this is a question on my homework too! i don't know the answer though :/
Valence electrons
Before Niels Bohr's model, discoveries such as Max Planck's quantization of energy and Albert Einstein's explanation of the photoelectric effect helped pave the way for understanding the behavior of atoms. Additionally, Ernest Rutherford's nuclear model of the atom, which proposed a dense nucleus surrounded by orbiting electrons, was another key advance that influenced Bohr's model.
The "Atomic Number" is the number of protons in the nucleus of any atom.
Rutherford's nuclear model of the atom introduced several key strengths, including the identification of a dense, positively charged nucleus at the center of the atom, which provided a clearer understanding of atomic structure. This model effectively explained the results of the gold foil experiment, where most alpha particles passed through, indicating that atoms are mostly empty space. Additionally, it laid the groundwork for future atomic theories, paving the way for the development of quantum mechanics and the Bohr model. Overall, Rutherford's model significantly advanced the field of atomic physics by challenging earlier models and highlighting the importance of the nucleus.
Yes, an atom's mass is primarily concentrated in its nucleus, which is located in the center of the atom. The nucleus is made up of protons and neutrons, which are much more massive than the surrounding electrons. While electrons contribute to the overall size of the atom, they have negligible mass compared to the nucleus. Therefore, the nucleus is the key component that determines the atom's mass.
im awesome!

The main discoveries from the most recent customer review survey.
Zoology has made numerous discoveries, including the identification of new species, advancements in understanding animal behavior, and breakthroughs in genetics and evolutionary studies. Researchers have also contributed to conservation efforts by discovering key habitats and creating strategies for species preservation.
The two key discoveries during the Agricultural Revolution were the development of agriculture and the domestication of animals. These innovations allowed humans to shift from a nomadic lifestyle to settled communities, leading to the growth of civilizations.
The key difference between amine and amide functional groups in organic chemistry is that amines contain a nitrogen atom bonded to one or more carbon atoms, while amides contain a nitrogen atom bonded to a carbonyl carbon atom.
One of the key discoveries discussed in Principia by Isaac Newton is the law of universal gravitation, which describes the attraction between two objects with mass. Newton formulated this law to explain the motion of celestial bodies such as planets around the Sun.
