The (loosely defined) transition metals are the 40 chemical elements 21 to 30, 39 to 48, 71 to 80, and 103 to 112. The name transition comes from their position in the Periodic Table of elements.
In each of the four periods in which they occur, these elements represent the successive addition of electrons to the datomic orbitals of the atoms. In this way, the transition metals represent the transition between group 2 elementsand group 13 elements.

What is the number of valence electrons for the elements in group 1?
The elements in Group 1 have one valence electron in their outermost s orbital.
How can the number of core electrons be determine from the periodic table?
By finding the atomic number minus the group number
What can be said about the electron configurations of all the elements in a group?
The electron configurations of all the elements in a group have the same number of valence electrons. Valence electrons are the electrons found in the outermost shell of an element.
How can you use a periodic table to predict the number of valence electrons an element has without having to draw the Bohr diagram?
In general, except for the transition elements, the group number will tell you the number of valence electrons. For example, Na is in group 1 and has 1 valence electron. Cl is in group 7 and has 7 valence electrons.
Elements in the same period have similar properties?
Elements of the same period have the same number of electron shells; with each group across a period, the elements have one more proton and electron and become less metallic. Hope this helped you with your homework. :P
Why elements are called transition?
Transition elements are called transition elements because the electrons in these elements are not in process of filling valence(outermost ) shell instead they are, in case of d-block elements, in process of filling penultimate shell. and in case of f- block elements, electrons are in process of filling next to the penultimate shell.
Why element 15 is put in 15th group . Why not in 5th group when its valency shell contains 5?
Elements whose atoms contain d orbital electrons are treated differently from other elements in a modern periodic table, largely because when the differentiating electron between two elements differing by a single atomic number is a d orbital electron, this differentiating electron generally goes into an atomic shell with a lower number than the outermost electron shell of the atom. The chemical behavior of elements with d orbital electrons, but not enough of them to fill the shell with the next lower electron shell number than that of the valence s and p orbital electrons in the outermost electron shell, is more difficult to predict than for other elements, because such d orbital electrons sometimes act as valence electrons but sometimes do not. In order to increase the ability of placement of elements in a periodic table to predict the number of valence electrons, it has become customary to use an "extended form" table, in which columns 3 through 12 are reserved for elements that contain at least one d orbital electron in a shell with a lower shell number than the s and/or p orbital electrons in the same atom, but do not contain a full shell of such d orbital electrons. The elements in these columns are called "transition elements". This arrangement of the periodic table leads to the convenient characteristic that the number of valence electrons in a non-transition element is the same as the column number of the element in the periodic table if that column number is less than 4 and is the last digit only of the column number if that number is 13 or more. This method of calculating the number of valence electrons in a non-transition element works also for the first three periods (rows) of the table, which do not contain any transition elements.
What elements have the same number of electron?
All elements in the same group have the same number of valence electrons.
What is the number of valence electrons for the elements in group 1?
The elements in Group 1 have one valence electron in their outermost s orbital.
What is the difference between the representative elements and the transition elements?
The elements in group 1 and 2 are the representative elements. Groups 3 through 12 are the transition elements. Transition elements are all metals and are found less noticably than they do across a period of representative elements. representative elements are always found in nature combined with other elements, they are all metals except for hydrogen.
How is an elements period related to its its electron confuguation?
An elements period is determined by the number of electrons it has in its outer shell.
How can the number of core electrons be determine from the periodic table?
By finding the atomic number minus the group number
What is about all elements that can be found in the same group?
All elements in the groups (excluding transition metals) have the same number of electrons as the group number.
What can be said about the electron configurations of all the elements in a group?
The electron configurations of all the elements in a group have the same number of valence electrons. Valence electrons are the electrons found in the outermost shell of an element.
What gives the transition elements their stability compared to the s block elements?
The amount of valence electrons, also known as the number electrons in the outermost ring of the atom.
How can you use a periodic table to predict the number of valence electrons an element has without having to draw the Bohr diagram?
In general, except for the transition elements, the group number will tell you the number of valence electrons. For example, Na is in group 1 and has 1 valence electron. Cl is in group 7 and has 7 valence electrons.
