Atomic Radius
What is Atomic Radius?
What is the size of an atom (from its nucleus to its outermost electrons)
This increases as you down a group?
What Electron Rings
Elements in this category will form cations.
What is metals.
What is outermost.
As you go across a periodic table, the atomic radius of the elements will ______?
What is decreases
Each element in the same ______ has the same number of Valence Electrons.
Elements in this category will form anions.
What is non-metal.
All atoms want _____ valence electrons to be stable.
What is 8.
As you go down a periodic table, the atomic radius of the elements will _____?
What is increases
Oxygen, Carbon, and Helium all belong to this category of elements.
What is non-metal
The radius of an atom will decrease across the periodic table due to the atom having more of these.
What is protons
Elements in this group have one valence electron.
What is group 1.
Rank each element from smallest to largest atomic radius: Magnesium (Mg) Sulfur (S) Chlorine (Cl)
Chlorine Sulfur Magnesium
Sodium, Beryllium and Lithium belong to this category of atoms.
What is metal
Radius of an atom will increase in size as you go down a group on the periodic table due to the atom having more of these.
What is electrons or electron rings
This group of elements have 8 valence electrons and because of this, they are very unreactive.
What are Nobel Gases (Helium, Neon, Argon)
