Question

following question(s).
in class, students investigated patterns of elements in the periodic table of the elements. their teacher pointed out a few properties of some common elements. helium is the lightest inert gas in air. magnesium burns with a bright white flame. gold and silver are dense metals. table salt (sodium chloride) is a combination of two reactive elements. some properties of common elements are shown in the data table below.
properties of some common elements
which statement best explains what happens to the atoms in gold (au) when the temperature of the metal increases?
the atoms move more slowly.
the atoms move more quickly.
the motion of the atoms stays the same.
the motion of the atoms becomes very orderly.

Explanation:

When the temperature of a substance increases, the kinetic energy of its atoms or molecules increases. Kinetic energy is related to the motion of particles. For gold (a solid at room temperature), as the temperature goes up, the atoms gain more kinetic energy. This means they vibrate more vigorously, which is equivalent to moving more quickly.

Answer:

The atoms move more quickly.
