please help

Wiki says about Dalton:

The main points of Dalton's atomic theory were:

Elements are made of extremely small particles called atoms.
Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass, and other properties.
Atoms cannot be subdivided, created, or destroyed.
Atoms of different elements combine in simple whole-number ratios to form chemical compounds.
In chemical reactions, atoms are combined, separated, or rearranged.

p orbital 2*3 = 6

so c and b

Yes, I would go with c and b

whoops, I saw the p but not the px

Only 2 electrons can fit in the p orbital pointing in the x direction. You can also have 2 py electrons and 2 pz electrons.

whoops, I saw the p but not the px

Only 2 electrons can fit in the p orbital pointing in the x direction. You can also have 2 py electrons and 2 pz electrons.

thank you

To determine the contributions of John Dalton to atomic theory and the maximum number of electrons that the px atomic orbital subtype can hold, we can break down the information and analyze each question independently.

For the first question, let's review the answer choices given in order to determine which option best describes John Dalton's contribution to atomic theory:

1. He discovered the nucleus.
2. He gave future scientists a foundation for understanding how electrons move.
3. He gave future scientists a foundation for understanding how atoms make up matter.
4. He discovered the electrons.

To find the correct answer, we need to understand John Dalton's contributions to atomic theory. John Dalton was an English chemist in the 18th century known for his atomic theory. According to Dalton's atomic theory, atoms are indivisible and indestructible particles that combine in specific ratios to form compounds. Based on this understanding, we can eliminate options 1 and 4 because Dalton did not discover the nucleus or the electrons.

Now, let's review options 2 and 3. Dalton's main contribution was the concept that atoms make up matter and that they combine in specific ratios to form compounds. This laid the foundation for future scientists to understand how atoms make up matter, so option 3, "he gave future scientists a foundation for understanding how atoms make up matter," is the most accurate choice and best describes Dalton's contribution to atomic theory.

Now, let's move on to the second question about the maximum number of electrons that the px atomic orbital subtype can hold. An atomic orbital refers to the region around an atomic nucleus where an electron is likely to be found. The "p" in the px atomic orbital subtype refers to the type of orbital, and it is associated with the shape of a dumbbell.

To determine the maximum number of electrons that the px atomic orbital subtype can hold, we need to consider the number of sub-orbitals within the px orbital and the maximum number of electrons each sub-orbital can hold.

Each px orbital consists of one sub-orbital, and each sub-orbital can hold a maximum of two electrons due to the Pauli exclusion principle. Therefore, the correct answer is option "a maximum of 2 electrons," as a px atomic orbital subtype can hold a maximum of 2 electrons.

I hope this explanation helps you understand the concepts and reasoning behind finding the answers to your questions.
