Transition metals can be distinguished from main-group metals by the fact that transition metals have higher...
For the main group elements, atomic size increases down the
group. For the transition metals, how does the atomic size change
from the 4d series to 5d series? What is the factor that causes the
difference between these two types of elements?

Choose one of the transition or inner transition metals from the periodic table. Discuss why your transition metal and their compounds display a variety of color. Be sure to include in your discussion, important oxidation states, the electron configuration and how the d-electrons are involved. How can you include the electromagnetic spectrum and the nature of light into your discussion? How is energy and wavelength related? Use your knowledge of the emission and absorption of light. HELP!!!!!!
Transition metals generally do not follow the same periodic trends as main group elements. Based on your results, does the activity of a main group (s and p blocks) metal seem to increase or decrease as you move from left to right across a period? 2. 15

CaH2 H2S SiH4 I only II only I and II I and III II and III Based on the following options, select the substance with hydrogen in the +1 oxidation state. KH CH4 H2 AlH3 SrH2 Which of these substances is being...
Period four transition metals have higher densities dense (e.g., Cu, d = 8.96 g/cm) compared to period four group 1A metals (e.g., K, d = 0.86 g/cm'). Explain.
1 . Describe the chemistry of the group 14 elements with reference to (i) decreasing catenation, (ii) increased metallic behaviour on descending the group and (iii) the relative stability of the +2 and +4 oxidation states. 2. Discuss with relevant examples how the stability of the +2 oxidation state varies across the 1st row transition metals. Describe with relevant examples the general types of ligands that can stabilise higher oxidation states in metal complexes. 3. Discuss in detail the spectroscopic...
8-7 Why is the first ionization energy for phosphorous higher than the first ionization energy for sulfur even though the general trend in the periodic table is to have the ionization energy increase as you go from left to right on the table. 8-8 The three most common oxidation states for Fe are +2, +3 and +6 what are the most likely electronic configurations for these three ions? 8-9 Why do transition metals have magnetic properties? 8-10 Just looking at...

general chemistry Hi, Good morning. I want to tell you that my score is now 70 out of 80 and I want to get the full score of 20/20 in my final test. Can you do the answer only with the symbols A, B, C, D. Thank you, I do not want to explain only the answer because I have no time other than 50 minutes. Rusting of iron occurs due to a. hydrogenation b. oxidation c. reduction d. sublimation...
