Noble with big d-orbitals
Transition metals have their outermost electrons in which orbital.
The d-orbital
The elemental formulas for the halogens are the following
F, Cl, Br, I
True or False
False
They are diatomic
The interaction between which two things play a large role in the size of the atom?
Nucleus and Electrons or
Protons and Electrons
What is the name for the group 1 elements?
Alkali metals
TiCl3 is purple. What transition metal property is this a color of.
The ability to form colored complexes.
What is the most reactive Halogen?
Fluorine
True or false
Atomic radius increases as we move to the right of the periodic table.
False
Name one characteristic of the group 1 Metals
Reactive,Lustrous,Soft
How many valence electrons do the noble gasses have?
8
What is the common ionic charge of halogens in compounds?
-1
Why does the atomic radius increase down the group of the periodic tale?
Addition of an energy level or
Electrons added on next energy level
What kind of ion do the group one metals tend to form?
+1 Ions
Why are the noble gasses said to be inert?
They have a full outer energy level (sub shell). No need to accept or give electrons.
What is the trend in density as we go down group 7
Density of halogens increases
What is meant by the term ionization energy?
Energy required to remove one mol of electrons from one mol of gas atoms.
Energy to remove one of the outermost electrons
Would you expect the ionization energy of group 1 metals to be greater or less than that of group 2
Less than. Group 2 will have an additional proton.
True or false? transition metals can have varying ionic charges or oxidation states.
True
What is the product, if any of the following reaction?
NaF + Br2->
No reaction
Why does Oxygen have a higher first ionization energy than Polonium
Oxygen has a smaller radius
Polonium has more electron that increase shielding
Why would reactivity increase going down the group 1 metals?
Atomic radius increases allowing for outer electrons to be exchanged easily.
Outer electrons are easier to remove.
