How is the periodic table arranged?
Into four blocks associated with the four sublevels; s, p, d, and f
What are groups and periods?
Vertical columns and horizontal rows respectively
What is the period number?
The outer energy level occupied by electrons
What two things can be deduced based on an elements position on the periodic table?
The principal energy level and the number of valence electrons
What three positions are shown on the periodic table?
Metals, non-metals, and metalloids
What is the periodic table exemplary of?
This is an example of obtaining evidence for scientific theories by making and testing predictions based on them, as shown by testing of various scientists to establish different elements and their properties, searches that continue to this day
What five trends exist on the periodic table?
Atomic radius
Ionic radius
Ionization energy
Electron affinity
Electronegativity
Why are trends in metallic and non-metallic behaviour observed?
Because of the five periodicity trends
What is the trend of oxides across a period?
They move from basic to amphoteric to acidic
Why are patterns important in science?
They allow scientists to easily utilize different things, such as patterns on the periodic table allowing for easy identification of traits leading to synthesizing of new substances
