Radius
What happens to atomic radius as you go down a group. Why?
gets bigger, more energy levels
What is electronegativity?
Realive attraction of e-
Where are the most reactive metals?
Group 1
Non metals want to do what with e-. What ions do they form.
Gain e-, Negative ions
Every element is trying to be like what group and why?
Noble Gases; full octet/ valence shell, stable "happy"
What happens to atomic radius as you go across a period increasing atomic number? WHY?
Decreases b/c same energy levels but higher nuclear charge so more attraction
what is ionization energy?
How much energy it takes to remove outer most e-.
What are the characteristics of metals?
Malleable, good conductors, ductile, luster,
What do metals like to do with their electrons. What ions do they form.
lose e-, Positive ions
What are the 2 liquids on the periodic table and are they nonmetals, metals or metalloids?
Bromine- NM and mercury-M
What happens to the ionic radius of a metal compared to its atomic radius.
Loss of e-, smaller ionic radius than atomic
What happens to ionization energy as you go across a period with increasing atomic number. WHY
Increases bc higher nuclear charge but same energy levels so more attraction of e- to p+ therefore harder to pull e- away
Where are metals located and which metal has the most metallic characteristics.
left of periodic table/ most metallic is Fr
Where can you find oxidation states in your reference tables, what doe oxidation states tell us?
Periodic tables, whether elements gain or lose e-
What are the characteristics of transition metals.
Colored solutions, multiple oxidation states
What happens to the ionic radius of nonmetals compared to its atomic radius?
gain of e-, so bigger ionic radius than atomic
What happens to ionization energy as you go down the group. WHY
decreases b/c more energy shells so less attraction of e- to p+
Where are nonmetals located and what element has the most nonmetallic characteristics?
Right and Fluorine
What group forms a compound of X2O?
Group 1
What is an allotrope? List the allotropes of carbon?
Same element, different structure, different characteristics
Diamond, graphite, charcoal
Where can you find atomic radius, electronegativity, and ionization energy in your reference tables.
Table S
What is the most electronegative element and WHY?
F b/c smallest atom, not many energy levels and high nuclear charge so strong attraction
What are the metalloids?
Along staircase, B, Si, Ge, As, Sb, Te, At
What are the oxidation states of Cl and Mg? How many Cl & Mg atoms do you need if they form a compound.
Mg2+ Cl1-
MgCl2
What are the 7 diatomics?
BrINClHOF
Bromine, Iodine, Nitrogen, Chlorine, Hydrogen, Oxygen, Fluorine
