Periodic Table Families Groups Periods Spdf Block

The family of elements that have one valence electron is the:

• noble gas family
• halogen family
• alkaline earth metal family
• alkali metal family

Which family of elements have 7 valence electrons?

• the alkali metal family
• the boron group
• the nitrogen group
• the halogen family

Which statement is true about the alkaline earth metal family?

• They have 2 valence electrons.
• They are found on the right side of the periodic table.
• They form -2 charges.
• They tend to gain valence electrons.

An atom that has 1, 2, 3, or 4 valence electrons is likely to be:

• a non-metal atom
• a metalloid atom
• a metal atom
• a noble gas

An atom that has 5, 6, 7, or 8 valence electrons is likely to be:

• an alkali metal atom
• an alkaline earth metal atom
• a non-metal atom
• a transition metal atom

Dmitri Mendeleev (the first man to get credit for trying to create a periodic table) organized his elements by increasing:

• atomic number

• atomic mass

• charge

• density

The Lanthanide elements are known as the:

• Common earth metals
• Alkaline earth metals
• Rare earth metals
• Heavy earth metals

Which family of elements is least likely to gain or lose valence electrons because they do not chemically react?

• the noble gas family
• the halogen family
• the transition metals
• the carbon family

Which statement is true about the carbon family?

• They are all non-metals.
• They all have four valence electrons.
• They are all metals.
• They do not react with other elements.

Most of the elements to the LEFT of the zig-zag line are:

• metals
• metalloids
• non-metals
• noble gases
