram for neon (Ne)

• True

• False

Multiple Choice

By replacing the element symbol, this could be the dot diagram of

• Mg

• Cl

• C

• O

Multiple Choice

What does an atom's group number help us determine?

• Number of protons
• Number of electrons
• Number of valence electrons
• Number of shells

Fill in the Blank

Multiple Choice

The chemical bond that forms when electrons are transferred is called:

• Ionic

• hydrogen

• covalent

Multiple Choice

The chemical bond that forms when electrons are shared is called:
