• in the same group.
• in different periods.
• to the right and left of each other.

In the modern periodic table, elements are arranged by:

• atomic mass

• atomic number

• valence electrons

• protons, neutrons, and isotopes
• neutrons, isotopes, and electrons
• positives, negatives, and electrons
• protons, neutrons, and electrons
