What distance is measured for an atomic radius?
The center of the nucleus to the edge of the electron cloud
Rule that states that atoms lose, gain, or share electrons in order to acquire the stable electron configuration of a noble gas.
Octet Rule
In the modern periodic table, elements are arranged by increasing number of protons
True

What is electronegativity?
The ability of an atom to gain electrons
A measure of an atom's ability to attract shared electrons to itself
