What else can I help you with?
How many valence electrons does the nobel gas group have?
Noble gases have a full valence shell with 8 electrons, except for helium which has 2. This makes them very stable and unreactive.
How many valence electrons will result in chemical stability for an atom?
A full outer shell of electrons typically results in chemical stability for an atom. This corresponds to 8 valence electrons for most atoms (except hydrogen and helium, which only need 2 valence electrons for stability).
A family of unreactive element whose atoms do not gain lose or share valence electrons?
Noble Gasses.
What are valence electrons and how do they relate to the noble gases?
Valence electrons are electrons in the outermost shell (or outermost energy level or outermost orbital) in an atom. Noble gases have 8 valence electrons. But helium (a noble gas) has only 2 valence electrons.
Explain why noble gases are unreactive in terms of electron shells?
Noble gases have a full outer electron shell, making them stable and unreactive. They do not easily gain or lose electrons since their electron configuration is already at its most stable state. This full outer shell configuration, known as the octet rule, makes noble gases chemically inert.
Is the element reactive or satble how do you know?
If the element has a full valence shell, such as the noble gases, then it is unreactive. It the element is missing few valence electrons of has few valence electrons, then the element is very reactive, such as the sodium.
What element has a stable 2 valence electrons?
The element with a stable 2 valence electrons is helium. Helium has a full outer electron shell with 2 electrons, making it very stable and unreactive.
How many valence electrons does the nobel gas group have?
Noble gases have a full valence shell with 8 electrons, except for helium which has 2. This makes them very stable and unreactive.
Which group has a complete set of valence electrons in their outermost energy level?
Noble gases have a complete set of valence electrons in their outermost energy level, which is why they are known to be stable and unreactive.
How many valence elactrons do all the elements in neon's family have?
8 valence electrons are there in in neon's family .They are stable in nature.
Why is chlorine very reactive and argon is unreactive?
Chlorine is very reactive because it has seven electrons in its outer shell, making it highly likely to gain one electron to achieve a stable electron configuration. Argon is unreactive because it already has a full outer shell of electrons, so it does not need to gain or lose any electrons to achieve stability.
Valence electrons of helium?
Helium has two valence electrons in the 1s orbital.
Valence electrons in neon family?
The neon family, or noble gases, has a full outer electron shell containing 8 electrons. This means that each noble gas in the neon family has 8 valence electrons, which makes them stable and unreactive.
How many valence electrons will result in chemical stability for an atom?
A full outer shell of electrons typically results in chemical stability for an atom. This corresponds to 8 valence electrons for most atoms (except hydrogen and helium, which only need 2 valence electrons for stability).
A family of unreactive element whose atoms do not gain lose or share valence electrons?
Noble Gasses.
Justify why the noble gas family is unreactive?
In short, an element's valence shell is full and most stable when it contains eight electrons (this stability is the reason that the noble gases are so unreactive).
Inert gas having 8 valence electrons?
mercury is an inert gas having 8 valence electrons
