What else can I help you with?
How can you tell whether or not an element will react with others element?
Depending on how many valence electrons in the element has, The other element could take away a valence electron to make eight
Does krypton have 8 valence electrons?
Yes, krypton has eight valence electrons.
How is an element's most likely oxidation state related to its valence electrons?
It indicates how many electrons are required to complete a full valence shell.
Which noble gas doesn't have 8 outer electrons?
Helium has only 2 valence electrons. The rest noble gases have eight.
What is the valence of selenium if has six valence electrons?
Two- Since it has six valence electrons, it can form two covalent bonds, making the valence two. If it is easier to think about it this way, eight valence electrons would stabilize the element. Eight minus six is two, giving us the same answer as before.
What is the symbol for one element that DOES NOT need eight electrons to have full set of valence electrons?
An element that does not require eight electrons for a full set of valence electrons is represented by the element symbol B. Boron only needs six electrons to complete its valence shell and achieve stability.
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.
What is a representative element with eight electrons in its valence shells is called?
Octet
What is the e-dot diagram for Ne?
Neon atoms have 8 valence electrons. Refer to the related link for an illustration of the electron dot diagram for neon.
How can you tell whether or not an element will react with others element?

How many valance electrons does helium have?
Helium has two valence electrons. It is the only noble gas not to have eight valence electrons. Helium has the electronic configuration 1s2.The Noble gases have eight valence electrons in their outer shell.
How can you tell whether or not an element will react other elements?
Depending on how many valence electrons in the element has, The other element could take away a valence electron to make eight
How can one draw a Lewis dot structure for an element?
To draw a Lewis dot structure for an element, first determine the total number of valence electrons for that element. Then, place the electrons around the element symbol in pairs, with no more than two electrons in each pair. Remember to follow the octet rule, which states that most elements strive to have eight electrons in their outer shell.
Does krypton have 8 valence electrons?
Yes, krypton has eight valence electrons.
How valence electrons does helium have?
Helium has two valence electrons. It is the only noble gas not to have eight valence electrons. Helium has the electronic configuration 1s2.The Noble gases have eight valence electrons in their outer shell.
How is an element's most likely oxidation state related to its valence electrons?
It indicates how many electrons are required to complete a full valence shell.
Number of valence electrons in xenon?
Xenon has 8 valence electrons.
