it tells you the amount of electrons the atom has orbitting the atom and the nucleus
Electronegativity
it shows how many protons are present in an atom
forever
Because there wasnt a way to see an atom until recently and it was by thesis that tha atom was there.

The number of protons within an atom's nucleus can be determined by the atomic number as long as the atom is in its neutral state. Thus, 17 protons would be element 17 which is Cl.

The process known as polymerisation does.
It takes approximately 1 nanosecond for light to pass through a hydrogen atom.
lol idont want to tell u
The half-life of an atom is how long it takes for half of the atom's mass to radioactively decay. This occurs exponentially; therefore, after 2 of the atom's half-lives have passed, 3/4 of the atom will have decay (half during the first half-life, then half of the remaining mass, or one quarter, during the second).
Because they way it works it they smash plutonium ( which is radioactive) to split an atom. This produces radiation which is harmful and can last a long time.
