    What is periodicity in the periodic table?

    It reflects the repeating pattern of properties based on atomic number.

    Why are there patterns in the periodic table?

    Similar valence electron counts lead to similar chemical properties.

    How are the characteristics of atoms connected?

    They determine an atom's chemical behavior and properties.

    Why do elements in the same group share similar properties?

    They possess the same number of valence electrons.

    What are groups and periods in the periodic table?

    Groups are vertical columns; periods are horizontal rows.

    Why was Dmitri Mendeleev important to the periodic table?

    He predicted undiscovered elements by leaving gaps in his table.

    What is a Bohr model of an atom?

    It illustrates electrons in energy levels around a nucleus.

    How are isotopes different from each other?

    They have the same protons but different neutrons.

    How do you calculate protons, neutrons, and valence electrons?

    Protons equal atomic number; neutrons equal mass number minus atomic number.

    What is the difference between atomic number and mass number?

    Atomic number counts protons; mass number counts protons and neutrons.

    What is an electron dot structure (Lewis dot structure)?

    It shows valence electrons as dots around the element symbol.

    What are compounds?

    They are formed when elements chemically bond together.

    What types of chemical bonds exist?

    Ionic bonds involve electron transfer; covalent bonds involve electron sharing.

    What are intermolecular forces?

    They are weak attractions between molecules.

    What is the octet rule?

    Atoms aim for eight electrons in their outer shell.

    How can ionic properties help identify unknown solids?

    Ionic compounds have high melting points and conduct electricity in water.
