Decide whether these proposed Lewis structures are reasonable. proposed Lewis structure 10-C-6: C—0: :C=0: H-CIN Is the proposed Lewis structure reasonable? Yes. No, it has the wrong number of valence electrons. The correct number is: 0 No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* Yes. No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* 0 Yes. No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* * If two or more atoms of the same element don't satisfy the octet rule, just enter the chemical symbol as many times as necessary. For example, if two oxygen atoms don't satisfy the octet rule, enter "O,0". X Ś

First, show the formal charge on each atom of each ion, then choose which structure is preferred. :C=N=ö: The formal charge on C is 2 + The formal charge on N is +1 + The formal charge on O is o + . EN-C=0: The formal charge on N is -2 : The formal charge on C is 0 : The formal charge on O is +1 : The preferred structure is the bottom + one.

1 What is the total number of valence electrons in the Lewis structure of BrO4"? electrons 2 Draw a Lewis structure for BrO4 • Do not include overall ion charges or formal charges in your drawing. • If the species contains oxygen, do not draw double bonds to oxygen unless they are needed in order for the central atom to obey the octet rule. 0- Y **** O.

Please refer to the example image to answer. You must use CER, claim-evidence-reasoning. Make sure that your answer is CLEAR and explained well. Claim is your answer to the question. Evidence is from the image and reasoning is your explanation.  Proper evidence for all Lewis structures include: Most electronegative atom must be in the center. Octet of electrons surrounding each atom. Total number of electrons depicted equals same total number of valence electrons from each participating atom. Make sure to refer to the example image because it shows the correct Lewis structures. The question you're answering is about the students drawing of CH20.

Answer the questions in the table below about the shape of the chlorine trifluoride (ClF,) molecule. How many electron groups are around the central chlorine atom? Note: one "electron group" means one lone pair, one single bond, one double bond, or one triple bond. What phrase best describes the arrangement of these electron groups around the central chlorine atom? (You may need to use the scrollbar to see all the choices.) |(choose one)

Photoelectron spectroscopy applies the principle of the photoelectric effect to study orbital energies of atoms and molecules. High-energy radiation (usually UV or X-ray) is absorbed by a sample and an electron is ejected. The orbital energy can be calculated from the known energy of the radiation and the measured energy of the electron lost. The following energy differences were determined for several electron transitions: ΔE2 →1 = 4.098 ×10−17 J ΔE3 →1 = 4.854 × 10−17 JΔE5 → 1 = 5.242 ×10−17 J  ΔE4 → 2 = 1.024 ×10−17 J Calculate the energy change and the wavelength of a photon emitted in the following transitions. Enter your answers in scientific notation. Use 6.626 ×10−34 J·s for Planck's constant. (a) Level 3 to 2: ______J ______m (b) Level 4 to 1: _____J_____ m (c) Level 5 to 4: _____J _____m

Draw three resonance structures for CS,. This species has its three atoms bonded sequentially in the following fashion: S-C-S. Draw your resonance structures so that the atoms in them are bonded together in this order. Select the most important resonance structure for this species based on the formal charges on the atoms of the three resonance structures you have drawn. Select the choices from below which make the statements true about this (most important) resonance structure. (a) The leftmost bond (between S and C) is a single v bond. (b) The rightmost bond (between C and S) is a single v bond. (c) The formal charge on the leftmost (S) atom is -Select-v (d) The formal charge on the central (C) atom is -Select---v (e) The formal charge on the rightmost (S) atom is Select-v (f) The number of nonbonding pairs (lone pairs) of electrons in the leftmost (S) atom is Select-v pairs. (g) The number of nonbonding (lone) pairs of electrons in the rightmost (S) atom is -Select-- v pairs.
