Dalton's Atomic Theory Quiz

Who proposed the Dalton's atomic theory?

• Isaac Newton

• John Dalton

• Albert Einstein

• Marie Curie

What is the main postulate of Dalton's atomic theory?

• Atoms are divisible and destructible particles.

• Atoms are indivisible and indestructible particles.

• Atoms are made up of protons, neutrons, and electrons.

• Atoms can be created or destroyed in chemical reactions.

What is the law of multiple proportions?

• The law of multiple proportions states that the ratio of the masses of elements in different compounds can be expressed in small whole numbers.

• The law of multiple proportions states that the ratio of the masses of elements in different compounds can be expressed in fractions.

• The law of multiple proportions states that the ratio of the masses of elements in different compounds can be expressed in decimals.

• The law of multiple proportions states that the ratio of the masses of elements in different compounds can be expressed in irrational numbers.

According to the law of definite proportions, what is the relationship between the mass of elements in a compound?

• The mass of elements in a compound is random.

• The mass of elements in a compound is inversely proportional.

• The mass of elements in a compound is in a constant ratio.

• The mass of elements in a compound is always equal.

What is Dalton's atomic model also known as?

• billiard ball model

• solar system model

• electron cloud model

• plum pudding model

What are the three main points of Dalton's atomic theory?

• 3. Atoms can be created, destroyed, or divided into smaller particles in chemical reactions.

• 1. All matter is made up of tiny particles called molecules.

• 2. Atoms of the same element have different properties.

• 1. All matter is made up of tiny particles called atoms. 2. Atoms of the same element are identical in size, mass, and other properties, while atoms of different elements are different. 3. Atoms cannot be created, destroyed, or divided into smaller particles in chemical reactions.

What is the significance of Dalton's atomic theory in the development of modern atomic theory?

• Dalton's atomic theory provided the foundation for the development of modern atomic theory.

• Dalton's atomic theory was only relevant in the early stages of atomic theory.

• Dalton's atomic theory was disproven and replaced by modern atomic theory.

• Dalton's atomic theory had no significance in the development of modern atomic theory.

What is the difference between Dalton's atomic theory and Thomson's atomic theory?

• Dalton's atomic theory explained the concept of isotopes, while Thomson's atomic theory did not.

• Dalton's atomic theory proposed that atoms are composed of positive and negative charges, while Thomson's atomic theory did not.

• The main difference between Dalton's atomic theory and Thomson's atomic theory is the concept of the structure of the atom. Dalton believed in the indivisibility of atoms, while Thomson proposed the existence of subatomic particles within the atom.

• Dalton's atomic theory focused on the existence of electrons, while Thomson's atomic theory did not.

What are the limitations of Dalton's atomic theory?

• Dalton's atomic theory is outdated and no longer applicable in modern science.

• Dalton's atomic theory fails to account for the existence of subatomic particles.

• Dalton's atomic theory does not explain the behavior of gases.

• The limitations of Dalton's atomic theory include the assumption of indivisible and indestructible atoms, failure to account for isotopes and atomic mass, inability to explain chemical reactions, and lack of knowledge about subatomic particles.

Explain the concept of atomic mass according to Dalton's atomic theory.

• Atomic mass is the mass of an atom relative to the mass of an oxygen atom.

• Atomic mass is the mass of an atom relative to the mass of a hydrogen atom.

• Atomic mass is the mass of an atom relative to the mass of a carbon atom.

• Atomic mass is the mass of an atom relative to the mass of a helium atom.
