The energy required to remove an electron from an atom
A full octet makes the noble gases nonreactive.
one should look for predictable changes and patterns
The correct answer is: Atoms are often more stable when bonded to other atoms
Helium has the highest first ionization energy and francium has the lowest first ionization energy.
Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.
question: which of the following elements is the smallest?
answer: chlorine (CI)
For example this is a salt.
The answer is [Kr]5s^2
