Classification of the Elements

The atoms along the staircase are called 

• metals

• nonmetals

• metalloids

• noble gases

The vertical (up and down) columns in the Periodic Table are called

• groups

• towers

• periods

• atomic numbers

Sodium (Na) is found in group 

• 1

• 2

• 3

• 4

what group of element does the s-block contain?

• group 1-2-3

• group 1-2

• group 3-12

• group 13-18

Select the element that is a nonmetal

The elements touching the staircase [which is shown in red here] are called

• metals

• nonmetals

• semimetals

• noble gases

Match the element to the correct descriptive term.Match the following

• Metalloid

• Nickel

• Noble gas

• Neon

• Transition metal

• Beryllium

• Alkaline earth metal

• Thorium

• Inner transition metal

• Silicon

Why are both hydrogen and cesium s-block elements, when hydrogen has one electron and cesium has 55?

• All blocks contain at least one element from each period.

• Blocks of elements on the periodic table are based only on an element's valence electrons.

• The s-block includes only the most reactive elements.

• They have identical electron configurations.
