the atomic radii decreases as you move from left to right on the Periodic Table, because in the same row, any added electrons are in the same orbital level. because of this, as you add protons to go from left to right, you have more protons per electron per degree of electron shielding (caused by other orbital levels of electrons). as such, the electrons are more strongly attracted to the protons, and thus their orbits around the atom's protons become smaller.
What else can I help you with?
What happens to radii of the elements between two highest peaks?
The radii of elements increase across a period up to the peak, then decrease after the peak. This trend occurs due to the change in electron configuration and effective nuclear charge as you move from left to right within a period.
Which characteristics both generally decrease in period three from left to right?
Atomic radii decreases from left to right in the periodic table
How does atomic radii increase or decrease in the table?
Atomic radii generally increase from top to bottom within a group (with more electron shells) and decrease from left to right across a period (due to increasing nuclear charge). This trend is influenced by the balance between the increasing positive nuclear charge and the increasing number of electron shells, which can shield the outer electrons from the nucleus.
Are the atomic radii of Mn and Fe same?
No, the atomic radii of Mn (manganese) and Fe (iron) are not the same. Typically, atomic radii decrease across a period (from left to right on the periodic table), so Fe would have a smaller atomic radius compared to Mn.
How do the radii of metals in each period compare with the radii of nonmetals in that period?
In each period of the periodic table, the atomic radii of metals are generally larger than those of nonmetals. This is due to the fact that metals tend to have fewer valence electrons and a weaker effective nuclear charge, allowing their outer electrons to be located further from the nucleus. In contrast, nonmetals have higher electronegativity and stronger nuclear attraction, resulting in smaller atomic radii. As you move from left to right across a period, the atomic radii of both metals and nonmetals decrease, but the difference in size between the two categories remains consistent.
Why does the atomic radii decrease across a period?
The atomic radii decrease across a period because as you move from left to right, the number of protons and electrons in the atoms increases, leading to a stronger attraction between the nucleus and the outer electrons. This results in the electrons being pulled closer to the nucleus, making the atomic radius smaller.
As you go from left to right across a period the atomic radii does what?
Increases
Why does the change for the atomic radii of elements in period 3 from sodium to argon look similar to period 2?
The atomic radii of elements in period 3 from sodium to argon decrease due to a greater nuclear charge pulling electrons closer to the nucleus. This trend is similar to period 2 because both periods follow the same pattern of increasing nuclear charge as you move across the period, leading to a similar decrease in atomic radii.
What happens to the radii of the elements between 2 highest peaks?
The radii of elements generally decrease as you move from left to right across a period in the periodic table. The radii then increase as you move down a group in the periodic table. This trend is due to changes in the atomic structure of the elements.
What happens to radii of the elements between two highest peaks?
The radii of elements increase across a period up to the peak, then decrease after the peak. This trend occurs due to the change in electron configuration and effective nuclear charge as you move from left to right within a period.

What trend in atomic radii do periods 3 through 6 have in common in the periodic table?
Atomic radii generally decrease across periods 3 through 6 in the periodic table. This is because as you move from left to right across a period, the number of protons and electrons increases, leading to stronger attraction between the nucleus and the electrons, pulling the outer electrons closer to the nucleus, thus decreasing the atomic radius.
Graph the atomic radii for the first 20 elements?
I'm unable to graph atomic radii in this text-based format. However, you can find data on atomic radii for the first 20 elements in a periodic table resource or chemistry textbook. Atomic radii generally decrease across a period from left to right and increase down a group from top to bottom.

Does atomic radius have a bigger atomic number as you go to the right of the periodic table?
Yes. Generally atomic radii turn to decrease as you move across the periodic table from left to right. this is because the nuclear charge increases as you move right across the period but the electron screening remains the same. consequently, the protons in the nucleus has a greater pull on the electrons.
