What is the overall direction for Atomic Radius?
Towards Francium, decreasing from left to right and decreasing up to down
100
What are the dots called around an element symbol?
valence electrons
100
Is H2O polar or nonpolar? Explain
Water is polar because its bent shape and unequal sharing of electrons between oxygen and hydrogen create a positive and negative end
100
How many bonds does oxygen want?
2 bonds
100
What is the formula for dihydrogen monoxide
H2O
200
What is higher in the Ionization energy: Silicon or Phosphorus?
Phosphorus
200
How many valence electrons does Strontium have?
2
200
What are the forces found on HF?
Hydrogen bonding
200
What is the difference between covalent and ionic bonding?
covalent bonds: nonmetal and nonmetal and sharing electrons
ionic bonds: metal and nonmetal and transferring electrons
200
What is the name for P5S4
pentaphosphorus tetrasilicide
300
What element has the highest electronegativity?
Fluorine
300
Draw the Lewis structure for Selenium
300
Can you explain why larger molecules with similar numbers of electrons can have different boiling points, and how London dispersion forces relate to this?
because they have more electrons that are farther from the nucleus, making their electron clouds more polarizable

400
Why does the boiling point of halogens (F₂, Cl₂, Br₂, I₂) increase with molecular weight, and what intermolecular forces are responsible?
larger, heavier molecules have more electrons and a larger surface area, leading to stronger London dispersion forces
