Total questions: 28
Worksheet time: 24mins
what are bonds that have electrostatic forces between oppositely charged ions? (These are often metals with Nonmetals)
covalet bond
metallic bond
Ionic bonds
octet bond
What are some traits of ionic bonding?
They share valence electrons, and they are an exception to the octet rule
Formula starts with a metal, Electrolytes - conduct electricity in water, and soluble in water
Can be solids, liquids, and gases, and they tend to glow in the dark
polar bonds and liquids which means they tend to have a greater radii point
Crystalline solids, strong bonds, and high melting points
What are bonds that share valence electrons (Nonmetals with nonmetals)?
(a)
Draw the following as indicated:
In a number line from 0 to 2, label Nonpolar, polar, and ionic bond using E.N. differences.
True or false: In metallic bonds, valence electrons move from atom to atom.
True
False
Draw partial negative/positive where needed.
use this molecule- B - Cl
An ___ attraction exists between an ION and the partial charge on the end of a polar molecule (aka dipole).
Ion- ion
Ion - Dipole
Dipole-Dipole
None of the above
Ionic bonds have a ___ ___ that have a 3-d, repeated unit cell.
(a)
What rule states that atoms share, lose, or gain valence electrons to obtain eight valence electrons.
Heisenberg Uncertainty Principle
Octet Rule
True or false: triple bonds share 6 e-s, and are the shortest and strongest bond out of the three bonds.
True
False
Which of the following describe metallic bonds?
Metallic bonds are formed when metals' nuclei share delocalized, or 'free' electrons.
Most molecules have _ bonding domains
(a)
From which suborbital should you take a valence electron from first?
F
P
D
S
True or false: Electronegativity differences determine the type of bond (polarity of the BOND).
False
True
Ionic bonds ___ electrons from a ___(low I.E) to a ___ (high I.E).
How do you calculate the number of bonds in a molecule? ( use L and H)
(a)
True or false: The Valence Shell Electron Pair Repulsion Theory is used to determine the shape of a molecule using shared/ unshared valence electrons.
False
True
The H bond in water causes water to have a unusually high ___.
color when dissolved with an acid
texture in gravity
melting point
Low melting point, can be solids, liquids, or gases, solids can be pliable, and have odor. These are traits of which type of bond?
(a)
What are some rules to follow for covalent compounds?
Make molecules symmetrical if possible
Place the single atom in the middle and make triple and double if not enough for 1
They should always be linear if only two atoms are named, regardless of the subscript
H is always on the outside and is stable with 2 electrons
Make octets w/ exceptions, and make pairs
What are the three electrolyte categories?
Proteins, Carbohydrates, Fats
Acids, Bases, Salts (ionic)
The ___ ___ ___ or Van de Waals states that instantaneous attraction occurs when the electrons shift to one side of a molecule. It is short-lived and occurs in all molecules. It is also the weakest of all the bonds.
(a)
What is a type of dipole-dipole attraction between the Hydrogen (H) atom in a polar molecule and a O, F, N, or Cl in another polar molecule
The (a) , or Lewis structures, show valence electrons around the symbol as dots.
Intermolecular forces (IMF's) are ...
Forces from atoms to molecules; they help a covalent bond be held stronger together
attractions between molecules; Weaker than ionic or covalent bonds
Forces between atoms; stronger than regular bonds and carry more charge
The ___ ___ is a region around the central atom in which the electrons are concentrated.
(a)
Name the bonds from strongest to weakest.
