In the Periodic Table, the atomic size increases with every period due to addition of an extra shell.
The atomic size decreases with every group since no. of electrons and protons are increased with every group across a period leading to extra electrostatic force
of attraction between electrons and the nucleus and thus shrinking the size of the atom.

Does Francium have the largest atomic radius on the periodic table?
Francium has the largest atomic radius in Group 1 of the Periodic Table.
How does the atomic raduis change across a period of the periodic table?
Atomic radius usually decreases from left to right across a period of the periodic table.
What element has a relative atomic mass of 15.5?
Relative atomic mass, also called atomic weight, is listed on the periodic table for each element. There is no element listed on the periodic table with a relative atomic mass of 15.5.
What is used to order elements on the periodic table?
the elements in the modern periodic table are arranged according to their increasing atomic number.
What is the difference in the modern periodic table and Mendeleev's table?
The periodic table is now complete and can be displayed using the integral atomic numbers. In Mendeleev's time there were still unknown elements. In fact, one of the primary uses of his table was to predict the properties of elements that had not yet been isolated. (His 1869 table included speculative names for some expected elements.) -- In Mendeleev's periodic table, transition elements were placed in another group. --In Mendeleev's periodic table, noble gases were written on left side. In the modern periodic table, noble gases are written on right side.
Which pattern do atomic number in periodic table have?
Elements are arranged in the increasing order of their atomic number in the 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.
What pattern repeats across the rows on the periodic table?
they go by there atomic mass's
What is the modern periodic table is now arranged according to?
Now modern periodic table is arranged in order of increasing atomic number. The properties are found to be periodic when arranged in this pattern.
How are the elements arranged?
atomic number
How is the atomic number used to crate a periodic table?
The elements are arranged in order of increasing atomic number.The properties are found to be periodic when arranged in this pattern.
What occurs as you move from the left to the right on the periodic table?
Many properties change as you move from left to right on the periodic table. For example: atomic number increases; electronegativity increases; atomic radii decrease etc. etc.
What scientist determined that atomic mass did not determine the pattern of the periodic table?
Henry Moseley
How was mendeleev's periodic table alike the periodic table now?
Mendeleev's periodic table was arranged in order of increasing atomic mass.Modern periodic table is arranged in order of increasing atomic number.
Who recognized a pattern in the properties of the elements and made the first periodic table?
In 1869, a Russian scientist named Dmitri Mendeleev arranged the elements in a table according to their atomic mass, this was the first periodic table. However, a few elements didn't fit the pattern in Mendeleev's table, so a new table had to be made, and that table is today's periodic table which is arranged by atomic number, and not atomic mass.
Is the periodic table organized by atomic numbers?
The Periodic Table is.
Elements are organized in the periodic table by their?
The periodic table is a function of the atomic number.
