Explain why the radius increases in going from 3d to the 4d metals but the radius...
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? (h) 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...

Why is electron configuration for V [Ar]4s^2 3d^3 instead of [Ar]4s^2 4d^3 Is it not in the 4th row??? Thanks.
The Conductivity of metals decreases with increasing Temperature. However, The conductivity of semiconductors increases. Explain these two trends.
The reducing abilities of the first-row transition metals generally __________ going from left to right across the period. a. decrease b. increase c. stay the same d. none of these e. remain at 1.0 V the answer is A please explain it.
Explain why metals have high reflectivity, and why they appear a certain color.
Fe, Co, and Ni are ferromagnetic, whereas Ru, Ir, and Pt are diamagnetic. Explain why magnetic metals are found only among the 3d and 4f elements. Why are Sc and Ti, which are also 3d elements, diamagnetic?
“Ionic radius” is one of the more difficult trends as there is no distinct trend going across a period, only down a group. However, there are other smaller trends that are just as important. Compare the ions of Na, Mg, and Al. Fill in the following statement: “For _____________ ions in the same period, as the charge increases, the ionic radius _______________.” Explain this observation. Compare the ions of N, O, and F. Fill in the following statement: “For ______________...
34. Explain the general trend for atomic radius going across a period; to the right. 35. Explain the general trend in atomic radius going down a group.
Use the electron configurations of the alkali metals to explain why they tend to form 1+ ions.
