The name of elements 57-71 are the inner transitons?
The elements in a given period have the same number of core electrons.
On the Periodic table, horizontal rows are given the technical term "periods", while vertical columns are called "groups". Elements in the same period are similar in that they have the same number of energy levels.
In a given period, group 18 elements will have the highest atomic number.
As we go down the periodic table the number of electron shells goes on increasing by 1 and the periods are numbered according to the number of shells present in the atom of elements in that period. The maximum number of electrons in a shell is given by the formula, e=2n2 (where, e-maximum no. of electrons; n-the nth shell counted from the nucleus). So, the 1st shell has maximum 2, the 2nd 8, 3rd 18 and so on. Every period starts with a new shell and as we go across the periods from left to right one by one electron goes on adding to the same shell. Thus the maximum no. of electrons for a shell is present in the last atom of that period and no. of elements in a period is equal to the maximum no. of electrons for that period. So, the number of elements in successive periods goes like 2, 8, 18, 32 and so on.
The Periodic table is a representation of all elements grouped in a manner that lists elements with similar properties in columns. Adjacent columns have deceasing or increasing characteristics
Elements are arranged in order of their Proton Number/Electron Number. they are NOT arranged in Atomic Mass , because a given element my have isotopes, which alters the Atomic Mass.

A birth rate is a number of births that occur in a period of time in a given area.
The answer depends on the spinner: how many sides it has and how they are numbered. These details are not given in the question and so there is no way to answer the question.The answer depends on the spinner: how many sides it has and how they are numbered.
