How does electronegativity increase or decrease in modern periodic table?
Electronegativity generally increases as you move from left to right across a period in the modern periodic table due to increasing nuclear charge and a stronger pull on electrons. Electronegativity decreases as you move down a group in the periodic table because atomic size increases and the outer electrons are farther from the nucleus, reducing the attraction for additional electrons.
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.
When looking across a period of the periodic table from left to right when happens to the atomic number and electronegativity?
As you move across a period from left to right in the periodic table, the atomic number of the elements increases by one with each element. Electronegativity also increases across a period from left to right due to the increasing nuclear charge and decreasing atomic radius, which results in stronger pull on electrons.
Does electronegativity increases from left to right across each row of the periodic table and also increases down each column?
Electronegativity generally increases from left to right across each row of the periodic table because atoms have more protons in the nucleus, increasing their ability to attract electrons. Electronegativity also tends to decrease as you move down each column because the distance between the nucleus and outer electrons increases, reducing the nucleus' pull on 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.
What happen to the atomic as you from the bottom to the top of the periodic table?
As you move from the bottom to the top of the periodic table, the atomic size decreases. This is because the number of protons in the nucleus increases, leading to a stronger pull on the electrons. Electrons are added to the same energy level while moving up the table, resulting in a smaller atomic radius.
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.
Do the elements to the right of the periodic table have small or large radii?
Elements to the right of the periodic table have smaller radii due to increased effective nuclear charge, which attracts the electrons closer to the nucleus. This results in a greater pull on the outer electrons and smaller atomic radii overall.
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.

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.
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.
When looking across a period of the periodic table from left to right when happens to the atomic number and electronegativity?
As you move across a period from left to right in the periodic table, the atomic number of the elements increases by one with each element. Electronegativity also increases across a period from left to right due to the increasing nuclear charge and decreasing atomic radius, which results in stronger pull on electrons.

Which element would be more likely to pull in electrons during the formation of a compound?
An element with a higher electronegativity value would be more likely to pull in electrons during the formation of a compound. Elements like fluorine, oxygen, and nitrogen, which are towards the upper right of the periodic table, tend to have high electronegativity values.
