Fundamental Concepts of Atomic Structure and Chemical Laws Quiz

Protons carry a positive charge.

The atomic number of carbon is 6, which signifies the number of protons in its nucleus.

The unit of atomic mass is expressed in Daltons.

An atom is the smallest unit of an element that still retains its properties.

The number of electrons in the outermost shell of an atom is called valence electrons.

Dmitri Mendeleev proposed the first periodic table.

Avogadro's number represents the number of atoms or molecules in one mole of a substance.

The mass number of an atom is the sum of its protons and neutrons.

Antoine Lavoisier formulated the law of conservation of mass, which states that mass is neither created nor destroyed in chemical reactions.

Erwin Schrödinger proposed the quantum mechanical model of the atom.

J.J. Thomson discovered the electron through his experiments with cathode rays.

Dalton's Law of Partial Pressures states that the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of each individual gas.

The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of quantum numbers.
