2. The questions below mirror the questions in the tutorial. Answer the questions in the formative as you work through the tutorial.
How does the movement of electrons change when two atoms are close together?
What happens if you try to move the atoms very close together?
Draw that happens when two atoms are close enough to form a covalent bond. Be sure to use arrows to indicate the attraction between the nuclei and the electrons.
Which group of elements form covalent bonds and why
When the potential energy is lowest, the attraction between the two atoms is strongest.
Potential energy increases when atoms get too close because
A bond length is
The lower the potential energy, the more stable the system.
What does a solid single line represent when we draw a covalently bonded molecule?
How many electrons are shared in a single bond?
How many electrons are shared in a double bond?
How many electrons are shared in a triple bond?
The strongest covalent bond is a
What do you add to the element name for the second element in a covalent compound
The greek prefixes are added in the names to show the number of atoms. Match the greek prefix with its number
