Covalent Bonds
How many covalent bonds can nitrogen have?
3
What type of covalent bond diagram only shows the outer shell of electrons?
Dot-and-cross diagrams
A nonpolar bond is formed when two atoms share electrons unequally.
F
An ionic compound is a compound that consists of molecules made of atoms that are covalently bonded.
F
Because the electrons in a molecule of hydrogen fluoride (HF) are more strongly pulled toward the fluorine atom, the molecule is nonpolar.
F
When electrons are transferred between two atoms, a covalent bond is formed.
F
Low melting points and lack of electrical conductivity are properties of molecular compounds.
T
Molecular compounds that dissolve in water do not conduct electricity because no charged ions are present.
T
A chemical bond formed when atoms share three pairs of electrons is __________.
a triple bond
Molecular compounds do not conduct electricity because they
do not break up into ions.
Which is a property shared by most molecular compounds?
low melting point
A covalent bond in which electrons are shared unequally is
polar.
What is a double bond?
two pairs of electrons shared between two atoms
