The Periodic Table
• Standard 2.1 – Families of Elements
• Standard 2.2 – Electron Configurations
• Standard 2.3 - Ions
Standard 2.1
Understands how elements are arranged in the periodic table, and how this arrangement shows repeating patterns among elements with similar properties (e.g., numbers of protons, neutrons, and electrons; relation between atomic number
and atomic mass)
An atom of magnesium would be the most similar to _______ in terms of its physical and
chemical properties.

1. Oxygen is a gas and dubnium is a solid.
2. Elements with many protons in the nucleus are unstable and require lots of neutrons to reduce the pushing force between protons.
3. Dubnium has many more isotopes than oxygen.

Standard 2.3
Knows that the number of electrons in an atom determines whether the atom is electrically
neutral or an ion (i.e., electrically neutral atoms contain equal numbers of protons and electrons; a
positively charged atom has lost one or more electrons; a negatively charged atom has gained
one or more electrons)
