Part A Recall all the models you described in task 1. Think about the results each model would predict for the experiment with hydrogen gas. Which models of the atom does the experimental evidence support? Explain why these models are compatible with the experimental results. Part B Which models of the atom in task 1 are not supported by the results of the hydrogen gas experiment? For each of these models, explain the experimental results that the model would predict. Models in task 1:  - Dalton’s Atomic Model - Thomson’s Atomic Model - Rutherford’s Atomic Model - Bohr’s Atomic Model

Which chemical reactions are not possible according to Dalton's atomic theory? CC14 → CH4 N₂ + 3H₂ 2H₂ + O₂ 2 2NH3 2 H₂O + Au

Need help with this pjhysics theoretical question: The most surprising evidence from Rutherford’s experiment that disproved Thomson’s model was that:     the alpha particles were able to pass through the gold foil   most of the alpha particles were deflected by less than one degree   a few alpha particles were scattered through very large angles   the scattering was less random than expected

ng tu another question will save this response. stion 2 Which part(s) of Dalton's atomic theory were demonstrated to be incomplete a. Matter is made of indivisible atoms O b. Atoms are made of protons, neutrons, and electrons C. Each atom is identical to others of the same element d. Atoms of a specific element are different from atoms of all other element e. Some atoms of the same elements can combine in different whole numbe Of. Atoms combine in whole number ratios to form compounds

2. Which of the following best describes an element? a. A neutral substance consisting of a cation and an anion b. A substance consisting of two non-metals C. A substance consisting only of atoms having the same nur of protons. d. A substance that can only be found as a solid e. A substance consisting only of atoms having the same num of neutrons O a O b O c dl

Atomic Theory & Scientists 1. Write the letter of each sentence that is true about Dalton's atomic theory. a. All elements are composed of tiny, indivisible particles called atoms. An element is composed of several types of atoms. b. c. Atoms of different elements can physically mix together, or can chemically combine in simple, whole-number ratios to form compounds. d. Chemical reactions occur when atoms are separated, joined or rearranged; however, atoms of one element are never changed into atoms of another element by a chemical reaction.

Which subatomic particle is transmitted through electric current? A. proton B. electron C. electron D. nucleus

Which of John Dalton’s theories given below were found to be INCORRECT?1. the atoms of elements remain unchanged when they combine to form chemical compounds2. the atom is the smallest unit of matter that retains its chemical identity3. all atoms of the same element are identical4. the atom cannot be divided into any smaller unit of massA) 2 and 3 D) 1, 2, and 3B) 3 and 4 E) all four were found to be correct C) 1,3,and4

6. Who discovered the nucleus of the atom? A. Dalton B. Rutherford C. Millikan D. Thomson 7. The five spheres below represent Se, Se2-, O, H, and S, not necessarily in that order. 37 pm 72 pm 100 pm 114 pm 196 pm Which answer correctly orders all five species from smallest to largest? A. O х"(g) + e B. X*(g) → X*(aq) С. Х(g) + e -> X (з) D. X*(g) + e→ X(g) 9. Which of the following compounds are insoluble? A. Pbl2 В. CaSO4 С. CSCI D. Nazs E. Both A and B 10. Assign oxidation numbers to the chlorine atom in each of the following compounds: Cl2, HCI, ClO3, CIF3, PCI3 А. О, —1, +6, +3, -1 В. О, —1, +5, +3, -3 С. 0, —1, +5, +3, —1 D. 0, -1, +3, +3, –1

If you wanted to make an accurate scale model of the hydro- gen atom and decided that the nucleus would have a diameter of 1 mm, what would be the diameter of the entire model?   I understand the answer however wouldnt the end result be much smaller than 106 mm since we are only find the diameter of the nucleus? Is the 106 always used in these types of equations? What would be used in this equation for say a carbon atom?
