Ionic Bonds

What type of bond is formed when electrons are transferred from one atom to another?

• Covalent bond

• Ionic bond

• Metallic bond

• Hydrogen bond

What determines the similar properties of elements within a group on the periodic table?

• The number of protons

• The number of valence electrons

• The atomic mass

• The number of neutrons

What role do valence electrons play in atoms?

• They determine the atomic mass

• They are involved in the formation of chemical bonds

• They define the number of protons

• They are responsible for the atomic number

What is a chemical bond?

• A type of atomic nucleus

• The force that holds two atoms together

• A form of energy release

• The number of electrons in an atom

How can chemical bonds form between atoms?

• By the attraction between the positive nucleus of one atom and the negative electrons of another atom.

• By the repulsion between the positive nucleus of one atom and the positive nucleus of another atom.

• By the attraction between the negative electrons of one atom and the negative electrons of another atom.

• By the repulsion between the negative electrons of one atom and the positive nucleus of another atom.

What is formed when atoms gain or lose valence electrons to achieve a stable octet electron configuration?

• Molecules

• Ions

• Isotopes

• Compounds

What charge do ions have?

• Neutral

• Positive or negative

• Only positive

• Only negative

What remains unchanged in the nucleus during ion formation?

• Number of electrons

• Number of protons

• Number of neutrons

• Number of atoms

What is the octet rule in chemistry?

• Atoms tend to gain, lose, or share electrons to acquire 8 valence electrons.

• Atoms always lose electrons to become stable.

• Atoms do not interact with each other.

• Atoms always gain electrons to become stable.

Why are noble gases generally unreactive?

• They have a full outer energy level.

• They need more electrons to be stable.

• They are always in a liquid state.

• They have an incomplete outer energy level.
