Is potassium 40 a stable isotope?
no
What do radioactive elements gain when they emit radiation?
They become slightly more stable with each decay until they become stable and stop decaying.
Atoms join with each other to become more like this?
stable
Did the absence of the catalyst and effect on the outcome of the thermal decomposition of potassium chloride?
Potassium chloride is stable to thermal degradation.
What is the stable isotope called?
Each isotope, stable or unstable, has a specific symbol; for example K-40 for potassium 40.
What must happen for potassium to become stable?
Lose one electron
How many electrons does potassium need to gain or loose to become more stable?
Potassium (K), an Alkali Metal in Group 1 with atomic number 19, has a single valence electron in its outermost shell. Therefore it only needs to lose one electron in order for the element to become stable.
When atoms combine to form compound do they become more stable or less stable?
More stable
How can nitrogen become more chemically stable?
Nitrogen is sufficiently stable.
In order to fill their outer most shells and become more stable atoms form what?
In order to fill their outer most shells and become more stable atoms form BONDS.
To become more stable fluorine is likely to?
To become more stable, fluorine is most likely to gain 1 electron and form F- ion.
Is potassium 40 a stable isotope?
no
Does oxygen atoms become more stable or less stable when oxygen forms compounds?
Oxygen becomes more stable when it forms compounds.
What is more unstable magnesium fluoride potassium iodide or hydrogen peroxide?
Hydrogen peroxide is the least stable.
Which of the following metals is the least stable Silver Potassium Iron or Aluminum?
Potassium.
Why does potassium atom become positively charged and fluorine becomes negatively charged?
Potassium only needs to lose on electron (gain a positive charge) to have the same electron structure as Argon and thus very stable. Similarly, fluorine only needs to gain one electron (become negatively charged) to gain the very stable Neon structure.
Is potassium iodine an ionic or covalent bond?
Yes! K's atomic number is 19 and wants to become more stable if it was 18 so it wants to give up an electron so it is K+. CL's atomic number is 17 and would become more stable if it were 18 so it wants to gain an electron so it can be CL-. K and CL are now ions hence Ionic Bond.
