Holt Modern Chemistry Chapter 6.1 Section Quiz

Ionic bonds form as a result of the electrostatic attraction between:

• Dipoles

• Electrons

• Ions

• Nuclei

A single covalent bond involves the sharing of:

• Only one electron

• Two electrons

• Three electrons

• A variable number of electrons which depends on the bonding atoms.

• Na and Cl

• O and Cl

• H and O

• Na and O

• None of the given answers

• K and N

• K and S

• N and Br

• S and Br

• None of the given answers

A measure of an atoms ability to attract electrons is:

• Electronegativity

• Polarization

• Ionization

• Electron Affinity

• Both polarization and ionization

Atoms that are bonded with an electronegativity difference of 0 to 0.3 are generally considered to be:

• Negatively charged compounds

• Non-polar covalent compounds

• Polar covalent compounds

• Ionic compounds

• Diatomic compounds

What is the apparent charge on the chlorine atom in the HCl molecule?

• +1

• -1

• 
• 

Atoms seldom exist as independent particles in nature because:

• as single particles, most atoms have low potential energy

• their electronegativity is much lower when they combine with other atoms

• atoms are more stable when they combine with other atoms

• neutral particles are very rare.

When an atom completely gives up its valence electrons to another atom, they form a bond that is considered to be:

• Purely ionic

• Partially ionic

• Polar-covalent

• Nonpolar-covalent

• Not a bond

You can estimate the degree to which a bond between two atoms is ionic or covalent by calculating the:

• distance between atoms nuclei

• difference in the atoms' electronegativities

• atoms' atomic radii

• number of atoms in the compound

• overall atomic mass
