#Explanation#Part 1: Atomic Structure1-3. These questions involve drawing and labeling parts of an atom. As an AI, I am unable to physically draw. However, I can explain that protons are positively charged particles found in the nucleus of an atom, neutrons are neutral particles also found in the nucleus, and electrons are negatively charged particles that orbit the nucleus in energy levels or shells.4. The element drawn is Boron. 5. The identity of an element is determined by the number of protons in its nucleus, also known as its atomic number. In this case, the atom has 5 protons, so it is Boron, which has an atomic number of 5.Part 2: Periodic Table6. The periodic table notation typically includes the atomic number (number of protons), chemical symbol, and atomic mass (number of protons + neutrons). 7. The number of protons in an atom is equal to the atomic number, which is listed on the periodic table.8. The number of neutrons can be determined by subtracting the atomic number from the atomic mass number.9. In a neutral atom, the number of electrons is equal to the number of protons.Part 3: Atomic Calculations10. The chart involves calculations related to atomic structure. The atomic number is the number of protons, the mass number is the sum of protons and neutrons, and in a neutral atom, the number of electrons equals the number of protons.#Answer#Part 1: Atomic Structure4. Boron5. The number of protons determines the identity of an element. In this case, there are 5 protons, which corresponds to Boron.Part 2: Periodic Table7. The number of protons in an atom is equal to the atomic number.8. The number of neutrons is the atomic mass number minus the atomic number.9. In a neutral atom, the number of electrons equals the number of protons.Part 3: Atomic Calculations10. Here is the completed chart:\begin{array}{|c|c|c|c|c|c|}\hline\ Element\ &\ Atomic\ \#\ &\ Mass\ \#\ &\ \#\ of\ p\ \ \mathbf{p}^{+}\ \ &\ \ \#\ \ of\ \ n^{0}\ \ &\ \ \#\ \ of\ \ \mathrm{e}^{-}\ \ \\\hline\ Li\ &\ 3\ &\ 7\ &\ 3\ &\ 4\ &\ 3\ \\\hline\ P\ &\ 15\ &\ 31\ &\ 15\ &\ 16\ &\ 15\ \\\hline\ H\ &\ 1\ &\ 1\ &\ 1\ &\ 0\ &\ 1\ \\\hline\ Mn\ &\ 25\ &\ 55\ &\ 25\ &\ 30\ &\ 25\ \\\hline\ K\ &\ 19\ &\ 39\ &\ 19\ &\ 20\ &\ 19\ \\\hline\ Ag\ &\ 47\ &\ 108\ &\ 47\ &\ 61\ &\ 47\ \\\hline\ Cl\ &\ 17\ &\ 35\ &\ 17\ &\ 18\ &\ 17\ \\\hline\ Si\ &\ 14\ &\ 28\ &\ 14\ &\ 14\ &\ 14\ \\\hline\ W\ &\ 74\ &\ 184\ &\ 74\ &\ 110\ &\ 74\ \\\hline\ Ne\ &\ 10\ &\ 20\ &\ 10\ &\ 10\ &\ 10\ \\\hline\end{array}
