When a bond is created how many valence electrons are needed to fill an octet?
It depends on what element you start with.
How many valence electrons does a bromine anion contain?
Eight valence electrons.
What elements have less than eight valence electrons?
Any element except the elements in group 8, 9, 10, 11, 12 and 18 have lesser than 8 valence electrons.
How many valence electrons of an atom does xenon have?
26
How many electrons does Ba has?
Valence electrons are electrons that are on the outside "shell." In Group (column) 1, there is only one valence electrons for each element. In Group (column) 2, there are two valence electrons. Group 13: 3 valence electrons Group 14: 4 valence electrons Group 15: 5 valence electrons Group 16: 6 valence electrons Group 17: 7 valence electrons Group 18: 8 valence electrons There is no Group 19, so this list is done. For the metals, each element will need to be mapped out utilizing the Bohr Diagram design or something of the like as valence electrons are difficult to define due to the grouping on the periodic table. The most valence electrons that can be in an outer shell is eight. Barium (Ba) is in Group (column) 2, and thus has only two valence electrons.
What is a representative element with eight electrons in its valence shells is called?
Octet
How does an atom of a representative element achieve its most stable state?
The valence shell must be completed to eight electrons.
What is the the symbol for one element that DOES NOT need eight electrons to have full set of valence electrons?
He
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.
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.
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.
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.
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
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?
