WHat type of elements can a ionic bond be described to
Metals and nonmetals
What is Hydrogen?

What are vertical columns called?
Groups or families (18 in total).
What is the middle of the atom called?
Nucleus
When finding out if a bond is covalent, what do you do first?
Find out if the mixture has two nonmetals. If not, it is ionic
What is the mechanism for an Ionic bond?
Transfering of electrons
What are Noble Gases?
Elements in the far-right column, like Neon and Helium and are extremely unreactive
Why are they called families?
Elements in the same group have similar chemical properties because they have the same number of valence electrons.
What is the model called when we say planetary?
Bohr Model

What is Table Salt ((or Sodium Chloride/NaCl
This common household seasoning is the most famous example of an ionic compound, formed from Sodium and Chlorine.
What are Periods?
The horizontal rows on the periodic table are called this, not to be confused with columns.
Which family is extremely unreactive?
Noble gases (Group 18), due to full valence shells.
Which two subatomic particles are in the middle of the atom?
Protons and Neutrons
What is a covalent bond?
The bonding of a nonmetal and another nonmetal.
What is an Ionic bond?
