What is the longest period in the periodic table?

Who pot gold on the periodic table of elements?
Gold has the atomic number 79; group 11, period 6.
Why is the atomic number included in the periodic table?
Presumably because atomic number is the fundamental characteristic for organizing the periodic table itself. Every element in the interior of a period of the periodic table has an atomic number greater by 1 than its neighbor to the left and less by 1 than its neighbor to the right; every element (except hydrogen) at the left end of a periodic table period has an atomic number greater by one than the rightmost member of the preceding period; and every element at the right end of a periodic table periodic has an atomic number less by 1 than the leftmost element in the succeeding period, if such a succeeding period exists.
Why is roentgenium on the periodic table of elements?
Roentgenium is a transactinoid chemical element. It is placed in period 7, group 11 of the periodic table. The atomic number is 111.
Write a sentence that describes the purpose of the periodic table?
The elements of the periodic table are arranged in groups and periods. All of the elements in a period have the same number of atomic orbitals where as in a group all the elements have the same number of valence electrons.
How is the periodic law organized?
The period law states that the elements are the periodic function of their atomic number. Hence they are arranged in order of increasing atomic number.
How are the elements arranged?
Elements are arranged on the periodic table based on their atomic number, which is the number of protons in their nucleus. This arrangement groups elements with similar properties in columns called groups or families, while elements in the same period have the same number of electron shells.
Are elements in a period arranged alphabetically?
NO!!! Elements in a Period are arranged by Atomic No. / Proton No. If we take PERIOD 1. . the two elements are Hydrogen and Helium, in that order. H**ydrogen , Hel**ium are NOT in alphabetical order.
What is the longest period in the periodic table?
6th and 7th period are the longest period of the perodic table
What are characteristics of the period table?
The elements in the periodic table are arranged in order of increasing atomic number.
Which position in the periodic table contains the element with the highest atomic number?
In a given period, group 18 elements will have the highest atomic number.
What does the period number on a periodic table represent?
the Atomic number on Periodic Table is the identity of an element in the table , it gives the indications about Group, period and Block of elements it also predicts the chemical and physical properties of the element.
What is the atomic number of Periodic Table element Period?
The atomic number of the Periodic Table element Period is 92.
What are four things on the periodic table that tells you about the elements atoms?
the atomic number, the atomic weight, the atomic symbol and atomic name.
Where is platinum on the periodic table of elements?
Platinum is located in Group 10 and Period 6 of the periodic table of elements. It has the atomic number 78 and the symbol Pt.
How are period arranged on the periodic table?
The elements are arranged in order of increasing atomic number in the Periodic Table. The rows are called periods and the columns are called groups.
Where is the transuranium elements located on the periodic table?
Transuranium elements are elements that appear after uranium. Elements with atomic number 93 to 103, appear in the actinides whereas elements with atomic number 104 to 118 appear in the 7th period.
