What else can I help you with?
What quantity of an element in the periodic table never changes?
The atomic number
Who was or is Mendeleev in periodic tables?
He is the founder of the periodic table. He arranged the elements according to the atomic masses. Few changes are made in his periodic table to make the modern periodic table.
How does atomic number explain the arrangement of the periodic table?
According to the modern periodic table "Elements are the periodic function of their atomic number".They are arranged in increasing atomic no. in the periodic table.
When you move from left to right on the periodic table what are some of the major changes?
When you move from left to right on the periodic table, the atomic number of the elements increase.
What is the atomic number of permanganate on the periodic table?
The atomic number of permanganate on the periodic table is 25.
What is the atomic number of scandium on the periodic table?
The atomic number of scandium on the periodic table is 21.
What is the atomic number of uranium on the periodic table?
The atomic number of uranium on the periodic table is 92.
Why does the atomic mass on the periodic table progressively changes left to right and top to bottom why?
Because there are increasingly more protons, electrons, and neutrons. Atomic mass is the average number of neutrons in all of the isotopes(different types) of a specific element, meaning you can sometimes have decimal masses. But, the atomic number is never a decimal because the atomic number is just a numbering system for all the elements.
Is the periodic table organized by atomic numbers?
The Periodic Table is.
What has a 5.09 on the periodic table?
Platinum has a relative atomic weight of 195.09(you will not find 5.09 anywhere else on a periodic table.)
Changes in the Periodic Table over time?
The periodic table has evolved over time as new elements have been discovered and our understanding of atomic structure has improved. Elements have been reorganized based on their atomic number instead of atomic weight, and new elements have been added as they were synthesized in laboratories. The table has also been expanded to include more information about each element, such as atomic structure and properties.
Which pattern do atomic number in periodic table have?
Elements are arranged in the increasing order of their atomic number in the periodic table.
