e. when providing formulas for molecular compounds, you should always simplify the ratios of the atoms of each type. t/f
f. to complete the outermost shell, some atoms share their electrons with other atoms to achieve a stable octet. t/f

Explanation:

Step1: Analyze molecular - compound formation

Molecular compounds are formed between non - metals, not two metals. So the statement "Molecular compounds are formed between two metals" is False (F).

Step2: Analyze bonding in molecular compounds

Molecular compounds are a result of sharing of electrons (covalent bonding), not transfer of electrons. So the statement "Molecular compounds are a result of transfer of electrons" is False (F).

Step3: Analyze binary - compound prefixes

Binary compounds do not always have a prefix that ends in - ide. The naming of binary compounds depends on whether they are ionic or molecular. So the statement "Binary compounds have a prefix that ends in - ide" is False (F).

Step4: Analyze prefix use in binary - compound naming

Prefixes are used in naming binary molecular compounds to indicate the number of each type of atom. But not all binary compounds are molecular. So the statement "Prefixes are used in naming binary compounds to indicate the total number of atoms in the compound" is False (F).

Step5: Analyze formula - writing for molecular compounds

When providing formulas for molecular compounds, you do not always simplify the ratios of the atoms of each type. For example, in empirical and molecular formulas, the molecular formula may not be the simplified form. So the statement "When providing formulas for molecular compounds, you should always simplify the ratios of the atoms of each type" is False (F).

Step6: Analyze electron - sharing for octet stability

To complete the outermost shell, some atoms share their electrons with other atoms to achieve a stable octet. This is the basis of covalent bonding in molecular compounds. So the statement "To complete the outermost shell, some atoms share their electrons with other atoms to achieve a stable octet" is True (T).

Answer:

a. F
b. F
c. F
d. F
e. F
f. T
