100
Does K or K2- have a larger radius?
K
100
The energy required to take away electrons.
What is ionization energy?
100
This group is not at all likely to react with any elements, because they already have a full shell of electrons.
What is group 8
100
What family's characteristics are generally non-reactive, with low melting & boiling points?
Noble gases.
100
What is the least reactive group?
Group 8 - noble gases
200
Does Li or Be have a larger ionization energy?
Be
200
The energy released when adding an electron to an atom
What is electron affinity?
200
How likely is Na (element 11) to react with another element?
Very likely, because it's a group 1 element, with only 1 valence electron to get rid of.
200
What family of elements are soft metals, with a charge of +1, and highly reactive?
Alkali Metals
200
Is group 1 more likely to lose or gain electrons?
Lose , because they only need to lose 1 electron to have a full shell.
300
Does He or Fr have a larger electronegativity?
He
300
The ability of atoms in a molecule to attract electrons to themselves
What is electronegativity?
300
Is element 16 or 13 more likely to conduct heat?
Element 16 (aluminum)
300
What group contains the only 3 magnetic elements?
Transition metals
300
How likely are noble gases to gain or lose electrons?
Not likely at all, because they already have a full shell.
400
Does Be or B have a larger electron affinity?
B
400
An atom with a negative charge.
What is an anion?
400
What is the charge of ions formed by alkali earth metals?
+2
400
Describe characteristics of the carbon family.
Somewhat unreactive, have 4 valence electrons, contains 1 nonmetal, 2 metalloids, and 2 metals.
400
List the elements in order of decreasing atomic radius; Na Li, He, Rn.
Na, Li, Rn, He
500
Does Hg or Hg3+ have a larger radius?
Hg
500
The radius of an ion
What is the ionic radius?
500
What group forms a +1 charge of the ions?
What are Alkali Earth Metals?
500
Which group includes the elements flourine, chlorine, bromine, iodine, and astatine?
Halogens
500
What family tends to form ions with a charge of -2 , with 1 gas and the rest solid at room temperature?
Chalcogons
