Phosphorus will electrons to complete its octet changing it into a(n) .?
Phosphorus need 3 electrons to complete its octet.
Why are the halogens so reactive and noble gases not reactive?
Because noble gases don't need to give or take any electrons - they have a perfect octet configuration. Where as halogens need to gain or lose electrons and will easily react to other halogens that need to lose or gain.
How many electrons does neutral selenium atom need to fill outermost shell?
Selenium needs two more electrons.
What is group 18 in the periodic table called and why?
These are the "noble gases." They are chemically inert, because they have a full octet of electrons in their valence energy level. Therefore, they do not need to lose or gain electrons to achieve stability; rather, they are naturally stable, which is why they do not react.
According to the octet rule what is the ideal number of electrons in the valence shell?
The word "octet" is a clue. 8- this means it is full and does not need to react.
How many electrons does selenium need to lose or gain to be stable?
gain 3
Can a Neutral unbonded atom complete valence octet?
if it is a noble gas it already has an octet, otherwise, it would need to gain or use electrons to complete an octet and would no longer be neutral or unbounded.
What does atoms have to do to fill the outermost energy level?
they need to either gain or lose electrons to create an octet. It depends on the atom. an octet is when an atom has a full outermost energy level
Phosphorus will electrons to complete its octet changing it into a(n) .?
Phosphorus need 3 electrons to complete its octet.
Why are the halogens so reactive and noble gases not reactive?
Because noble gases don't need to give or take any electrons - they have a perfect octet configuration. Where as halogens need to gain or lose electrons and will easily react to other halogens that need to lose or gain.
How many electrons do all halogen family elements need to gain in order to attain a noble gas configuration?
They need 7 more to complete the octet.
How many electrons does neutral selenium atom need to fill outermost shell?
Selenium needs two more electrons.
How many does the atoms electrons in their outer shells does the Octet Rule state they need?
8 electrons and yes, the Octet rule states this
How many electrons does chlorine need to gain to get full outer shell of electrons?
In a chemical reaction, chlorine will typically gain one electron to have the full octet. This is referred to as the octet rule. Since chlorine has seven valence electrons because it is in row 7A, it gains one so it can have 8 electrons.
How many electrons does sulfur need to be a stable octet?
only 2
How many electrons does fluorine need to satisfy the octet rule?
One
How many more electrons does Fluorine need to have a stable octet?
1
