What is the transition metal with 78 electrons?
Platinum
Platinum (Pt) is a heavy white metal that has the atomic number 78 in the periodic table. It is a Transition metal in Group 10.
Which element is considered a transition metal?

How do you find transition metals?
Early transition metals are on the left side of the periodic table from group 3 to group 7. Late transition metals are on the right side of the d-block, from group 8 to 11 (and 12 if it is counted as transition metals).
Is scandium a transition metal?
A transition metal is one that forms one or more stable ions which have incompletely filled d orbitals. On the basis of this definition, scandium and zinc do not count as transition metals – even though they are members of the d block. Scandium has the electronic structure [Ar] 3d14s2.

Which element is a transition metal with 25 electrons?
Manganese
Manganese is a chemical element with symbol Mn and atomic number 25. Classified as a transition metal, Manganese is a solid at room temperature.
What is the name of the Group 8 elements on the periodic table?
Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
Is tellurium a transition metal?
Other elements sometimes included are the group 11 metals copper, silver and gold (which are usually considered to be transition metals); the group 12 metals zinc, cadmium and mercury (which are otherwise considered to be transition metals); and aluminium, germanium, arsenic, selenium, antimony, tellurium, and polonium …
Why is silver a transition metal?
However, in the +2 oxidation state, an electron is removed from the d-orbital. Thus, the d-orbital now becomes incomplete (4d9). Hence, it is a transition element.
How many electrons are there in a transition metal?
Transition metals are able to put more than eight electrons in the shell that is one in from the outermost shell. Think about argon (Ar). It has 18 electrons set up in a 2-8-8 order. Scandium (Sc) is only 3 spots away with 21 electrons, but it has a configuration of 2-8-9-2.
What are the valence orbitals of the first row transition metals?
In general, the first-row transition metals have a set of valence orbitals that include their #4s# and #3d#’s, but the number of valence electrons will vary.
What are the main group elements and transition metals?
The main group elements include the active metals in the two columns on the extreme left of the periodic table and the metals, semimetals, and nonmetals in the six columns on the far right. The transition metals are the metallic elements that serve as a bridge, or transition, between the two sides of the table.
What is the oxidation state of transition metals in chemistry?
For example, iron commonly carries a 3+ or 2+ oxidation state. Copper may have a 1+ or 2+ oxidation state. The positive oxidation state means the transition metals typically form ionic or partially ionic compounds. Atoms of these elements have low ionization energies.
