Bonding Test

Electrons involved in bonding between atoms are

• valence electrons

• inside the nucleus

• closest to the nucleus

• positively charged

Each family in the periodic table has its own characteristic properties based on the number of

• valence electrons

• neutrons

• protons

• ions

What's the greatest number of valence electrons an atom can have?

• 3

• 3

• 8

• 12

If atoms of a halogen nonmetal (Column 17) gain one electron, the atoms then have

• no valence electrons

• 7 valence electrons

• 8 valence electrons

• 17 valence electrons

When an atom loses an electron, it becomes a

• positive ion

• negative ion

• neutral ion

• neutral atom

An ionic bond is the attraction between

• similarly charged ions

• oppositely charged ions

• neutral ions

• neutral atoms

Ionic compounds are electrically

• charged

• positive

• negative

• neutral

A chemical bond formed when two atoms share electrons is called a(n)

• ionic bond

• covalent bond

• polyatomic bond

• crystal bond

What is a double bond?

• a bond between to atoms

• one pair of electrons shared between two atoms

• two pairs of electrons shared between two atoms

• two pairs of electrons shared between four atoms

A covalent bond in which electrons are shared unequally is

• polar

• a double bond

• ionic

• polyatomic
