What trend is observed in the reactivity of alkali metals (Group 1) as you move down the group?
Reactivity decreases
Reactivity increases
Reactivity stays the same
They become nonmetals
What do elements in the same group (vertical column) of the Periodic Table have in common?
Same number of protons
Same number of neutrons
Similar chemical properties
Same atomic mass
Which statement best explains why halogens (Group 17) are highly reactive?
They have a full outer shell of electrons
They need to gain one electron to achieve a stable configuration
They are metals
They have low atomic numbers
How does the reactivity of nonmetals generally change as you move up Group 17 (the halogens)?
Reactivity increases
Reactivity decreases
Reactivity stays the same
They become metals
A student claims that elements in the same period have similar properties. Use your knowledge of the Periodic Table to evaluate this claim.
The claim is correct; periods have similar properties.
The claim is incorrect; groups, not periods, have similar properties.
The claim is correct; periods have the same number of valence electrons.
The claim is incorrect; periods are not related to properties.
Given the following elements: sodium (Na), magnesium (Mg), and aluminum (Al), predict which will be the most reactive and explain why.
Sodium, because it has the most valence electrons
Magnesium, because it is in the middle of the period
Sodium, because it has only one valence electron and loses it easily
Aluminum, because it is a metalloid
Match the following type of elements with their properties
Shiny, mostly solids, good conductors.
Many gases brittle solids, low conductor
Characteristics of both, semiconductors
What are the most likely positions of element A and element B on the periodic table?
Both elements A and B are on the left of the periodic table.
Both elements A and B are on the right of the periodic table.
The element A is on the left of the periodic table, and element B is on the right of the periodic table.
The element A is on the right of the periodic table, and element B is on the left of the periodic table.
The model of the periodic table below shows the locations of four elements.
