B
Cular compounds
2) Molecule
A
chemical compound whose simplest units are molecules
B
neutral group of atoms held together by covalent bonds
3) Molecular compound
A
neutral group of atoms held together by covalent bonds
B
chemical compound whose simplest units are molecules
4) Molecular Compounds usually form SPONCH which is?
A
Small,pie,ox,night,card,higher
B
Sulfur,Phosphorus,Oxygen,Nitrogen,Carbon,and Hydrogen
5) Covalent Bonds are much:
A
stronger than ionic bonds
B
weaker than ionic bonds
6) Chemical formula:
A
gives numbers of atoms of each kind in a chemical compound–uses symbols and subscripts.(H2O C6 H12O6)
B
chemical compound
7) The average distance between two bonded atoms at their lowest potential energy is called:
A
bond length
B
bond width
C
bond height
8) In forming a covalent bond, the hydrogen atoms:
A
sfggwggregre
B
release energy(The same amount of energy must be added to separate the bonded atoms)
9) Bond energy is:
A
ssssssssssssfvwfvffvs
B
the energy required to break a chemical bond and form neutral isolated atoms
10) The stronger the bond, the shorter the:
A
bond length (distance) and the higher the bond energy value
B
All Correct
C
An inverse proportion exist between bond energy and length.
11) A bond forms when:
A
atoms are a certain distance from each other(low energy state)
B
cdffew
12) If closer together or farther apart atoms:
A
srwrgr
B
will be in a unstable situation
13) The octet rule is a chemical rule of thumb that reflects the theory that: main-group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.
A
false
B
true
14) Ionic Bonds:
A
Chemical Compound
B
composed of positive ions (cations) and negative ions (anions) that combine so tpositive and negative charges are equal
15) The chemical formula of an ionic compound shows:
A
gsfhrea
B
the ratio of the ions present in a sample of any size
16) A formula unit is the:
A
biggest unit of atoms from which an ionic compound’s formula can be established
B
smallest unit of atoms from which an ionic compound’s formula can be established
17) Most ionic compounds exist as:
A
crystalline solids
18) A crystal of any ionic compound is a:
A
three-dimensional network of positive and negative ions mutually attracted to each other
B
four-dimensional network of positive and negative ions mutually attracted to each other
19) Ionic compounds tend to form so that each atom:
A
gains or loses electrons from its highest occupied energy level to form an octet
B
loses electrons from its highest occupied energy level to form an octet
20) The simplest ratio of an Ionic compound’s ions is a
A
Ionic compounds organize in a characteristic crystal lattice of alternating positive negative ions.=True
B
Formula unit....Not molecule
