What happens to the pull on the electrons in the Periodic Table?

I guess by pull of electrons you mean electronegativity.
Electronegativity increases across a period and decreases down a group.

Explain why atomic radius generally decreases as you go left to right across a row on the periodic table?
As you move from left to right across the Periodic Table, the number of protons in the nucleus of each successive atom increases by one. Correspondingly, the number of electrons also increases by one. However, if the elements in question are on the same energy level, the added ''pull" of the protons serves to pull the orbiting electrons closer to the nucleus, thus causing the radius of the atom to become smalller as you move from left to right. As you move down the periodic table, atoms get larger. As you move down the table, you continue to add protons and electrons. However, you also add energy levels and, in so doing, the orbiting (and available) electrons get further from the nucleus and the pull of the protons. It is the distance between protons and available electrons that allows the radius of the atoms to get larger. It also explains why reactivity increases as you go down the table. The pull of protons on the available electrons of small atoms is much greater than the pull of protons on the available electrons of large atoms, so the large atoms release their electrons much more readily.
What makes the atomic radius change along a period in the periodic table?
More protons in the nucleus pull the electrons in, making the atomic radius smaller.
Does sodium have a smaller atomic radii than sulfur?
The atomic radius of Na is greater than that of Si because as you move to the right across the periodic table there are more electrons which cause more attraction between the protons and electrons which cause them to pull closer together.
What trend in ionization energy occurs going down on the periodic table and why?
when you go down a group you get more shells and in those shell are electrons the further away the electrons are from the protons and neutrons the less energy you need to pull of the electrons.
What is the trend in atomic radii when moving from top to bottom?
As a general rule, when moving left to right on the periodic table the atomic radius decreases due to increasing electromagnetic attraction of the nucleus to the electrons.
What trend does the ionization energy follow going across the periodic table?
The correct answer is: The ionization energy increases because there are more protons to pull on the electrons.
What trends does the first ionization energy follow going across the periodic table?
The correct answer is: The ionization energy increases because there are more protons to pull on the electrons.

Sodium and chlorine are in the same period on the periodic table explain the difference in their sizes?
Sodium is larger than chlorine because chlorine has more protons and outer level electrons which gives the positive nucleus a greater pull on the outer electrons.
Why does the size of d-block elements decrease gradually in the periodic table?
As increase in proton number, the attraction from nucleus towards electrons increased. This will pull the electrons stongly. So, the size/ atomic radius decreased across the d-block.
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.
What makes the atomic radius change along a period in the periodic table?
More protons in the nucleus pull the electrons in, making the atomic radius smaller.
Does sodium have a smaller atomic radii than sulfur?
The atomic radius of Na is greater than that of Si because as you move to the right across the periodic table there are more electrons which cause more attraction between the protons and electrons which cause them to pull closer together.
How do you rank configurations by atomic radius?
Nuclear radius increases as you go down and to the left on the periodic table due to effective nuclear charge. Bassicaly, it means that sheilding of electrons by larger atoms having more things in the way that blocks the ability of the nucleus to pull on the electrons, thus the electrons are able to be further from the nucleus and have a larger radius.

when you go down a group you get more shells and in those shell are electrons the further away the electrons are from the protons and neutrons the less energy you need to pull of the electrons.
What trend does the first ionization energy follow going down periodic table?
The first ionization energy decreases because the outermost electron is farther from the nucleus. Apex
What happens to IE when moving down on the periodic table?
The general trend with Ionization energy as you move down a column on the periodic table is that IE decreases. Ionization energy is the amount of energy required to remove an electron from an atom. As you move down a column, the electron moves farther away from the nucleus and the electron shielding effect increases. There is less of a pull keeping the electron in thus making it easier to remove.
