Which of the following has a higher electronegativity/
Calcium, Arsenic, Vanadium, Bromine
Bromine
Which of the following has the highest ionization energy?
Argon, Helium, Neon
Helium
Which ions are bigger - - cations and anions?
Anions are bigger because they gain electrons
Why are the outermost electrons of an atom easier to remove?
The electrons are farther away from the nucleus and don’t feel the pull of the nucleus
Explain why the atomic trend for atomic radii “decreases as you go left to right across a period?”
The pull of the nucleus gets more and more positive as you go across a period, pulls the electrons closer
What is the difference between electronegativity and ionization energy?
Electronegativity is the ability of atoms to attract electrons to themselves - - ionization energy is the energy required to remove one electron from an atom’s shell
How are ions created?
Cations are created by losing an electron and so it loses a negative charge and becomes postitive
Anions are created by gaining an electron so it gain a negative charge and becomes negative
