Molecular Compounds Flashcards
Molecular Compound Definition (A compound formed when)
A compound formed when atoms of two or more different elements share electrons.
What are Molecular Compounds also known as?
Covalent Compounds
What are Molecular Compounds usually composed of? (in terms of types of elements)
Two or more different nonmetals.
How does a molecular compound form? (What do they share a pair of to form a one of what?)
When atoms share a pair of electrons to form a covalent bond?
What happens during a covalent bond?
The shared electrons are attracted to the nuclei of both atoms; ultimately, this attraction holds the atoms together.
True or False: Unlike electrons in an ionic compound, electrons in a molecular compound are not transferred between atoms, so the atoms remain uncharged.
True
The formation of a molecular compound is based on the same principle as the formation of an ionic compounds, which is the following:
The stability that is associated with a full outer energy level of electrons.
What are molecular compounds composed of? (Individual what?)
Individual Molecules
Molecule Definition (more than one covalent bond)
A neutral particle composed of two or more atoms joined together by covalent bonds.
True or False: Each molecule is composed of a set number of atoms of each element.
True
What is the term molecule also used to describe?
Two or more atoms of the same element that are joined by a covalent bond.
What are the elements that exist in this form (the diatomic molecules-7 of them)?
Hydrogen, Nitrogen, Oxygen, Chlorine, Bromine, Iodine and Fluorine.
True or False: Diatomic molecules are not compounds because they contain only one kind of atom.
True
Binary Molecular Compound Definition (also, what are they joined by?)
A compound that is composed of two non-metals joined by one or more covalent bonds.
Use the worksheets under “Chemistry Unit Test Review” to practice naming molecular compounds using the prefixes when given chemical formulas, to write the chemical formula using the names, and to draw Bohr-Rutherford and Lewis Dot diagrams.
Depending on comfort level.
