Which of the following metals is least stable of potassium silver iron and aluminium?
Answer is potassium. You have seen silver,iron and aluminium. You must not have handled potassium.
How many electrons does a stable atom of potassium have?
Potassium's atomic number is 19. Thus, it has 19 positively charged protons. To make it neutral, it must also have 19 negatively charged electrons.
How many electrons must tantalum need to gain or lose to become stable?
It needs to lose 3.
How many electrons would be required to make an oxygen atom stable?
It must gain 2 electrons to become stable then it would have a charge of -2 and be iso-electronic with Neon.
Why do atoms tend to be bonded to other atoms?
The correct answer is: Atoms are often more stable when bonded to other atoms
What must happen for sodium to become stable?
sodium must lose one electron
What must happen for a noble gas such as krypton to become stable?
Nothing. Krypton is already just about as stable as it's possible for an element to get.
When comparing the electron configurations of neon and fluorine what must happen for fluorine to become stable?
flourine must gain one electron
Which of the following metals is least stable of potassium silver iron and aluminium?
Answer is potassium. You have seen silver,iron and aluminium. You must not have handled potassium.
How many electrons must beryllium loose to become stable?
Beryllium is a stable element.
How many electrons does a stable atom of potassium have?

What must happen before a hypothesis become a theory?
The Hypothesis Must Be Supported In Order For It To Become A Theory
How many times must oxygen bond to become stable?
it needs to bond twice
What must happen for a nucleus to be stable?
The strong nuclear force must balance electrostatic forces in the nucleus
What does an atom have to do to become stable?
Physically - If radioactive the nucleus must go through 1 or more decay steps until it becomes a stable isotope.Chemically - Become unionized and have all electrons relax to ground state.
How many electrons must tantalum need to gain or lose to become stable?
It needs to lose 3.
