atom?

atom方面

以我雞水咁多既知識,electron都係obey圓形既軌道

咁果要甩電子做ion

所需既energy

係 KE=work done agaist proton's attractive force?

定係KEmin >/  mv^2/r:smile_41::smile_41:

The minimum energy required for electron to be removed from the atom is called the ionization energy.
You should notice that KE is not dimensionally equal to centripetal force as metioned, since KE has a unit of J and centripetal force has a unit of N. You should not compare them by saying KEmin>=mv^2/r.

sorry 我未學s orbital果D~~~
