Atomic Structure and Bonding

What is the Bohr atomic model?

• The Bohr atomic model is a type of chemical bond

• The Bohr atomic model is a type of radioactive decay

• The Bohr atomic model is a type of subatomic particle

• The Bohr atomic model is a description of the structure of an atom.

Explain the concept of energy levels in the Bohr atomic model.

• The Bohr model does not account for energy levels.

• Electrons are arranged in specific energy levels or orbits around the nucleus.

• Electrons are arranged randomly around the nucleus.

• Energy levels are determined by the number of protons in the nucleus.

How does the Bohr atomic model differ from the earlier atomic models?

• Random movement of electrons within the atom

• Quantized energy levels and orbits for electrons

• Continuous energy levels for electrons

• No specific orbits for electrons

What is a Lewis dot structure?

• A type of musical notation

• A method for calculating atomic mass

• A system for naming chemical compounds

• A diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons.

How do you determine the Lewis dot structure for an element?

• By looking at the element's position on the periodic table

• By counting the number of protons in the nucleus

• By determining the number of neutrons in the atom

• By knowing the number of valence electrons and following the rules for drawing the Lewis dot structure.

Explain the octet rule in covalent bonding.

• The octet rule states that atoms must have 8 electrons in their inner shell to form a covalent bond.

• Atoms tend to gain, lose, or share protons in order to have a full outer shell of 8 electrons.

• The octet rule only applies to ionic bonding, not covalent bonding.

• Atoms tend to gain, lose, or share electrons in order to have a full outer shell of 8 electrons.

Give an example of a molecule that follows the octet rule.

• Oxygen (O2)

• Carbon (C2)

• Hydrogen (H2)

• Nitrogen (N2)

What is ionic bonding?

• The type of bonding that involves the transfer of protons from one atom to another.

• The type of bonding that involves the attraction between positive and negative ions.

• The type of bonding that involves sharing of electrons between atoms.

• The type of bonding that involves the transfer of electrons from one atom to another.

How do atoms achieve stability through ionic bonding?

• By absorbing electrons from the environment to achieve stability.

• By sharing protons between atoms to form a stable bond.

• By releasing neutrons to create a stable atomic structure.

• By transferring electrons between atoms to form positively and negatively charged ions.

Compare and contrast covalent bonding and ionic bonding.

• Covalent bonding and ionic bonding both involve the transfer of electrons from one atom to another.

• Covalent bonding and ionic bonding are the same thing and can be used interchangeably.

• Covalent bonding involves the sharing of electrons between atoms, while ionic bonding involves the transfer of electrons from one atom to another.

• Covalent bonding involves the transfer of electrons from one atom to another, while ionic bonding involves the sharing of electrons between atoms.
