Kuster ~ Bonding ~ Intro

The strength of an atom’s attraction for the electrons in a chemical bond is the atom’s

• electronegativity

• ionization energy

• heat of reaction

• heat of formation

Which of these elements has the least attraction for electrons in a chemical bond?

• oxygen

• chlorine

• nitrogen

• fluorine

Based on Reference Table S, the atoms of which of these elements have the strongest attraction for electrons in a chemical bond?

• N

• Na

• P

• Pt

Based on electronegativity values, which type of elements tends to have the greatest attraction for electrons in a bond?

• metals

• noble gases

• metalloids

• nonmetals

An atom of argon (Ar) rarely bonds to an atom of another element because an argon atom has

• 8 valence electrons

• 2 electrons in the first shell

• 3 electron shells

• 22 neutrons

A solid substance is an excellent conductor of electricity. The chemical bonds in this substance are most likely

• ionic, because the valence electrons are shared between atoms

• ionic, because the valence electrons are mobile

• metallic, because the valence electrons are stationary

• metallic, because the valence electrons are mobile

An atom in the ground state has seven valence electrons. This atom could be an atom of which element?

• calcium (Ca)

• fluorine (F)

• oxygen (O)

• sodium (Na)

What is the total number of valence electrons in a sulfide ION in the ground state?

• 8

• 2

• 16

• 18

In which type of chemical reaction are electrons transferred?

• organic addition

• oxidation-reduction

• double replacement

• acid-base neutralization

An ionic bond can be formed when one or more electrons are

• equally shared by two atoms

• unequally shared by two atoms

• transferred from the nucleus of one atom to the nucleus of another atom

• transferred from the valence shell of one atom to the valence shell of another atom
