Flashcards

What is a period in the periodic table?

The periodic table is arranged in rows called periods. Periods go from left to right and represent energy levels in an atom.

What is the basis of organization in the periodic table?

Elements in the periodic table are arranged by increasing atomic number. This means the order is based on the number of protons in the atom.

What are the main properties of metals?

Metals are generally shiny, can be pounded into shapes (malleable), can be drawn into wires (ductile), and conduct heat and electricity well.

Where are metals found on the periodic table?

Metals are located on the left side of the periodic table, while nonmetals are on the right.
