The element that best fits this is phosphorus. 2. B The peaks, in order, represent 1s, 2s, 2p, 3s, and 3p. 3. D The less ionization energy that is required to remove an electron, the more kinetic energy that electron will have after ejection. 4. D Valence electrons are those in the outermost energy level. In this case, that is the third level, which has five valence electrons in it (two in 3s and three in 3p). 5. D The ion has three more electrons than the neutral atom, meaning the overall repulsion will be greater.
By showing every step, or explaining what you’re doing in words, you ensure that you’ll get all the partial credit possible, even if you screw up a calculation. Include Units in All Your Calculations Scientists like units in calculations. Units make scientists feel secure. You’ll get points for including them and you may lose points for leaving them out. Remember Significant Figures You can lose 1 point per question if your answer is off by more than one significant figure. Without getting too bent out of shape about it, try to remember that a calculation is only as accurate as the least accurate number in it.
D This element has five peaks, meaning a total of five subshells. The final peak, which would be located in the 3p subshell, is slightly higher than the 3s peak to the left of it. A full 3s peak has two electrons, therefore there must be at least three electrons in the 3p subshell. The element that best fits this is phosphorus. 2. B The peaks, in order, represent 1s, 2s, 2p, 3s, and 3p. 3. D The less ionization energy that is required to remove an electron, the more kinetic energy that electron will have after ejection.
