1. In a period is a trend of decrease from left to right but it is not absolute.
2. In a group the atomic radius increase moving down.

O The periodic table of elements is the arrangement of elements according to?
The periodic table of elements is the arrangement of elements according to atomic number increasing from left to right across rows of the table.
How much does the atomic number increase bye as you go across a row on the periodic table?
Atomic number increases by one as we move from left to right in a periodic table.
What happens to the atomic number as you go from left to right across the periodic table and why does this happen?
Periods on the periodic table refer to the rows of elements. As the elements progress to the right, the atomic numbers increase, usually in steps of 1.
How did chemists organize the elements that were known?
Chemical elements are organized in the periodic table of Mendeleev.
What are the elements in the periodic table based on?
Atomic Number
WHAT BEST STATES THE TREND IN ATOMIC RADIUS ACROSS THE PERIODIC TABLE?
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
What happens to the atomic radius when you go from left to right on the periodic table of elements?
The atomic radius decrease, with several exceptions in periods 6 and 5.
Why does atomic size tend to decrease with increasing atomic number across a row of the periodic table?
electronegativity
O The periodic table of elements is the arrangement of elements according to?
The periodic table of elements is the arrangement of elements according to atomic number increasing from left to right across rows of the table.
How much does the number increase by as you go across a row on the periodic table?
The atomic number increases by 1 as one go across a row on periodic table. The elements are arranged in order of increasing atomic number.
How much does the atomic number increase bye as you go across a row on the periodic table?
Atomic number increases by one as we move from left to right in a periodic table.

Periods on the periodic table refer to the rows of elements. As the elements progress to the right, the atomic numbers increase, usually in steps of 1.
How did chemists organize the elements that were known?
Chemical elements are organized in the periodic table of Mendeleev.
What does the atomic number and atomic mass have to do with the arrangement of the elements on the periodic table?
The elements on the periodic table are arranged in order of increasing atomic number.
Do the elements to the right of the periodic table have small or large radii?
Across a period the atomic size decreases. Hence elements in the right side of the periodic table have small size / radii.
How are the size of the elements effected on the periodic table?
Atomic size increase down the group and decreases across the period.
How are the elements arranged?
atomic number
