How many valence electrons do alkaline earth metals have?
The alkali earth elements have TWO valence electrons.
A representative element with eight electrons in its valence shell is said to be at .?
A representative element with eight electrons in its valence shell is said to be at a stable electron configuration, known as the octet rule. This means the element has achieved a full outer shell of electrons, making it less likely to react with other elements to gain stability. Examples of such elements are noble gases like neon and argon.
What element has an atomic number lower than that of aluminum less valence electron than the the group 16 elements?
Nitrogen
How can you tell from an element's number of valence elns whether the element is more likely to form a caor an anion?
If an element has less than four valence electrons, it will tend to lose its valence electrons and form cations. If an element has more than four valence electrons, it will tend to gain electrons and form anions. An element that has four valence electrons will tend to form covalent bonds rather than ionic bonds.
What kind of elements has less than 4 valence electrons?
Boron group, transition metals, alkaline earth metals and alkali metals are listed in the Periodic Table are having less than four valence electrons
Which elements is less reactive an element whose atoms have seven valence electrons or an element whose atoms have eight valence electrons?
the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.
Is the stability of the noble gas elements other than helium is a result of their having eight valence electrons?
Yes, the stability of noble gas elements other than helium is due to their having eight valence electrons. This electron configuration, known as an octet, gives them a full outer energy level, making them highly stable and less likely to form chemical bonds with other elements.
What are the only elements that have eight electrons in their outer orbitals?
The elements that have eight electrons in their outer orbitals are the noble gases, specifically helium, neon, argon, krypton, xenon, and radon. These elements have a full valence shell, giving them stability and making them less likely to form chemical bonds.
Why is an atom that has eight valence electrons less reactive?
Because it is already stable!
Is the most atom more or less stable when they have eight valence electrons true or false?
less stable

What is the relationship between the number of valence electrons and the conductivity of the given elements?
Less valence electrons (1 to 3) in the outermost shell of an atom usually means a good conductor. (silver, cooper, gold). 5 t0 8 valence electrons are found in glass, rubber, ceramic, plastic, non-conductors.
What kind of elements has less than 4 valence electrons?
Boron group, transition metals, alkaline earth metals and alkali metals are listed in the Periodic Table are having less than four valence electrons
What contains eight elements?
Element 1 is hydrogen; element 8 is oxygen. Thus water, H2O, is such a substance. Another less familiar one is hydrogen peroxide, H2O2.
