On and below the stairs
Where are the transitional metals
It’s the d block elements (Grp: 3-12)
What is group 1
Alkali metals (expect H)
What is group 2
Alkaline Earth metals
What is group seventeen
Halogens
What is group eighteen
Noble gases
What are the two elements that are liquid at room temp?
Br and Hg
What elements are gases at room temp?
H, group 18, N, O, F, and Cl
What are the characteristics of metals?
They are malleable, are good heat and electric conductors, are shiny LUSTER, can be easily corroded or oxidized, react with H20
Metals are likely to lose what?
Electrons and form cations
what does metallic character mean?
How reactive an element is
How does metallic character increase in metals
What are the characteristics of non-metals?
Brittle, break apart easily, lack of luster (DULL), non-conductor DOES NOT conduct heat or energy
Non-metals tend to gain what?
ELECTRONS, becoming anions (Negatively charged ions)
What are the seven diatomic molecules?
N2, O2, F2, Cl2, Br2, I2, and H2
What are the six metalloids?
B, Si, Ge, As, Sb, Te (Po and At can be considered metalloids but for this test she’s saying we don’t need to know that)
What are the characteristics of metalloids?
It’s a mix between metals and nonmetals, they can gain or lose electrons, they are semi conductors
What do transition metals form and why?
Colored compounds due to the various charges
Mn can have a charge from +2 to +7
What are lanthanides and what atomic numbers are they?
They are “Rare earths” with the atomic numbers 57 to 71
Where are anctinides?
They are atomic numbers 89 to 103 MANY OF THEM ARE REDIOACTIVE
What are the properties of alkali metals?
They are the most reactive, they exist only as compounds in nature, and they only lose one electron
How does reactivity increase? (Alkali metals)
They increase going down the group
