Question

name _ id _ subject chemistry period _ date _ atomic structure unit - writing prompt in this past unit, you have learned that atoms are made up of three subatomic particles and how those particles are arranged in the atom. we learned of the different models of the atoms that were developed. the models help us have an understand how the atoms look. as new discoveries were made, old models were replaced by new models, until our current quantum model. think about how the subparticles are arranged inside atoms and how the arrangement changed with each model. explain what is an atom and how models of the atom are used to explain the contents of an atom. be sure to mention that models change as scientists make discoveries. in your response, some things you can discuss are: o define what is an atom o state each subatomic particle and its charge o state which particles are located in the nucleus and the overall charge of the nucleus o state how the bohr model showed the location of the electrons o state similarities in the location of electrons in the bohr model and quantum model o state differences in the location of electrons in the bohr model and quantum model be sure to consider the completeness of your response, supporting details, and accurate use of terms. use at least five properly written sentences.

Explanation:

An atom is the basic unit of matter. Subatomic particles include protons (positively - charged), neutrons (neutral), and electrons (negatively - charged). Protons and neutrons are in the nucleus, giving it a positive charge. The Bohr Model showed electrons in fixed orbits around the nucleus. Both the Bohr and Quantum Models deal with electron location, but the Quantum Model describes electrons in probability clouds rather than fixed orbits. As new scientific discoveries are made, atomic models change to better explain atomic contents.

Answer:

An atom is the fundamental building block of matter. Subatomic particles are protons (charge +1), neutrons (charge 0), and electrons (charge - 1). Protons and neutrons are located in the nucleus, and the nucleus has an overall positive charge due to the protons. The Bohr Model depicted electrons in circular orbits around the nucleus. In both the Bohr and Quantum Models, electrons are outside the nucleus. However, in the Bohr Model, electrons have fixed orbits, while in the Quantum Model, electrons exist in probability regions called orbitals. Atomic models are used to represent and understand the composition and behavior of atoms, and they evolve as scientific knowledge advances.
