Types of bonds CrashCourse Interactive Video

• What is the type of bonding we learned about first?

• • Ionic bonding - where electrons are transferred

• • Ionic bonding - where protons are transferred

• • Ionic bonding - where electrons are destroyed

• trick question atoms don't bond

Why do atoms form bonds

• • For fun - it's boring being an atom

• • To reduce their overall energy

• • To be difficult

• • To gain electrons

What attracts the electrons from the atom on the left?

• • The electrons from the atom on the right

• • The protons from the atom on the right

• • The neutrons from the atom on the right

• • The neutrons from the atom on the left

Why don't the atoms get too close?

• • The neutrons from each atom repel each other

• • The electrons from each atom repel each other

• • The protons from each atom repel each other

• They actually smash together

What is the big idea this graph shows?

• • There is an ideal distance between atoms in a bond

• • Chlorine bonds are 0.00199 nm wide.

• • Energy in atoms stabilizes as they get further apart.

What makes Cl-Cl a covalent bond?

• • Electrons are released from both atoms

• • Cl steals an electron from the other atom

• • The atoms share a pair of electrons

• the atoms share neutrons

In a covalent bond, a bond is formed by atoms ________________ electrons.

• • transferring

• • sharing

Which atom(s) is pulling the electrons harder?

• • Hydrogen - because it has lower electronegativity

• • Oxygen - because it has higher electronegativity 

• • Oxygen - because it has lower electronegativity

• • Hydrogen - because it has higher electronegativity 

How is this different than a normal covalent bond?

• • Electrons are not shared

• • One of the atoms is an ion

• • Electrons are shared, but they aren't shared evenly

Which type of bond will Hydrogen and Sulfur form?

• • Polar covalent - because the electronegativities are very different 

• • Nonpolar covalent - because the electronegativities are very similar 

• • Nonpolar covalent - because the electronegativities are very different. 

• • Polar covalent - because the electronegativities are very similar.

• • Ionic - because they transfer electrons
