Why does the change for the atomic radii of the elements for period 3 from sodium to argon look similar to period 2?

Because the trend is the same. Atomic radius decreases from left to right across a period.

What is the change in atomic radii for the elements in period 2?
Seventeen
What characteristics must two elements share if they are in the same period?
The same number of electron shells,thus similar atomic structure.
Does A Period Table Contain Elements That Have Similar Properties?
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
What do elements in same atomic period have?
Elements in the same period of the periodic table have sequentially increasing numbers of protons.
What is the atomic numbers of the elements in period 2?
Two. Period 1 contains H and He.

Does a period contain elements that are similar?
no. A period is a row of elements in the periodic table whose properties change gradually and predictably.

The same number of electron shells,thus similar atomic structure.

How are period and group trends in atomic radii are related to electron configuration?
The atomic radius decreases along the elements across a period. Along a group, there is an increment in the atomic radius of corresponding elements.
What do elements in same atomic period have?
Elements in the same period of the periodic table have sequentially increasing numbers of protons.
How are the elements in a period different?
By their atomic weight..protons and electrons.
What is the atomic numbers of the elements in period 2?
Two. Period 1 contains H and He.
Which group of the main group elements contains the largest elements - Atomic Radius?
Group-1 has largest atomic radius. It decreases across a period
Why are the elements in period three together?
They are placed in order of the atomic number.
What characteristics is shared by elements in the same period?
Elements in the same period have the same number of electron shells, moving across a period (progressing group to group), elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.
