Chemical Bonds
These types of elements bond together to form ionic bonds,
metals & nonmetals
The period specifies how many shells an atom has, what does the group specify
amount of valence electrons
This is the number of periodic trends we learned about.
4
It is the name for the middle section of the periodic table?
transition metals
It is what makes metallic bonds hold together.
sea of electrons
These types of elements bond together in covalent bonds.
nonmetals & nonmetals
It is the other thing, besides an address in the periodic table, that the atomic number tells us.
number of protons that an element must have
They are two of the three periodic quantities that increase as we move toward the top and right of the periodic table.
electronegativity, ionization energy,
metal, nonmetal, or metalloid, what is sulfur?
nonmetal
It is the number of single covalent bonds found in methane, CH4.
4
It is what iron does to form the cation Fe+3.
lose three electrons
It is the general guideline that an element tries to obtain 8 electrons in its valence shell in order to obtain a noble gas configuration.
octet rule
Of Sodium, Magnesium, Potassium or Calcium, it is the one with the largest atomic radius.
potassium
It is the name for any element in group 18.
Noble gas
what is the chart that shows proton numbers, trends, families, and all known elements.
Periodic table
It is another name for covalent bonds.
molecular bonds
It is the group that tends to form anions with a charge of (-2).
Group 16
It is the proper order of increasing electronegativity for K, O, Si, and S
K, Si, S, O
It is the name for the family of elements in Group 17.
halogens
what is 6 + 7
13
It is the difference between polar covalent bonds and nonpolar covalent bonds.
nonpolar bonds share electrons equally (0-0.4) while polar bonds share electrons unequally (0.4-1.7)
Draw the electron configuration of Magnesium
2,8,2
They are the places in the periodic table where the periodic trends of electronegativity, electron affinity, and atomic radius have the largest magnitudes.
Electronegativity - up and to the right
Electron affinity - up and to the right
Atomic Radius - down and to the left
It is the name of a bond that has an electronegativity difference of 1.3
Polar Covalent Bond
It is the type of bond that results when two atoms with an electronegativity difference of about (1.7 and above) come together .
Ionic bond
