How does the atomic theory of matter explain the law of conservation of mass and the law of constant composition?
Each atom of a particular element has a constant (average) weight, and in chemical reactions, the numbers and types of atoms in the reactants must be the same as the numbers and types of atoms in the products. This explains the law of the conservation of mass. Each molecule of a compound or polyatomic element is composed of a fixed number of one or more particular kinds of atoms; this explains the law of constant composition.

Each element has its own characteristic atom in which a. the atomic weight is constant b. the atomic number is constant c. the mass number is constant?
b. the atomic number is constant. The mass number is not constant because there are isotopes of an element that have the same number of protons but different number of neutrons. Likewise, there are isotopes of the same element with different atomic weights.
What is the term for a symbolic method of expressing the composition of an atomic nucleus?
The term is nuclear notation or nuclear symbol. It is a shorthand way to represent the composition of an atomic nucleus, indicating the chemical element symbol, mass number, and atomic number of a particular nucleus.
Would the atomic emission spectrum for each sample change if you repeated the procedure?
No, the atomic emission spectrum for a specific element will not change if you repeat the procedure under the same conditions. Each element has a unique set of energy levels, so the spectral lines emitted are constant.
Why is atomic structure important to biologist?
Atomic structure is crucial to biologists because it underpins the composition and behavior of biological molecules, including proteins, lipids, carbohydrates, and nucleic acids. Understanding atomic interactions, such as covalent and ionic bonds, helps explain how these molecules form and function in living organisms. Additionally, knowledge of atomic structure is essential for studying processes like enzyme activity, cellular respiration, and genetic mechanisms, all of which are fundamental to life. Overall, atomic structure provides a foundation for exploring the molecular basis of biology.

What was John Dalton contributes in atomic theory?
It explained law of conservation of mass and law of constant proportion and laid foundation to atomic physics n chemistry...
What benefit did chemists derive from Dalton's atomic theory?
Chemists benefited from Dalton's atomic theory by gaining a better understanding of the composition and behavior of matter at the atomic level. This theory provided a foundation for modern chemistry and helped explain various chemical reactions and properties of elements.
When did Dalton publish law of constant composition?
Joseph Proust, based on experiments conducted at the end of the 18th Century claimed that elements combined in constant proportions. Dalton's atomic theory, (1903) built on this earlier work and put it into a theoretic framework.
Each element has its own characteristic atom in which a. the atomic weight is constant b. the atomic number is constant c. the mass number is constant?
b. the atomic number is constant. The mass number is not constant because there are isotopes of an element that have the same number of protons but different number of neutrons. Likewise, there are isotopes of the same element with different atomic weights.
How does Dalton atomic theory explain the law of conservation of mass?
Dalton doesn't explain the law of conservation of mass.
Is atomic number constant?
It is constant for elements. IT depends on number of protons that atom has.
What does the effect of beta decay on the composition of a nucleus?
Beta decay can change the composition of a nucleus by transforming a neutron into a proton, resulting in the emission of a beta particle (electron) and an antineutrino. This process increases the atomic number of the nucleus while keeping the mass number constant, resulting in a different element.
How do you explain what does the atomic number stands for?
The atomic number is the number of protons in the atom.
What is the term for a symbolic method of expressing the composition of an atomic nucleus?
The term is nuclear notation or nuclear symbol. It is a shorthand way to represent the composition of an atomic nucleus, indicating the chemical element symbol, mass number, and atomic number of a particular nucleus.
What is the plancks constant in a very simple way?
Planck's constant is a fundamental constant in physics that relates the energy of a photon to its frequency. It is denoted by the symbol ( h ) and has a value of approximately ( 6.626 \times 10^{-34} ) joule-seconds. This constant is crucial in quantum mechanics, as it helps explain how energy is quantized at the atomic and subatomic levels. Essentially, it shows that energy comes in discrete packets, or "quanta."
Why do we need atoms?
According to modern Periodic Table Atomic numbers are the fundamentals in order to explain the properties of an atom.One thing more and that is the concept of isotopes also make the atomic masses less strong to explain atomic properties which has no effect on atomic numbers.
