Atomic Radius:Across
Decreases as you go across, because the pull from the protons pulls in the electrons closer making it smaller
Atomic Radius:Down
Increases, because you add more electron orbits so it is obviously getting bigger.
Ionization Energy:Define
The Energy required to remove an electron from an atom
Ionization Energy:Across
Increases as you go across, because obviously it’s harder to take away for example 10 electrons than just remove 1.
Ionization Energy:Down
Decreases, because it’s farther away from the nucleus anyways so it’s easier.
Tendancy and ability of an atom to attract other electrons to share.
Flourine is the most electronegative element so think of it as everything going to that one. It would increase as going across and then increase going up to flourine.
Covalent bond
the attraction that forms between atoms when they share electrons
Ionic bond
the force of attraction between opposite charges of ions
Polar Covalent Bond
a covalent bond where the united atoms have an unequal attraction for the shared electrons
Nonpolar Covalent Bond
a covalent bond in which the bonding electrons are shared equally by bonded atoms with a resulting balanced distribution of charges
