What metal is in the first series of transition metals?
Copper metal
Copper metal (with electronic configuration [Ar]3d104s1) in the first series of transition metals exhibits +1 oxidation state most frequently as it readily loses one electron (present in 4s orbital) to give stable 3d10 electronic configration.
Is the first transition metal in Period 6?

What are the 14 transition metals called?
Typically the elements of the post-transition metals include any metal in groups 13, 14, and 15 which are aluminum, gallium, indium, tin, thallium, lead, and bismuth. Polonium is often classified as a post-transition metal as well.
Where are transition metals found in the world?
Transition metals are found everywhere on Earth in various amounts. Most are not found in a pure substance, but rather in compounds buried in the Earth’s crust. This means that we must extract the metal from the compound in one of two ways.
What are the first transition series elements?
The first main transition series begins with either scandium (symbol Sc, atomic number 21) or titanium (symbol Ti, atomic number 22) and ends with zinc (symbol Zn, atomic number 30). The second series includes the elements yttrium (symbol Y, atomic number 39) to cadmium (symbol Cd, atomic number 48).
Which metal is in the first transition series 3d exhibits?
Cu
(a) Cu is the only metal in the first transition series (3d series) which shows+ 1 oxidation state most frequently. This is because the electronic configuration of Cu is 3d104s1 and after losing one electron it acquires cl stable 3d10 configuration.
Which period can you find helium *?
period 1
Helium is the second element on the periodic table. It is located in period 1 and group 18 or 8A on the righthand side of the table. This group contains the noble gases, which are the most chemically inert elements on the periodic table. Each He atom has two protons and usually two neutrons and two electrons.
What is period 7 on the periodic table?
Period 7 contains the actinides, which comprises plutonium (the naturally occurring element with the heaviest nucleus). All the elements of period 7 are radioactive.
What are the first 10 elements?
First 10 elements and their symbols:
- Hydrogen (H)
- Helium (He)
- Lithium (Li)
- Beryllium (Be)
- Boron (B)
- Carbon (C)
- Nitrogen (N)
- Oxygen (O)
What is the origin of the name transition metals?
The transition metals are the largest group of elements on the periodic table. They got their name because English chemist Charles Bury described a transition series of elements in 1921.
