What else can I help you with?
How can you use the word stable to explain why the alkali metals tend to lose valence electrons?
The alkali metals tend to lose valence electrons because they have one electron in their outermost energy level, which makes them unstable. By losing this electron and achieving a full outer shell, they become more stable like the noble gases. This stability is the driving force behind their tendency to lose valence electrons.
Is each ion stable?
No, not all ions are stable. Ions can be stable or unstable depending on their electron configuration. Stable ions often have a full valence shell, while unstable ions may have an incomplete valence shell, leading to reactivity in order to achieve stability through gaining or losing electrons.
Is sodium's outer shell stable?
No, sodium's outer shell is not stable because it only has one electron in its outer shell. Sodium will readily react with other elements to achieve a stable electron configuration by losing this electron.
What of the element out of calcium argon sodium nitrogen oxygen and chlorine can become stable by losing 1 electron?
Sodium. A sodium atom has one valence electron in its 3rd energy level. This is very unstable, so a sodium atom will lose that single valence electron to another atom (nonmetal), and the 2nd energy level will then have 8 valence electrons, which is stable. The positively charged sodium ion, Na+, will bond with a negatively charged ion; either a nonmetal or a polyatomic ion.
What is the difference between a stable and unstable electronic configuration?
Stable electronic configuration is when the valence shell of an element is completely filled (8 electrons) whereas unstable electronic configuration is when the valence shell of an element is not completely filled
What is the valence electrons in hydrogen?
there is one valence electron in hydrogen, and it needs one more electron to become stable
Which of these can become stable by losing 1 electron calcium argon sodium nitrogen oxygen chlorine?
Sodium can become stable by losing 1 electron, forming a sodium ion with a 1+ charge, with the formula Na+. By losing its single valence electron, the resulting sodium ion achieves the noble gas configuration of neon, so that it has an octet (8) of valence electrons.
What iodine makes?
Iodine is reactive because it has 7 valence electrons and is unstable. It needs one more electron to get 8, which would give it a noble gas configuration, and which would make the iodine atom stable. Iodine reacts with other elements in order to gain the needed electron and therefore become stable.
All atoms become stable when they have how many valence electrons?
Atoms become stable when they have a full outer electron shell, which typically means having 8 valence electrons (except for hydrogen and helium, which are stable with 2 valence electrons). This stable configuration is known as the octet rule.
Can calcium become stable by losing 1 electron?
Calcium loses its two valence electrons to become Ca 2+ ion.
How will sodium and chlorine become stable?
Sodiumbeing in group 1 needs to loose 1e- to become stable. Chlorine being from group 17 needs to gain 1e- to become stable. Sodium gives its extra electronto the chlorine atom. Now both have 8 electrons in their valence and are stable. The sodium gets a positive charge because it lost and electron. The chlorine gets a negative charge because it gained an electron.This creates an ionic bond
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.
