the distance from the center of the nucleus to the outermost energy level

• atomic radius

• coulomb force

• electronegativity

• ionization energy

the amount of energy needed to remove one valence electrons from an atom

• ionization energy

• coulomb force

• electronegativity

• atomic radius

a measure of how strongly an atom attracts a pair of electrons to itself when bonded with another atom

• electronegativity

• ionization energy

• atomic radius

• ionic radius

positive ion

• cation

• anion

negative ion

• anion

• cation

atomic radius pattern left to right ---->

• decrease

• increase

why does atomic radius decrease left to right

• more protons left to right, increasing the FOA, condensing the atom

• more protons left to right, increasing the FOA, decreasing the energy needed to remove an electron

• more protons left to right, increasing the FOA, increasing the energy needed to remove an electron

• more protons left to right, increasing the FOA, expanding the atom

why does atomic radius increase top to bottom

• the number of rings increase, so FOA weakens, and the atom expands

• the number of rings increase, so FOA weakens, and the atom condenses

• the FOA weakens top to bottom due to the increasing atomic radius top to bottom.This means the valence electron are further away from the nucleus, requiring less energy or remove an electron.

• the FOA increases top to bottom due to the increasing atomic radius top to bottom.This means the valence electron are further away from the nucleus, requiring more energy to remove an electron.

what is the pattern that ionization energy follows left to right?

• increase

• decrease
