Unit 2 Thou shall not forget

Front

What are covalent bonds?

Back

Covalent bonds are formed between two nonmetals sharing electrons.

Front

How are ionic bonds formed?

Back

Ionic bonds are formed when a metal transfers electrons to a nonmetal and the opposite charges attract.

Front

What happens as the electronegativity difference between two atoms increases?

Back

The greater the electronegativity difference between 2 atoms, the more polar the bond becomes.

Front

What are the products of combustion reactions?

Back

Combustion reactions make CO2 and H2O.

Front

How many bonds does carbon make in a compound?

Back

Carbon makes a total of 4 bonds in a compound.

Front

What are the bond angles for different domains?

Back

4 domains = 109.5°, 3 domains = 120°, 2 domains = 180°.

Front

What are the hybrid orbitals for different domains?

Back

Front

What is the difference between asymmetrical and symmetrical molecules?

Back

Front

What types of bonds are present in single, double, and triple bonds?

Back

Single bond = sigma, double bond = sigma + pi bond, triple bond = sigma + 2 pi bonds.

Front

What is lattice energy?

Back

Lattice energy is the energy to break an ionic bond in a compound. It increases as the ion’s charge increases and decreases as the radii of the ions increase.
