Covalent bonds formed when two atoms share an electron, as opposed to an Ionic bond where one atom takes an electron(or two) from another atom.
In descriptive investigations, we still haven't formed any hypothesis yet so we seek information by asking question.
It's not repeatable because repeating the questions over and over again without any clue about what we want to seek is completely waste of time.
Hope this helps xox :)
A large unstable nucleus becomes tinier and emits an alpha
particle during Alpha decay. 4/2He or the alpha particle that consists of two
protons and two neutrons can be discharged from the nucleus during the disintegration
of radioactive decay. It has a charge of
positive 2.

It did not explain how the atoms electrons are arranged in the space around the nucleus it did not explain whole the negative charged electrons are not pulled into the positive nucleus.
