What are the example of inner transition element?
The inner transitional metals contain 2 main groups, the lanthanide series, and the actinide series (f block elements). The lanthanide series include the 14 elements that proceed lanthanum (atomic number 57) from atomic numbers 58 to 71. Their electron configuration include the 4f and 5d energy levels. Because of the closeness of those two levels, there is considerable uncertainty in some electron configuration assignments. The actinide series include the 14 elements that proceed actinium (atomic number 89) from atomic numbers 90 to 103. The electron configurations of the actinides are even more uncertain than the lanthanides because the closeness of the energy levels and because the nuclei are unstable to radioactive decay. Only minute amounts of some elements are obtained because of their instability. All of the actinides are unstable with respect to alpha emission. The later members tend to undergo spontaneous fission, a fact which limits the number of elements possible.
Is the inner lithium shell full?
Yes, Lithium has the Atomic Number 3, therefore has 3 electrons. The inner 'shell' of electrons only needs 2 electrons to be full. The Li+ ion also has a full inner shell.
What are the layers of the earth in order from lowest pressure to greatest pressure?
The layers of the Earth in order from lowest pressure to greatest pressure are the crust, mantle, outer core, and inner core. The inner core experiences the highest pressure due to the weight of all the layers above it.
How many core electrons in nitrogen?
Nitrogen has 2 core electrons and 5 valence electrons. If you remember, nitrogen has an atomic number of 7. When an atom is neutral it has an equal number of protons and electrons. Therfore, the overal number of electrons is 7. The definition of core electrons is, electrons in their most inner shell, On the other hand valence electrons are electrons in the outermostshell. When looking at a periodic table you see that there is a total# of 5 valence electrons. In order to figure out the core number you subtract the total number of electrons(atomic #) - Valence # of electrons. I hope this helped :)
What of the layers of the earth in order from lowest temperature to highest?
The layers of the Earth in order from lowest temperature to highest are the inner core, outer core, mantle, and crust. The inner core is the hottest layer, with temperatures reaching up to 9,000 degrees Fahrenheit, while the crust is the coolest layer, with temperatures varying between 32 and 212 degrees Fahrenheit.
Which inner transition metal has an atomic mass of 167.26?
The inner transition metal with an atomic mass of approximately 167.26 is Erbium (symbol: Er, atomic number: 68).
What is the name of the element with the atomic numer91?
The element with atomic number of 91 is protactinium, Pa. It is an inner transition metal.
Is americium a transition metal?
Americium is considered an inner transition metal.
What inner transition metal has an atomic mass of 167.26?
This chemical element is erbium.
The number of inner transition elements is greater than the number of transition elements?
This statement is incorrect. Inner transition elements are a subset of transition elements, and they refer specifically to the lanthanides and actinides series. There are more transition elements (d-block elements) than inner transition elements in the periodic table.
Is found in group 3 and period 6 of the modern periodic table?
The element is an inner transition metal called lanthanum, with the atomic number 57.
What is the name of two series of inner Transition elements?
The lanthanide and actinide series. Trait of lanthanide: Lanthanum, element 57. Trait of actinide: actinium, element 89.
Is neodymium an element a compound a mixture or not matter?
Neodymium (Nd) is an inner transition metal with atomic number 60 on the periodic table.
What is the element name for mariecurie?
The element named for Marie Curie and her husband Pierre Curie is curium. Its atomic number is 96, and its symbol is Cm. It is an inner transition metal in the Actinide series.
Is nickel an inner transition element?
Nickel is not an inner transition element.
Subtracting four from the period number of an inner-transition metal will indicate the number of shells?
Subtracting four from the period number of an inner-transition metal will give you the number of shells in its electron configuration. This is because the period number corresponds to the energy level where the outermost electrons are located. Inner-transition metals are located in the f-block of the periodic table.
What is an inner transition metal with fourteen 4f electrons?
An inner transition metal with fourteen 4f electrons is Lutetium (Lu), which has the atomic number 71. Lutetium is part of the lanthanide series and is the last element in that series, completing the filling of the 4f subshell. It is known for its high density and is used in various applications, including catalysts and phosphors.
