John Dalton was an English scientist who lived from 1766 to 1844. Dalton's significant contributions to science include his postulates of atomic theory. Later findings supported much of what he proposed in the postulates, which now help form the
foundation of modern atomic theory.

Identify the statements that present a concept contained in Dalton's postulates of atomic theory. (one or more than one)

A) Electrons orbit the nucleus of an atom, composed of protons and neutrons.
B)All atoms of a given element possess the same
physical and chemical properties.
C) Atoms of different elements combine in simple whole number ratios to produce compounds.
D) The total pressure in a mixture of gases is equal to the sum of the partial pressures of the individual gases.
E) Particles, such as atoms, move at a speed proportional to their kinetic energy.

The statements related to Dalton's atomic theory are:

All atoms of a given element possess the same  physical and chemical properties.

Atoms of different elements combine in simple whole-number ratios to produce compounds.

Explanation:

The postulates of Daltons' atomic theory were:

So, from this, we can conclude that out of the given statements the statements related to Dalton's atomic theory are:

All atoms of a given element possess the same  physical and chemical properties.

Atoms of different elements combine in simple whole-number ratios to produce compounds.

These are the statements which were apart of Dalton's theory:

B (All atoms of a given element possess the same physical and chemical properties.)

C (Atoms of different elements combine in simple whole number ratios to produce compounds.)

These are the statements that are not apart of Dalton's theory:

A; the electron was discovered by JJ Thompson.

D; that wasn't a part of Dalton's theory.

E; movement of particles was not a part of his theory.

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
