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
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.
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.
Does krypton have 8 valence electrons?
Yes, krypton has eight valence electrons.
Which noble gas doesn't have 8 outer electrons?
Helium has only 2 valence electrons. The rest noble gases have eight.
What is the symbol for one element that DOES NOT need eight electrons to have full set of valence electrons?
The element is helium, with symbol He.
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

When a bond is created how many valence electrons are needed to fill an octet?
It depends on what element you start with.
Does krypton have 8 valence electrons?
Yes, krypton has eight valence electrons.
How valence electrons does helium have?
