Unit 3 review

as atoms absorb and release energy, electrons

• will spin in place

• will move throughout the atom to different energy levels

• will turn into different elements

• will lose/gain neutrons

As you go down the periodic table (top to bottom)

• the size, ionization energy, and electronegativity all increase

• size increases, while electronegativity and ionization energy both decrease

• size decreases, while electronegativity and ionization energy both increase

• size and electronegativity increase, ionization energy decreases

Electronegativity is...

• the ability of an atom to attract/ accept electrons
• the ability of an atom to lose electrons
• the energy required to remove an electron from a specific atom
• how easy it is to make friends.
