ron, resulting in higher ionization energies. Q4: Why does electronegativity decrease down a group? A: The addition of electron shells down a group causes valence electrons to be farther from the nucleus, reducing t
ps. Recognize the difference between metals, nonmetals, and metalloids. Predict element properties based on their position. Explore trends such as ionization energy and atomic radius. These goals provide a solid founda
he modern era of superheavy element research. 2. Livermorium (Lv) Naming: After Livermore, California. Context: Honors the Lawrence Livermore National Laboratory where the element was synthesized. 3. Tennessine (Ts) Naming: After Tennessee, home t
re added too, they go into the same shell and do not shield each other effectively. What Causes the Increase in Ionization Energy Across a Period? Ionization energy rises because as atomic radius shrinks, electrons are held more tightly by the nucleus. Removing an electron requires more energy since
resight in leaving gaps for undiscovered elements and predicting their properties marked a turning point. Refinements and Modern Periodic Table Henry Moseley (1913): Established the concept of atomic number, leading to the correction of some inconsistencies in Mendeleev’s tab
