Don't Overreact!
He was a Danish physicist, and he was the first to apply quantum theory to atomic structure. He developed the "Bohr model" of the atom.
Who was Niels Bohr?

What is the electron configuration of Cl?
The horizontal rows of the Periodic table are called this.
What are Periods?
Ionic bonds form between these two things.
What are metals and non-metals?
He presented a paper showing a periodic table based upon atomic weights.
Who was Dmitri Mendeleev?
3 is the ______ _____ _______ for Cl.
What is the Principle Quantum Number?
The vertical columns of the Periodic Table are called this.
What are Groups?
What is an ion?
This element if Ferromagnetic, meaning it behaves as tiny magnets.
What is Iron?
If Chlorine gained an electron to fulfill the Octet Rule, it would have this charge.
What is a negative charge? (Cl-) (3p6)
Silicon would be most similar to which elements? (will count a few answers)
What is carbon, germanium, tin, lead, flerovium?
An atom that loses electrons becomes this type of ion.
What is a cation?
He is credited with the Wave Mechanics Theory. He came up with the probabilities of finding electrons in regions he called orbitals. The shapes of the balloons you used in a recent lab exercise demonstrate the orbitals where you are most likely to find the electrons. These replaced Niels Bohr's orbits.

The elements in this group lose 2 electrons.
What is Group 2?
An atom that gains electrons becomes this type of ion.
What is an anion?
Fluorine, Chlorine, Bromine, Iodine, and Astatine are also known as by this name.
What are Halogens?
To satisfy the Octet Rule, Ca becomes this.
What is Ca++
The elements in this group gain 3 electrons.
What is Group 15?
The chemical formula for magnesium chloride.
What is MgCl2?
