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.
What must happen for fluorine t become stable?
Fluorine becomes stable when it gains one electron to achieve a full outer shell of electrons, containing 8 electrons in total. This allows fluorine to attain a stable electron configuration similar to that of a noble gas.
If potassium has one electron in its outer shell what type of elements would it prefer to combine with?
Potassium would prefer to combine with elements that have seven electrons in their outer shell, such as chlorine, to achieve a stable octet configuration through ionic bonding. This completion of the outer shell helps both elements achieve a more stable electron configuration.
How many electrons must tantalum need to gain or lose to become stable?
Tantalum needs to lose 2 electrons to become stable. Tantalum has 73 protons, so losing 2 electrons will give it a full outer shell of 71 electrons, which is the most stable configuration for the element.
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.
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.
What must happen for sodium to become stable?
For sodium to become stable, it must lose one electron to achieve a full outer electron shell. This typically occurs through the formation of an ionic bond with another atom that can accept this extra electron, such as chlorine. Once sodium loses its electron and forms a stable bond, it becomes a stable compound.
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 beryllium loose to become stable?
Beryllium is a stable element.
What must happen for fluorine t become stable?
Fluorine becomes stable when it gains one electron to achieve a full outer shell of electrons, containing 8 electrons in total. This allows fluorine to attain a stable electron configuration similar to that of a noble gas.
How does potassium and fluorine atoms change their electron configuration to obain a noble gas structure?
Potassium can lose one electron from its outer shell to achieve a stable electron configuration similar to argon. Fluorine can gain one electron to fill its outer shell and attain a stable electron configuration like neon. In both cases, the atoms are trying to achieve a full valence shell and become stable like the nearest noble gas.
What must happen to a rock for it to become a metamorphic rock?
It must melt.
How many times must oxygen bond to become stable?
Oxygen must bond twice to become stable. In its stable form, oxygen molecules have a double bond (O=O), with each oxygen atom sharing two electrons.
What must happen before a hypothesis become a theory?
The Hypothesis Must Be Supported In Order For It To Become A Theory
When comparing the electron configurations of neon and fluorine what must happen for fluorine to become stable?
For fluorine to become stable, it needs to gain one electron to attain a full valence shell, similar to the electron configuration of neon. Fluorine has seven valence electrons in its outer shell, so gaining one electron would fill its outer shell and make it stable with a full octet like neon.
What must happen to a atom for it to become an ion with a positive plus 1charge?
It must loose an electron.
