In which set of elements would all members be expected to have very similar chemical properties?

• N, O, F

• Na, Mg, K

• Ne, Na, Mg

• S, Se, Si

• O, S, Se

Answer explanation

Elements in the same column will have the same number of valence electrons and similar properties.

Which of the following is NOT a property of metals?

• ductile

• mostly solid at room temperature

• easily broken into pieces

• shiny

• conducts electricity

Answer explanation

Metals are typically shiny, malleable, and ductile, and are excellent conductors of heat and electricity.

Which of the following is a metal?

• sodium (#11)

• neon (#10)

• hydrogen (#1)

• sulfur (#16)

Answer explanation

Metals are located on the left side and in the center of the periodic table, occupying the first two columns and the large central block of transition metals. They are separated from nonmetals by a "stair-step" line between metals and non-metals.

Where would a nonmetal most likely be found on the periodic table?

• a zone in between metals and metalloids

• the top left corner

• the top right corner

• the middle

Answer explanation

Nonmetals are primarily found on the right side of the periodic table, with the exception of hydrogen, which is on the top left. This region includes the upper-right corner, the halogens, and the noble gases.

Which of these describes bromine's location on the periodic table?

• Group 3, Period 7A

• Group 4, Period 7A

• Group 7A, Period 3

• Group 7A, Period 4

Answer explanation

The first (horizontal) row of the periodic table starts with hydrogen and includes helium. The second row starts with lithium, and so on. The group number indicates the (vertical) column where an element can be found.

What is the correct ordering of groups from left to right on the periodic table?

• alkali metals, noble gases, alkaline earth metals, halogens

• alkaline earth metals, alkali metals, halogens, noble gases

• alkali metals, alkaline earth metals, halogens, noble gases

• noble gases, alkali metals, alkaline earth metals, halogens
