Predicting Relative Sizes of Atomic Radii
Referring to the periodic table, arrange (as much as possible) the atoms B, C, Al, and Si in order of increasing size.
By referring to the periodic table, but not to Figure place the following atoms in order of increasing bonding atomic radius: N, O, P, Ge.
Which part of the periodic table (top/bottom, left/right) has the elements with the largest atoms?
▲ Figure Trends in bonding atomic radii for periods 1 through 5.
Lecture – January 11 Chapter 1 Atomic Structure Nucleus – consists of protons (+ charge) and neutrons (neutral) Essentially all of the atom’s mass is located in the nucleus Mass Number – the number of protons plus the number of neutrons Atomic Number – the number of protons Atoms with the same atomic number...
