What is a partially filled outer electron level makes with?
A completley filled out electron level makes the atom stable
Process when an Atom change from stable to unstable?
Nuclear reactions
What will an atom of iodine most likely do to be stable?
Steal an electron from an atom of a different element.
Can a radioactive element completely decay so that it is all stable matter?
A radioactive element (atom) can decay up to a stable isotope.
What is the term for the element that a radioactive isotope decay into?
The atom that results from nuclear decay is called the daughter atom. The element of the daughter atom would be called the daughter element. The atom that decayed is called the parent.
How Difference atom and element?
atom and elements are different because one atom makes an element and a element is a pure substance and a atom is a basic particle
How many valence electron are needed for an atom to be stable?
It depends on the atom. List what element the atom is from.
What is the process where in a nuclear reactions of atom are being transformed into atoms of simple element?
nuclear fission
What do you mean by bombarding element?
A nuclear reaction in which an atom is bombarded with elementary particles or with a lighter atom.
Is the krypton element stable or unstable?
no it is not stable bcoz if an atom needs to be stable it needs to have 8 electrons in the valency (outermost) shell,where as a krypton has only 2 in its valency electron.
What did radioactivity reveal about the atom?
That some atoms are not stable, and that they release mass from their nuclei to become other isotopes or elements. Until the process of fusion was understood, nuclear decay was the only known way for one element to become another element.
An amtom undergoes a reaction ant attains a more stable from how do you know is it was chemical or nuclear reaction?
If an atom undergoes a reaction and attains a more stable form, you know if the reaction was a chemical reaction or a nuclear reaction by studying what exactly happened to the atom.
