Question

trends on the periodic table worksheet
name

1. how is a group different then a period on the periodic table?
2. what does magnesium, iron, potassium, and copper have in common? (use the color - coded periodic table)

Explanation:

1. Groups in the periodic table are vertical columns. Elements in the same group have the same number of valence electrons and similar chemical properties. Periods are horizontal rows. As you move across a period, the number of protons, electrons, and atomic number increase.
2. Magnesium (Mg), Iron (Fe), Potassium (K), and Copper (Cu) are all metals. Metals are typically good conductors of heat and electricity, malleable, and ductile. They are usually found on the left - hand side and in the middle of the periodic table.

Answer:

1. Groups are vertical columns with elements having similar chemical properties due to the same number of valence electrons. Periods are horizontal rows where properties change gradually as the atomic number increases.
2. They are all metals, which are generally good conductors of heat and electricity, malleable, and ductile.
