Answer:
this is Ar, a noble gas, a gas at STP and are basically has little chemical reactivity,
aplanation
:he electron configuration of an element is shown below.
1s^2 2s^2 2p^6 3s^2 3p^6
Based on the electron configuration, write one chemical property of this element.
all of the s an p orbitals ae filled, so this is a noble gas with atomic # =
2 + 2 + 6 + 2 + 6 = 18 so
this ie element #18 and is Argon,Ar
all noble gases are gases at STP and are basically hae little chemical reactivity,a
